Dangar you are the fking man! You have helped me with countless of your videos and if you are ever over to the US and down in Florida I'm going to buy you some beers and take you out fishing. Thank you for your time to help myself and others become more proficient with their outboard engines. To the viewers reading this comment, always look for Dangar's videos first when troubleshooting or preparing to fix your next outboard issue!
You're literally the only person on youtube that explain every detail!!! I've been struggling with syncing my motorcycle. This video helped immensely. MUCH appreciated.
I don't even own a boat yet, but have been learning a lot through your videos. I really appreciate the clarity of your descriptions and speed at which you walk us through each procedure. When I find the right boat, I'll have a lot more confidence in surveying the condition of the engine. Thanks so much and keep them coming!
I have the same motor as you so this video is ideal. Ordered an equalizer and a cheap digital tach at half the price of 1 hours labor of my marine tech so once I tune there will be no doubt that it is done right. Thanks best video yet.
I have now watched all of your videos, some of them more than ten times. I have a 1995 Yamaha f50 and to be true I have never seen anything as pedagogic and useful as this chanel. Many many thanks from Sweden. I owe you.
I have been a Marine Mechanic in Wisconsin for 30+ years. Nice Video and i use the stainless slide type sync from Carbtune. Ordered it from overseas. 100.00 bucks. Love it and nothing better then carbs synced after a tune up.
Your videos on boat motor repairs are Thee Most Informative And Unmatched! I Always Enjoy Learning From You! Saying Thank You Isn’t Enough! Long Live, Dangar Stu⭐️⭐️⭐️⭐️⭐️🏌🏾♂️
I dont know if boat motor carbs have similar stages as automotive carbs but if so here's another tip. When you adjust the mixture screws you are adjusting the fuel through the idle circuit. If the engine rpm increases significantly while making the adjustment the carb will begin to draw fuel from the off-idle circuit, thus upsetting your adjustment. Best to keep the rpm adjusted to an idle speed as you adjust mixture screws so you're working within the idle circuit. Also, it looked like your vac hoses may have been partially pinched at around 23:37. But, as with your previous video's, you are clear and concise, and very detailed. Good videos, thanks.
Great video. It was very helpful on getting my carbs back to normal after I like many others grabbed ahold of the wrong screws when I was trying to drain my carbs when they were gummed up. Rookie mistake. Thank you sir.
This was a great video and walkthrough!! the only bit of advice i would add is, when using multiple vac. gauges like that before you fine tune them its not a bad idea to check and see if they all read the same on 1 carb. sometimes those gauges can read a little differently but than after that you're set!!! great video!! new subscriber
@@levibellette7726 no necessarily that. I just meant before you hook each gauge up to their own carb. check each gauge on the same carb first real quick! Iv'e had 1 out of 4 gauges read off before and messed up my whole tune! just a little tad of advice!:)
I use a mighty vac to test each gauge as a kind of calibration - 10” on the mighty vac reads 9” on gauge 1, 10” on gauges 2 and 3, 11” on gauge 4 - I then grease pencil a +1 on gauge 1 and -1 on gauge 4. Did that make sense? Ha!
Super explanation! It was very concise, direct and not filled with a lot of technical engine mambo jumbo. I understood clearly everything as you explained it. Now I can’t wait for the sun to come up and I can try it for myself. Thanks for sharing your experience and knowledge with us.
Thank You so much for your videos. I've been working on my sisters Mariner 45hp. These videos are so helpful. This started out as just replacing a bad Stator and turned into a Stator, Trigger, CDI, plugged idle valve on bottom carb. learned way more about outboards than I ever wanted to. :)
As a predominantly motorcycle and car mechanic who puts tools down everywhere I'm always anxious for you when watching your vids of tools or parts going in the water. ☺ Nice video mate.
Dangar, I am soooo very happy to have come across your videos. I have learned a lot on how to tackle things that I would have paid for in the past. Just last night I replaced my SS reeds with carbon fiber ones. Again thank you for the viedos and the time that you put into them.
Thanks mate, glad you are enjoying the vids. I think a vid on upgrading to carbon fibre reed valves would be an interesting one, been thinking about that for a while.
Stu I have watched soooo many of your videos. I can’t thank you enough. You’ve helped me do nearly everything for my Johnson and Yamaha outboards. Great work! Great info! Please keep them coming!
Ur instructions are clear, easy to understand and what I appreciate most is you explain everything that is going on and why. I had idle issues with my mercury 40 after a carb clean and after playing with the idle screws I could not get it to stabilise. Either too high or it dies. Did not know there was a setting to bring the whole rpm down to idle properly. Subscribed!!!
