I love watching a technician that knows what he’s doing very impressed
thanks :)
Hey how many hours are on those engines ? Just interested to know
@@crustymac1326With a cylinder down that baby's gotta have more than 700hrs, at least or abused.
Not sure that I approve. This engine called for a thorough valve job at minimum. A wet/dry compression test would have revealed the condition of the piston rings. If all yo7 want to do is “get the motor running” as Steppinwolf said, then ok, but taking the head off is more than halfway to a valve job/piston ring overhaul.
You should never clean the cylinder head and engine block deck with a scotch bright pad it creates low spot inperfections.
Man I love this channel, you can't get anything more real than this, good job guys!
thanks so much!
@Born Again Boating what are symptoms of blown head gasket on a 2 stroke. And can it be possible to have fantastic compression but a failed leakdown test.
I reconstructed half of the thermostat housing on a Yamaha 9.9 "Kicker""Trolling" motor with J.B.weld and sold the boat 2 years later.I told the new owner about the repair and as far as I know it still works.CHEERS from Here!
Really wish this dude was near my location. I'd feel very comfortable with him servicing my boat year round.
hes right about j b weld it works i have used it several times my son had freon leak on his ford i fixed with j b weld i used it on an out board motor highly recomend j b weld
Great job with the fix and ultimately saving the customer big dollars!
You guys are amazing that you can turn this project around in a day. Kudos to both of you!
I really enjoyed this longer video. You gave that engine a second life!
Great channel! I mix my jb weld on a metal plate and heated, until it got liquid some what. Then applied it. Worked well had no issues. Good luck, boys!!
Nice work!
Interesting fix for the Merc.....Had a simple fix for my Proline fuel system the other day and you folks had the part to get my vacation off to a great start with a 25 lb. Wahoo.....Sea Ya!!
Definitely a $3000 repair , even with JB Weld . Nicely done in a day, unreal , what dedication.
Assemble the motor and run a few quarts of seafoam & good non ethanol fuel.. should help some of the build up. My Merc 25 had that same build up of carbon and after running seafoam through it , seemed to do the trick
good part about you can sand it if needed in an hour in summer time i dont use below 65 deg.
That was a great trick with the die grinder and abrasive pad!
Well done Gents.
Extremely impressive. Overcome and adapt.
Once again you guys are “the man”!! Thanks for the education.
You bet!
These outboards can be worth more than the boat. The game is more technical than ever and the investment for multiples can be enormous. My outboard guy was old school and always pulled the heads before pronouncing on a motor. He never steered me or anybody else wrong.
Oh no... We must take this boat out to test it in gorgeous weather! Great channel and you inspire me to take better care of my boat although its a fresh water boat so I think I have it easy! :D
This video made my backwoods tactics look good lol. Thank you for moving forward no matter the issue, what matter was results.
It is amazing what you can do with in weld.
I have repaired jet ski carb throttle shaft bushing surfaces,the actual carb casting, with in weld. I never thought it would hold but it did. Saved from buying a $900 set of carbs with $10 of in weld.
Outboards are CRAZY expensive for what they are. For $20K you could buy the Highest end racing engine for a car. Not just a old 250hp Verado.
I love this guy. He's sharing his knowledge and expertise with us. Stuff that takes years of experience to learn or expensive training. I learn so frigging much from everyone of his videos. He teaches in a complete and thorough way and keeps it all visual and in layman's terms. Bro I can't thank you enough. No local mechanic I know would take the time to show me how to do his job😂. I live in Florida near Daytona beach. Id love to meet you someday and shake your hand and thank you personally. Thank you again for being such a good guy.
Thanks so much man. It will be a pleasure to meet you too!
There’s another video for your library, good job.
This guy is genius 👍 excellent job 👍
I think the $300 must have been for the JB Weld fix alone.