I really like your videos, you do a good job. Not to be "that guy" but: I had a Honda twin cylinder motorcycle 17 years ago, first street bike, and got all excited about stuff and found that I could balance the carbs (never had heard of such a thing prior to that). I bought a gauge/device and balanced them. I can't quantify it but it definitely seemed to run better and stronger after balancing the carburetors. It didn't turn it into a rocket ship, but it seemed to make an appreciable difference. I think it's a good final step in tweaking a carb engine.
I've enjoyed viewing your videos tonight. They've given me that bit of motivation to soldier on. I've just spent the weekend on a Yammy F100AET (F100TLRZ) trying to figure out why the alarm sounds then it goes into Limp Mode. After cleaning sensors & changing oils I've come to the conclusion that I'm gonna have to go in hard.... remove the head as there's water in the sump and milk running from the leg. Also while I had the Sump plug out and the flush hose on, found water dripping from the sump plug. Thanks Dangar.
Great vid on carbs. Always professional and most of all knowledgeable . Can’t tell what that means to DIY people like me great Job I feel inspired and excited and looking forward to getting back on the water with less stress or worries!!! Means a lot thanks Mate!!!
Thanks a ton! I am just about to endeavor doing this very task and you have clarified it for me perfectly.Now I know how to adjust the fuel idle mixture as with 3 carbys to do,I was somewhat clueless as to the proper procedure.This video makes it look a breeze and just as soon as I rebuilt them I'll be getting stuck into them.It makes it look so easy!
Best material on outboard tuning I've seen! I have a BF25 Honda that looks to be quite similar to what you're working on so even better for me. I've struggled a bit with this motor the last several years but the trend is positive :). Have had issues with dirty fuel and build-ups in the very small passages in the carbs so have, of necessity, gotten comfortable with disassembling / cleaning these guys. The final tuning / balancing however, has been a work-in-process even with the factory manual but your video puts it all together beautifully! Thanks much (and big snaps for not dropping anything in the water at the dock...I can't claim the same when working on the boat in the water :).
Thanks Mark, yep, those BF25s are very similar. Glad to hear the videos have been helping you, but yes, I have dropped plenty of tools and parts in the water over the years...
good video.done this procedure many times.i use a vacuum mate though.set the idle to 1000 rpm,and keep it at that rpm for the procedure.if you have balance tubes between the carbs,pinch them with plastic pinch off tool.takes some patience,but once done your engine will purr at idle.once al carbs are in sync,set idle speed back to specs.happy boating.
i`ve been doing marine repairs for 40+ years.i have to say that your videos are first class.you take the time to describe all procedures in depth.great analyzing and diagnostic skills.your explanations are clear and concise.i salut you sir,keep up the excellent work.best wishes from Canada.
@@lizaanvanderbergh6648 the carburettor/s are most likely to be flooding,, the float valves may be stuck down,, by the way,, too check your "reed valves are working right,, take off the air box on the carburettor's and run your engine holding a white card close to the front of each carburreter if any fuel is spitting out on the card then that cylinder's reed valves are bad,, not setting or are broken! if one is broken you MUST find all of the reed valve,, don't just swop out the reed valve without finding the broken part,, as it very likely to find its way into your engine when its running,,,, then your engine go's with a bang!,, and you get one written off engine!,, so find all the broken off part's!
I meant to add.......you tube is great but too many guys think they are media personalities or leave the camera on while they tighten a bolt. You get straight to the point and there are no 'dull' parts where I have to watch you spray paint the engine or something asinine. In other words, you are not just a good mechanic and a great you-tuber, you are also a great editor. Much appreciated.
Your videos are very informative and you go in great detail. I will use this information to try & get my motor set. Thanks for the descriptive tutorial... will follow and looking forward to more.
I followed your procedure step by step for my bf25a and I gotta say...thank you so much for making this video...it helped me out so much when I had doubts about some of the screws effects.
I had a beast of a time adjusting a BF90. Two of the mixture screws had the tip broken off in the seats... I managed to drill them out with a magnifying glass and a dremel with a tiny, tiny drill bit. Installed new screws and redid the sync. Ran beautiful after that. It only took me a days work all in all :D
Thanks for this. I have a new (to me) 1998 115 Johnson running rich. I hope this applies. As soon as Hurricane Harvey is done thrashing us here in south TX I'm going to give it a go. Keep up the good work!
Hi Sir. First class training video. Much appreciate. It helps me to understand the synchronization process with the tool, the small valves and the adaptors ... And your common sens tricks are great to know. Thanks, enjoy life ! Jeff
Man I have to say... Your videos have been so helpful. I have been working with 98 Johnson 60hp 2 stroke. Everything from the reed valves video to the card clean and sync videos. Keep up the good work!! Now I have to find the Vac screws on my in take and do a sync I have the motor running fairly good. Just some last fine tuning.
Hey Eric, glad the videos have been helping you. 2 stroke motors don't have induction runners like 4 stroke motors so this is more the procedure you would follow ruclips.net/video/NnotQmnKxKM/видео.html
Thanks very much for your well done, clear, and informative videos! I just got a 90 hp 3cyl merc running that hasn't run for over 12 yrs. cleaned and new gaskets in carbs, rebuild fuel pump, all new fuel lines. It runs pretty well but has,what I'm told, a lean pop, that will almost stop the engine. So next I'll do all you have shown in this video. Greatly appreciate your videos.
AWESOME!!! Thank you! Tthese videos have made me a lot more competent and confident to service my own motor. As a result, I've had a wonderful season on the water! Thanks again, sir!
@@DangarMarine , I imagine you are really busy but I can't seem to find the vacuum ports to put the synchronizer lines? 2005 Mariner 90hp 2 stroke. I've looked everywhere on the wen but nothing specific to my model?
Fun fact: Mercuruiser stern drives have an interrupter switch that actually turns ignition off for a few milli seconds as the unit is shifted from neutral . This protects the shift components in the bottom end. Works quite well. Don't know if outboards have similar tech, but they should imho.
yes of course outboards have a "shift interrupter" switch. if its a v4, kills one bank of cylinders so its easy on the pinion gear. a V6, 3 cyl (entire port or std. bank). anything smaller than a v4 and its not an issue. although many v4's dont need one depending on the gearcase.
Man your videos Rock! Very informative 👍👍. I just bought a 93 Suzuki DT225 and it's giving me hell... I guess it would help if I knew anything about outboards but umm.. it's my first. I'm good with a wrench so with your help I was able to do alot of the basics to it but, it still stalls out and doesn't open up all the way ughhhh . Could u please lend me some of your expertise. Compression is at 130, 130, 130, 125, 130, 130, 115, 115, 125, 130, 130, 130 Thanks for all u do and please keep it up😎
Fantastic informative vid, thanks. Trying to sort out the carbs on a classic bike and my next search was gonna be how to get the mixture right, but I think you've covered it. Thank again and keep em coming
Great video!! Very informative! I have an 85 Mariner 75 hp I have a hard starting problem with. I replaced the fuel pump, fuel lines and rebuilt the carbs. It runs great but it is very hard to start. It has a fuel enrichment system instead of a choke. The solenoid is working and all passages are clean, but I still have to spray gas into the carbs to crank it when cold.
The stator went out on my last trip. I'm thinking that may have been my hard starting problem. I have a new stator, power pack, and voltage regulator ordered. Hopefully that will cure the hard start problems.
I certainly will! I have plenty of experience working on motorcycles, cars, and atvs. I'm not as experienced with outboards, but this particular engine is a demanding school mistress...LOL. While it was running, it was flawless and powerful. I'm quite sure the new ignition system will solve my problems. Again, thanks for the concise and informative videos! I will update my results this weekend! PS. I had the engine rebuilt for $1250. I kept having carb problems. After installing an inline filter and cleaning carbs, they started flooding again. I tore them back down and they were loaded with black debris. I replaced all the fuel line inside the cowl. It was dared 3/24/86...LOL. I thought he would've replaced the fuel line. I would hate to fry a motor over a $10 length of 1/4 id rubber hose...smh.
It does not surprise me brother that you don't even have one dislike there that was excellent it's exactly what I was looking for I appreciate you so much keep up the great work. Question can you do something on timing so we can figure out if our timing is okay how to do it that kind of stuff I've got a 1999 Yamaha 115 two stroke I'm pretty sure everything on that motor is going to be just like the one you were working on again God bless you brother thank you
Gday mate another brilliant video ,this was always something i would take tomy outboard mech ,1 i didnt have the vac gauges and 2 i wasnt confident as i had never done it before or been shown , brave man doing it over the water my luck i would have dropped all the screws and the screwdriver in .
This video I felt was pretty cut and dry. Very helpful and it all made perfect sense to me. Thank you for taking the time to explain all of this. Great videos!
Keep up the great work with these videos - they're a fantastic series that are really helpful for people that don't have a lot of experience. I have lots of carb fun with a Honda BF90 I have, where it sometimes drops to 3 cylinders when idling, despite stripping/cleaning/tuning/balancing all the carbs. They're temperamental things on the hondas I think, as my friend's one does the same thing, but not sure why it does this 'trick'.
Hi Jim, glad you like the vids. Dropping a cylinder is more likely to be a spark problem than a carburettor problem. I'd go through that side of this next.