Great episode! I had an old Evinrude 25 from the 80's. Excepte crept for the valves, I think I made all of those qwick repairs over the years. She eventually developed a pretty nasty knock. I felt like I got all of the life I possibly could from that motor. Nice watching you guys work. ✌🏼
I think saying how old the engine is and how many hours it has would add to the video content. Great job! Are there any additives / products that cut down on the carbon buildup?
Seafoam
I think he used that same motor in a "Flushing Info" video and said the Impeller had about 200 hours on it, but didn't say if it was the original impeller. So apparently the motor has at least 200 hours on it.
Yeah definitely that motor has more than 200hrs on it.
Power tune in the throats
What was the repair cost? Great job. You guys always hit the mark. My lower oil seal under the power head is leaking slightly. Wondering what I might be in for to remove powerhead and replace it.
Replacing that gasket is pretty easy. Disconnect everything that attaches the power head to the bottom housing. Remove the bolts/nuts (depending on motor) and lift up. Remove and replace the gasket and reassemble.
You should disassemble the whole damn thing to make your work more efficient. Clean up and repair damaged items piece by piece and assemble them back nicely.
I agree, he should of stripped it down to the bare block. He may have warped heads on a engine that old. It had 1,822 hours !
I wish you guys were in Crystal River
You guys are very talented mechanics!!!!
We just pulled a couple power heads on mercury twin 300s. Let me tell you what, that was a process getting them both broke loose
The cam gear bolts are reverse thread? I guess im definitely getting a suzuki. No reason why any motor should be prone to jumping timing if made within the past 15 to 20 years.
Extremely satisfying to see you bring this one back to life!💯 👍
I enjoyed the video. I loved the troubleshooting parts. As a shade tree mechanic, this is a project I would definitely do. JB weld, bring it!
Man bro it’s crazy that you know so much about this trade keep up the videos and knowledge
Nice fix. I love your videos. What caused that cooling fitting to fail below the powerhead in your opinion? Do you ever de-scale outboards? Thanks for another informative video!
You’ll never make me believe that you only charged a customer $300 for this fix. Maybe a close friend or family member with that brother in law price.
Im assuming it's 300 in materials. Bc im a boat mechanic and i know it will definitely be more than that.
Your 100% right i work on boats and thats definitely not parts and labor
I think 300 for leak test :)
thats his personal boat
Not everyone likes their brother in law...
Jb weld should be sponsoring the channel with good review like that
Another save from the scrap pile
Impressive gentleman I enjoyed watching that.
Now I know why that brand new 1993 200 merc I bought head gaskets always leaked. It was that special mercury torquing technique. 😂
Wish you were located in the tampa Bay Area 👍. This guy knows what he’s doing
I put jb weld on my sons truck on the water thermostat housing going into the block. It has held couple years now no problem that perfect for jb weld
Good vid man, listening to it while getting out fuel with water in it out of a boat lol fun job
so jb weld is how we fix them , give me an old 2 stroke
Damn strong hands..
Awesome vlog.
You know your stuff young fella 👍
A regular 5-inch orbital Dewalt sander is much easier to use for cleaning surface area's
Great work. How many HRS are on the motor, sry if it you said it. A little freshwater wouldn't hurt. Wow, rinse.
Sir, 1,822 Hours.
So Merc also has a cam chain now!
I thought that the Suzy's was the only brand that had those.
For rust muriatic acid aka pool acid works wonders
What was the cause of the carbon build up ? Any ideals ?
should done complete engine rebuild...
I have hard of doing it cheap.... but what kind of customer is going to be okay with the fix being JB weld? Usually I see very professional fixes from this channel but not today.
There is no proper fix other than throwing it out and buying a new one. JB Weld bought the customer some time that's all.
Great video. What was the decarbonizer product you used?
How many hours on that motor ? Did they periodically use any fuel treatment?
11822 hrs. ......Doesn't look like any treatment was done beforehand.
As a former aircraft mechanic, but in my defense, I worked on turbines, I can't figure out how the leak down differs from a compression test. Obviously not the test, but what would a compression test tell us about a leaking head? Or.. would it not locate it accurately??