Thanks for the input! Have used a spark tester on all 4 and it seems to work fine on them all whether it's going on all 4 or dropped down to 3, and have swapped the plugs & coils etc around. Just taken the carbs off yesterday anyway and the bottom one wasn't the cleanest inside (float was sticking, causing it to absolute p*ss fuel out of its vent at the top), so I'm overhauling them all. Water jacket cover etc is all off at the same time to de-salt it all too, as a previous owner has clearly been pretty slack with rinsing it out adequately. Lots of new coolant related bits ordered as it's been a bit neglected. Now if I could just get the honda paint that'd be the holy grail but can't even really find it for sale in the UK, never mind the Isle of Man!
On my 2006 merc 125 hp the it really idles hi and clunks into gear. I wasn't sure the idle was to blame but this vid narrowed that down nicely. While I'm not sure I want to start turning fuel screws I might just simply lower the idle as you say until is comfortably slower but not out of balance. Thanks Stu, very well explained video as always....cheers
thank you I am currently fighting with a BF30 with fuel issues. Hopefully I have it sorted. I have been following your videos all the way through. Now I start on a Yamaha F150 that hasn't been started in two years so on to clogged injectors :/
Glad to hear the vids have been helping you. Good luck with the F150. There are plenty of placed that can professionally clean injectors for you for not too much money.
Hey Stu. Hope all is well Down there. Quick story for you. Remember your trailer wheel bearing video?? Well, using that, I did the bearings and hubs on my Kayak trailer. Took it 1500 miles from New Jersey, USA all the way to Tampa Bay Fl. No problems Even new wheels, new tires( Amazon) . All is good. THEN for my big boat trailer. A double axle that carries a 21 foot PRO LINE, 150 HP Mercury, 70 gallons fuel etc. My point..good deal of weight, right? Well I bought the boat used( the boat is a fishing boat and just needed cleaning). Used your videos to do my own repairs, but last year I brought her to a trailer repair center for a 'PRO" to do the bearings. Last week I took it in for new tires at a tire store, the tech came out and said a wheel was seized !We thought the brakes where not releasing. To make a long and expensive story short, the trailer Pro never replaced the bearings on all four wheels. The bearing came out in pieces when I took the brake off. The grease was covered in rust( the trailer has not seen salt water yet) One race was broken and stayed on the axle The techs at the tire brake shop said the bearings were never changed.I did grease thru the bearing buddy but never broke them down to inspect thinking they were new. Less than one hundred miles. Thanks to your videos not only did I do up my kayak trailer and put over three thousand miles on it but I was able to find a problem on my big boat trailer and brought back to the PRO and demand they repair it right. So, if you ever wonder if your videos make a difference, well guess what, they do!!! Thank you. If did not live 10000 miles away I would buy you a beer .Doug Bryer, New Jersey USA. Ever do anything with that fishing pole in your shed ? I think you said it was your father in laws?????
+Doug Bryer Hey Doug, glad hear that vid helped you. Hope the "pros" sort out their effort. It's amazing how many cars come into our shop that have never has fuel filters or cabin filters changed ever because they are hard to get to. I did get that rod up and running in the end. Just posted a picture of it on Instagram for you.
Hey Stu, remember my bearing story?? Well I forgot to mention the brakes would keep locking up on the trailer and would not work. Well the day I brought the trailer back to get "fixed" the tech said the brakes were mounted wrong( they did the brakes). The drum brake backing plate was mounted sideways. This in turn caused the wheel cylinder to be vertical, causing an air pocket. The push rod was bent, and presto, no brakes. Well, again. a long story made short. The owner of the job said he took care of everything. He replaced the bearing and that he would "eat the cost". He said the brakes were fixed and ready to go. Well I traveled 7 miles to the lake boat ramp and as soon as I got out of my truck i smelled something burning. The axle with the "repaired" brakes was burning hot. ( the dust cap was to hot to touch) So , back to the drawing board. My regular auto mech. shop said I should change over to disk brakes. He said its a easy job, and since i did my small trailer, I could do my boat trailer myself. So my question is , do disc brakes hold up on boat trailers???? I see they come as a kit and look easy to do,vs drum brakes and all those springs. Again thanks for the video. You most likely saved me lots off grief since I was able to check the work of the "trailer shop".Word is in town is that a lot of work has been going back to him . Thanks again for the videos and information. Doug from Byram Nj,USA I was going to send you a case of Beer to says thanks and well done, but the US Post office would not let me. some about over seas shipping and beer and the law???????
I appreciate you sharing this with us, it really helps. I tried to mechanically (as I don't have a vacuum gauge rack; which I will need to get) sync the carbs on my Honda 40 by setting the adjustments as close together as possible according to the small holes in the bottom of the circuit (lined up according to the boss carb.) We will see if it works, I know it did work on my motorcycle to do it that way. My motor was all jacked up...I cleaned the carbs and reset the mixture jets. Next is the sync, thanks mate for showing me how!
Dangar you are the fking man! You have helped me with countless of your videos and if you are ever over to the US and down in Florida I'm going to buy you some beers and take you out fishing.

When I find the right boat, I'll have a lot more confidence in surveying the condition of the engine. Thanks so much and keep them coming!
Thanks Sam. Sounds like you're going about it the right way to learn as much as you can before you choose your boat. Good luck!
You lay your money down, and take your chances.

It's always nice when you can buy the tools to keep and still have spent less money. :)
Great comparison with tuning a guitar. Always a pleasure watching your tutorials especially with a stubbie in the foreground. Thank you!

This worked like a charm. My BF30A purrs like a kitten now when trolling. Thank you very much.
Your demonstration videos are always the best for all outboard situations/conditions. Thx again!
Thanks mate.

Very useful information. I haven't done this since I tuned a Honda 4 cylinder motorcycle... so good refresher
Thanks Ray.
As a predominantly motorcycle and car mechanic who puts tools down everywhere I'm always anxious for you when watching your vids of tools or parts going in the water. ☺
Nice video mate.
I hear you brother, I'm always losing tools in the workshop so I try to be more careful on the water but it doesn't always go to plan...
I keep a large magnet on a rope for retrieving tools lost off the boat or dock, seems to work alright.
You are the most intelligent repair person i have seen..thanks man!!

Thanks Mark, yep, those BF25s are very similar. Glad to hear the videos have been helping you, but yes, I have dropped plenty of tools and parts in the water over the years...
Dangar Marine Tappets
good video.done this procedure many times.i use a vacuum mate though.set the idle to 1000 rpm,and keep it at that rpm for the procedure.if you have balance tubes between the carbs,pinch them with plastic pinch off tool.takes some patience,but once done your engine will purr at idle.once al carbs are in sync,set idle speed back to specs.happy boating.
Those VacuumMates look really cool. You're not wrong about it getting the boat purring once it is done. :)
i`ve been doing marine repairs for 40+ years.i have to say that your videos are first class.you take the time to describe all procedures in depth.great analyzing and diagnostic skills.your explanations are clear and concise.i salut you sir,keep up the excellent work.best wishes from Canada.
The 86 people that gave you a thumbs down must just not like your accent. Thanks stu, very helpful
The most helpful & nice video in RUclips!!! Thank you very very much!I slow down to 75% speed and saw this video 3 times. lol
The most informative vid I've seen on this subject. Thanks for that! I love the plain, no frills vids that relay information. 👍
Thanks Joseph, glad you liked the video. :)
If a start my 75 mariner moter and it is running the fuel pis out my moter in to may transim of my boat
Lizaan van der Bergh bad reed valves if it’s a 2 stroke
@@lizaanvanderbergh6648 the carburettor/s are most likely to be flooding,, the float valves may be stuck down,, by the way,, too check your "reed valves are working right,, take off the air box on the carburettor's and run your engine holding a white card close to the front of each carburreter if any fuel is spitting out on the card then that cylinder's reed valves are bad,, not setting or are broken! if one is broken you MUST find all of the reed valve,, don't just swop out the reed valve without finding the broken part,, as it very likely to find its way into your engine when its running,,,, then your engine go's with a bang!,, and you get one written off engine!,, so find all the broken off part's!
I put my boat together from your vid’s I’m a expert now thank you
That sir was the best explanation i have ever heard, thankyou very much
You're welcome, glad the video helped you.
For a doofus like me, you working on what looks like a Honda 50 (my motor) is HUGE! Thanks.
You're welcome. This is a 40 but the principle is the same for almost all four strokes.
I meant to add.......you tube is great but too many guys think they are media personalities or leave the camera on while they tighten a bolt. You get straight to the point and there are no 'dull' parts where I have to watch you spray paint the engine or something asinine. In other words, you are not just a good mechanic and a great you-tuber, you are also a great editor. Much appreciated.
Thanks mate. I know I go through quite a bit of talking theory in some videos but I try not to make them too boring! :)
Your videos are very informative and you go in great detail. I will use this information to try & get my motor set. Thanks for the descriptive tutorial... will follow and looking forward to more.
Glad to help
Thanks, I have done that to my Suzuki GSX-F 750 with same type of synchronizer. Nice to learn more and now with boat engines.
I followed your procedure step by step for my bf25a and I gotta say...thank you so much for making this video...it helped me out so much when I had doubts about some of the screws effects.