It doesn't work the same because there is a check valve in the compression tester hose that allows the pressure to build in the gauge with every stroke. Then holds it there to get the compression reading. The leak down doesn't have a valve and puts pressure in the cylinder
Momentary vs continuous. You need a constant flow(leak down) of air to pinpoint a leak. Also all valves need to be in closed position.
If you hear/see air leaking through:
1. Exhaust = exhaust valve issue
2. Intake/throttle body = intake valve issue
3. Cooling/coolant = head gasket
4. Crankcase/dipstick = piston rings.
From the 100' view they can both diagnose a low compression problem, but the leakdown tester provides a steady stream of air that can help you more easily diagnose exactly where the air is leaking. Also a compression test result can vary by the cranking speed, throttle position, etc.. and the leakdown result will be more consistent because the stream of air is regulated and always the same.
If you have an angle torque of 270 degrees, does that mean theses head bolts stretch and are one-time use? Won't refusing them allow them to break or loosen?
I love this daily boating content. Wven tho the season might be over soon, you always gotta keep up the passion!!
What about regular valve and seat lapping?
Would love to track how long that JB Weld lasts
Oh man, no digital torque wrench with angle measurement ? If you work on engines all the time it would be the first thing to buy.
Great video. What did you use to clean the surface of the block?
🇧🇷🇧🇷🇧🇷🇧🇷 falta um mecânico especializado igual a você aqui no Brasil você é 10 .
Hey bud, I’ve got a 200hp Verado 2006 and I’ve been having problems with it starting, sometimes it starts but only when it’s cold, never starts when it’s warm just cranks, I’ve been trying to fix this issue for the past year but no luck as there’s not many of these engines hear in Aus, the motor is in really good condition, I’m guessing it’s something electrical but no luck finding it.
Take the valves out every cut it and we cut the head don't fudge desk to it when I build Marine engines I tear the whole thing apart including the valves are and I read cut the valves and put it in service the head
Have you had any trouble with head gaskets sealing after using small rotary tools on the block and head to remove the old gasket material?
Great video!!!
Was it impossible to tig weld it on the spot and after that just secure it with that epoxy glue?Do you have options for some specialized machine shop to fix that head?valve seats,valve seals,grinding...i think what you did is just cosmtic.I love your chanel ,no hard feelings .And why saving someone who spend amount of fuell that cost for one weekend as someone's week sallary?Sorry for bad english.
I like the work bro 🛠️
JB Weld and send it!! How long do yu think that will last before a re-power?
Owner will likely sell it like this and not disclose the information to the new owner.
WHAT DO YOU THINK CAUSED THE HEAD GASKET TO BLOW?
Ok im an auto technician. i Have never heard of head bolts bolting the head on from the bottom of the engine.
No sir, the flywheel is up on an outboard engine, in a car, it's under the dash. His head bolts were right next to the sparkplug holes. Have a nice Day.
I also worked on car engines for 41 years.
@@keithscudder7136 watch it again. The head is bolted down from the back of the motor. 11:35.
Very interesting. Would consistently adding a decarbonizing agent to the fuel have prevented or minimized the carbon buildup on the valves and pistons?
I am following you for some time and really apreciate help from your videos. I have 2015 Verado 225 with 1000 hours, bought it with 200 hours. In few past days I felt that on idle motor shakes a bit, rpm is good, stays calm. In gear shakes a little untill gets more throttle and then normal up to 5500 rpm. When I changed spark plugs motor was in water, so when I took out 3rd plug I could hear air draught through chylinder while sea was going up and down through the leg and exhaust. Is this normal because exhaust valve is open in that moment or there should not be air through cylinder when plug is out? I felt this only on 3rd cylinder. Should I do compression or leak test? I cleaned injectors, changed plugs, all fuel filters... thanks for advices
Didn't use much quickleen to help with the carbon
I was thinking TIG weld it.
Great video as usual, what caused all of the carbon build up and what do you recommend to prevent it?
Using only ethanol free gas
Engine was run too many times under light loads. In my opinion.