I had a beast of a time adjusting a BF90. Two of the mixture screws had the tip broken off in the seats... I managed to drill them out with a magnifying glass and a dremel with a tiny, tiny drill bit. Installed new screws and redid the sync. Ran beautiful after that. It only took me a days work all in all :D
awesome video . i learned so much in 30 min. tomorrow i will do the same to my 60 horse mariner after a few upgrades.
Thanks mate, good luck!
Very good video sir thank you from the 🇺🇸 North east!!!! 👍🏻👍🏻
I’m looking at purchasing a Honda 2006 Bf 40 tiller I’ve been told they are a good engine thoughts...?
Yes, those Hondas are very good engines.
Thanks again for your helpful Videos. Keep up the great work... From Germany
Thanks for this. I have a new (to me) 1998 115 Johnson running rich. I hope this applies. As soon as Hurricane Harvey is done thrashing us here in south TX I'm going to give it a go. Keep up the good work!
Thanks Charles, the mixture screw part should solve your problem. Stay safe in the Hurricane!
Hi Sir.
First class training video. Much appreciate. It helps me to understand the synchronization process with the tool, the small valves and the adaptors ... And your common sens tricks are great to know. Thanks, enjoy life ! Jeff
Thanks Jeff!
Man I have to say... Your videos have been so helpful. I have been working with 98 Johnson 60hp 2 stroke. Everything from the reed valves video to the card clean and sync videos. Keep up the good work!! Now I have to find the Vac screws on my in take and do a sync I have the motor running fairly good. Just some last fine tuning.
Hey Eric, glad the videos have been helping you. 2 stroke motors don't have induction runners like 4 stroke motors so this is more the procedure you would follow ruclips.net/video/NnotQmnKxKM/видео.html
Great video and great information about turning your carbs. I think that you have given me the answer to the problem that I have been having.
just amazing , thanks very much,from Long Island NY.(Nino).
Thanks very much for your well done, clear, and informative videos! I just got a 90 hp 3cyl merc running that hasn't run for over 12 yrs. cleaned and new gaskets in carbs, rebuild fuel pump, all new fuel lines. It runs pretty well but has,what I'm told, a lean pop, that will almost stop the engine. So next I'll do all you have shown in this video. Greatly appreciate your videos.
AWESOME!!! Thank you! Tthese videos have made me a lot more competent and confident to service my own motor. As a result, I've had a wonderful season on the water! Thanks again, sir!
That's what I like to hear. Glad you had a great season, I can't wait for ours to start! :)
@@DangarMarine , I imagine you are really busy but I can't seem to find the vacuum ports to put the synchronizer lines? 2005 Mariner 90hp 2 stroke. I've looked everywhere on the wen but nothing specific to my model?
Extremely helpful and clear, really appreciate it. I really enjoy all your vids, thanks!
Thanks Andrew, glad you enjoyed it. :)
Really appreciate the competence and quality in your videos awesome dude
Fun fact: Mercuruiser stern drives have an interrupter switch that actually turns ignition off for a few milli seconds as the unit is shifted from neutral . This protects the shift components in the bottom end. Works quite well. Don't know if outboards have similar tech, but they should imho.
yes of course outboards have a "shift interrupter" switch. if its a v4, kills one bank of cylinders so its easy on the pinion gear. a V6, 3 cyl (entire port or std. bank). anything smaller than a v4 and its not an issue. although many v4's dont need one depending on the gearcase.
Man your videos Rock! Very informative 👍👍.
I just bought a 93 Suzuki DT225 and it's giving me hell... I guess it would help if I knew anything about outboards but umm.. it's my first. I'm good with a wrench so with your help I was able to do alot of the basics to it but, it still stalls out and doesn't open up all the way ughhhh . Could u please lend me some of your expertise. Compression is at 130, 130, 130, 125, 130, 130, 115, 115, 125, 130, 130, 130
Thanks for all u do and please keep it up😎
Fantastic informative vid, thanks. Trying to sort out the carbs on a classic bike and my next search was gonna be how to get the mixture right, but I think you've covered it. Thank again and keep em coming
You're welcome mate. Yes, the process is pretty much the same for a motorbike.
This was a great video how I explained each carburetor may be adjusted a little different.
I'll echo what others have said.Very clear explanations. I learned a lot.Thank's for the great video.
Thanks Tim, glad you liked it.
Very good and impressive video. I never knew there was so much involved in tuning the carburetors. Thanks Stu
Just subscribed. Easy to follow common sense tutorials on marine maintenance. Happy Boatie.
love your videos! going through an old Johnson qd-14 and cd-11 your videos have helped tremendously.
Glad to help!
Que capo que sos! gracias todos los videos que subís me están ayudando un montón! Saludos desde Argentina
Great video!! Very informative! I have an 85 Mariner 75 hp I have a hard starting problem with. I replaced the fuel pump, fuel lines and rebuilt the carbs. It runs great but it is very hard to start. It has a fuel enrichment system instead of a choke. The solenoid is working and all passages are clean, but I still have to spray gas into the carbs to crank it when cold.
Once it is running, does activating the enrichment solenoid change the sound of the motor?
+Dangar Marine Yes, it bogs down like it is getting extra fuel.
The stator went out on my last trip. I'm thinking that may have been my hard starting problem. I have a new stator, power pack, and voltage regulator ordered. Hopefully that will cure the hard start problems.
Fingers crossed. Let me know how you get on.
I certainly will! I have plenty of experience working on motorcycles, cars, and atvs. I'm not as experienced with outboards, but this particular engine is a demanding school mistress...LOL. While it was running, it was flawless and powerful. I'm quite sure the new ignition system will solve my problems. Again, thanks for the concise and informative videos! I will update my results this weekend! PS. I had the engine rebuilt for $1250. I kept having carb problems. After installing an inline filter and cleaning carbs, they started flooding again. I tore them back down and they were loaded with black debris. I replaced all the fuel line inside the cowl. It was dared 3/24/86...LOL. I thought he would've replaced the fuel line. I would hate to fry a motor over a $10 length of 1/4 id rubber hose...smh.
It does not surprise me brother that you don't even have one dislike there that was excellent it's exactly what I was looking for I appreciate you so much keep up the great work. Question can you do something on timing so we can figure out if our timing is okay how to do it that kind of stuff I've got a 1999 Yamaha 115 two stroke I'm pretty sure everything on that motor is going to be just like the one you were working on again God bless you brother thank you
Great job on explaining that, and how simple it is with the right tools.
Thanks Bryan!
Thanks a lot sir... we love your presentations and great videos ... carry on .. god bless you
I have buy de exact same engine, little iddle problems. Thankss! Voor the video👌🏻👌🏻
Good video. I learned quite a bit and ready to tackle tuning up my outboard.
Thanks mate, good luck with the tune up. :)
The ol’ “Fender noise”.. no dog around to blame it on hey ;) Grea video mate cheers!
Gday mate another brilliant video ,this was always something i would take tomy outboard mech ,1 i didnt have the vac gauges and 2 i wasnt confident as i had never done it before or been shown , brave man doing it over the water my luck i would have dropped all the screws and the screwdriver in .
Oh yes, I've certainly dropped my fair share of tools in the water!
I absolutely love watching all of your videos thank you for sharing your knowledge
Brilliant clear explanation. Thanks. VERY helpful.
You're welcome!
love your videos never worked on outboard motors before but hell these vids bloody neer make a machanic out of me thanks dangar
Thanks Tony, glad the vids are helping you. :)
You make the best videos! Thank you!
Thanks Paul!
You have an amazing channel.
The most informative video I've seen on this topic. Thanks for that
You're welcome, glad you liked it. :)
This video I felt was pretty cut and dry. Very helpful and it all made perfect sense to me. Thank you for taking the time to explain all of this. Great videos!
You r top class mechanic,great videos.
Thanks Ronald, glad you like the vids. :)
Keep up the great work with these videos - they're a fantastic series that are really helpful for people that don't have a lot of experience. I have lots of carb fun with a Honda BF90 I have, where it sometimes drops to 3 cylinders when idling, despite stripping/cleaning/tuning/balancing all the carbs. They're temperamental things on the hondas I think, as my friend's one does the same thing, but not sure why it does this 'trick'.
Hi Jim, glad you like the vids. Dropping a cylinder is more likely to be a spark problem than a carburettor problem. I'd go through that side of this next.
Thanks for the input! Have used a spark tester on all 4 and it seems to work fine on them all whether it's going on all 4 or dropped down to 3, and have swapped the plugs & coils etc around. Just taken the carbs off yesterday anyway and the bottom one wasn't the cleanest inside (float was sticking, causing it to absolute p*ss fuel out of its vent at the top), so I'm overhauling them all.
Water jacket cover etc is all off at the same time to de-salt it all too, as a previous owner has clearly been pretty slack with rinsing it out adequately. Lots of new coolant related bits ordered as it's been a bit neglected. Now if I could just get the honda paint that'd be the holy grail but can't even really find it for sale in the UK, never mind the Isle of Man!