Very clear and concise, thank you
And if hear air over here you know you have a trailer tire leak or if you hear a burrap over here you know billy ate a burrito for lunch.
Glade it’s not my boat well at least if they sell it you know your up for 2 motors straightaway
Mmm Picasso….I like it 😆😆😆
Ok grate sat job but I rather wait for the proper tools. I’ll pay the extra for the correct job and throw in new value seals. I don work marine engines but ok nice job
Excellent work thanks
Great job!!! How many hours did that engine had on it?
Increible,👏👏👏 fantastico video💪
when the head gasket blows, does it typically happen between the 4 and 5 cylinders? great video!
Why don't you have it on a work table.
Why not find the spring compressor?
Love the videos.
When I replace a head gasket on a car, its pretty standard for me to have the head at least decked so make sure its flat. Is that not needed on marine engines for one reason or another?
Should have been done yes. But by the looks of that mid section and what he was saying in the video they're just sending it as is and admits it's junk
@@gearwrench1davis392 thanks for the info!
It doesn’t matter if he admits it’s junk it’s a lot of time and labor for a measly two to $300 could’ve got it decked new valve guide seals and rebuilt a much more dependable engine that would last a lot longer and perform better
Yeah not worth it to skip this step IMO unless you've AT LEAST verified the head is straight with a machinists straight edge and a feeler gauge. Even Jegs and Summit sell an acceptable straight edge for less than 1 hour labor time at any marina. Not sure why they don't have one and where their valve spring compressor is either. Would've been simple to pull the valves with a compressor like normal, and they're cheap as ever and a BASIC tool that every shop I've ever worked in has multiple varieties/ styles of. I've personally turned wrenches for 25+ years in everything from indies, to the stealerships and finally my own fab/ race prep shop. I send all my heads off to be checked. Its cheap insurance, and when its a customer job you don't want an embarrassing comeback. I wouldn't gamble with what you can't see. Magnaflux can expose failures that the naked eye can easily miss and it isn't always necessary but checking a head for trueness absolutely is, especially when there is a chance it was ran hot. Too hot for too long= damn good chance there's warpage at minimum then you can have the head milled if still within spec and all those hours aren't done for nothing, only to have to tear this thing down all over again. Granted these outboards are SIMPLE compared to what I'm used to working on, not only in overall design, but packaging in general. The coolant passages on the block are also FILTHY and severely restricted which creates hot spots and can cause all kinds of erratic temps. Just some observations.
why not swap out the adapter plate from the junk engine?
I have a dinosaur 1986 Mercury black max 150 hp two stroke. I can't even believe this thing is still running 😂 and the compression is still up there close to original when new. I suspect the top end was redone. On the left bank of cylinders there's a white part number written with an indelible white ink. Anyway this thing is a beast on my 19' CC. It's so loud though all you hear is exhaust notes and typical slight vibration of a two stroke. About all I can really focus on is the sound at start up and idle smoothness as well as WOT smoothness. I don't care though I love old two strokes and you can't even come close to the power to weight ratios with a expensive new 4 stroke. Plus whose going to keep the mosquitoes down if we get rid of all the two strokes 😂
😂😂😂
The jb weld channel lol 😆 I enjoyed the video though!!
Great video !!! How many hrs on those units and what caused the carbon build up ? Dirty fuel or too much idle time and heat ?
Toward the end of the video you can see 1822 hours on the gauge, I was wondering the same thing.
I'm not very mechanically inclined so, no, I did not know how to listen for air. But, I do now !
? I have a 2004 250 salt water series can’t get rpm over 4400
New prop temp fine plugs good runs smooth as silk only thing haven’t trim is making a noise when I try to put engine down under load rpm with no load runs up to limit help please
Love your channel wish had some good mechanics up north like u they just like to replace everything till they do or don’t find problem at your expense lol
Do you have a video on how to remove seized screws on a fuel tank sending unit plastic tank how to remove them
This be good medicine my friend