Awesome video. Very simple, well explained and clear. Not bad for an Aussie ;-)
LOL. Thanks! ;)
On my 2006 merc 125 hp the it really idles hi and clunks into gear. I wasn't sure the idle was to blame but this vid narrowed that down nicely. While I'm not sure I want to start turning fuel screws I might just simply lower the idle as you say until is comfortably slower but not out of balance. Thanks Stu, very well explained video as always....cheers
For sure I would lower the idle if it is really clunking. As you say, no need to mess with the mixture screws if it is running nicely.
Great Stu...always wondered how multiple carbs are tuned... my outboards have only ever had one
Thanks mate, sometimes I think you can't beat a nice simple single carb outboard.
thank you I am currently fighting with a BF30 with fuel issues. Hopefully I have it sorted. I have been following your videos all the way through. Now I start on a Yamaha F150 that hasn't been started in two years so on to clogged injectors :/
Glad to hear the vids have been helping you. Good luck with the F150. There are plenty of placed that can professionally clean injectors for you for not too much money.
Hey Stu. Hope all is well Down there. Quick story for you. Remember your trailer wheel bearing video?? Well, using that, I did the bearings and hubs on my Kayak trailer. Took it 1500 miles from New Jersey, USA all the way to Tampa Bay Fl. No problems Even new wheels, new tires( Amazon) . All is good. THEN for my big boat trailer. A double axle that carries a 21 foot PRO LINE, 150 HP Mercury, 70 gallons fuel etc. My point..good deal of weight, right? Well I bought the boat used( the boat is a fishing boat and just needed cleaning). Used your videos to do my own repairs, but last year I brought her to a trailer repair center for a 'PRO" to do the bearings. Last week I took it in for new tires at a tire store, the tech came out and said a wheel was seized !We thought the brakes where not releasing. To make a long and expensive story short, the trailer Pro never replaced the bearings on all four wheels. The bearing came out in pieces when I took the brake off. The grease was covered in rust( the trailer has not seen salt water yet) One race was broken and stayed on the axle The techs at the tire brake shop said the bearings were never changed.I did grease thru the bearing buddy but never broke them down to inspect thinking they were new. Less than one hundred miles. Thanks to your videos not only did I do up my kayak trailer and put over three thousand miles on it but I was able to find a problem on my big boat trailer and brought back to the PRO and demand they repair it right. So, if you ever wonder if your videos make a difference, well guess what, they do!!! Thank you. If did not live 10000 miles away I would buy you a beer .Doug Bryer, New Jersey USA. Ever do anything with that fishing pole in your shed ? I think you said it was your father in laws?????
+Doug Bryer Hey Doug, glad hear that vid helped you. Hope the "pros" sort out their effort. It's amazing how many cars come into our shop that have never has fuel filters or cabin filters changed ever because they are hard to get to. I did get that rod up and running in the end. Just posted a picture of it on Instagram for you.
Hey Stu, remember my bearing story?? Well I forgot to mention the brakes would keep locking up on the trailer and would not work. Well the day I brought the trailer back to get "fixed" the tech said the brakes were mounted wrong( they did the brakes). The drum brake backing plate was mounted sideways. This in turn caused the wheel cylinder to be vertical, causing an air pocket. The push rod was bent, and presto, no brakes. Well, again. a long story made short. The owner of the job said he took care of everything. He replaced the bearing and that he would "eat the cost". He said the brakes were fixed and ready to go. Well I traveled 7 miles to the lake boat ramp and as soon as I got out of my truck i smelled something burning. The axle with the "repaired" brakes was burning hot. ( the dust cap was to hot to touch) So , back to the drawing board. My regular auto mech. shop said I should change over to disk brakes. He said its a easy job, and since i did my small trailer, I could do my boat trailer myself. So my question is , do disc brakes hold up on boat trailers???? I see they come as a kit and look easy to do,vs drum brakes and all those springs. Again thanks for the video. You most likely saved me lots off grief since I was able to check the work of the "trailer shop".Word is in town is that a lot of work has been going back to him . Thanks again for the videos and information. Doug from Byram Nj,USA I was going to send you a case of Beer to says thanks and well done, but the US Post office would not let me. some about over seas shipping and beer and the law???????
Great video, very clear and easy to follow along. Thanks a million!
very informative with the service video and this one I don't see if your attentive what your doing you can't service any engine.
great videos 👍👍
I appreciate you sharing this with us, it really helps. I tried to mechanically (as I don't have a vacuum gauge rack; which I will need to get) sync the carbs on my Honda 40 by setting the adjustments as close together as possible according to the small holes in the bottom of the circuit (lined up according to the boss carb.) We will see if it works, I know it did work on my motorcycle to do it that way. My motor was all jacked up...I cleaned the carbs and reset the mixture jets. Next is the sync, thanks mate for showing me how!
