***ABOUT THIS VIDEO:
The problem I experienced this summer was my Mercury outboard run then dies.
It all began when I launched the boat for the first time this summer. I headed out on the lake for a morning of pike fishing.
All was going well when we decided to move to another spot on the lake to fish. I was running the boat at 3/4 throttle when all of a sudden the outboard motor starts bogging.
I shut the motor down, check the fuel and the ball. Everything seemed fine. I started to boat back up and it ran great, but only for 500 feet and bogged back down.
I thought it was maybe the impeller that transfers water through the boat motor for cooling. Changed the impeller and nothing changed.
After some research, I read in a forum to check the fuel line before going deep into the engine and seeing a mechanic.
I changed the fuel line, fuel tank and fuel filter and my boat is running top notch again!

Watch PART 2 of Mercury Outboard Runs Then Dies as I show you where the second fuel filter is located and how to remove it: ruclips.net/video/3YKp9NHQtXs/видео.html 👍
Aloha from Hilo Hawaii. I have a 40 hp mercury on my 13'whaler. My problem is that the engine just immediately shuts off. No chugging, no out of gas feeling, it is just like someone threw a switch. My mercury authorized mechanic has replaced ALL THE STUFF, you did and it still keeps shutting off. It won't restart for about 10-15 minutes, then it will do it again. Any other thoughts?
Thanks
helped a ton...thanks!!!
Hi, i replaced my solenoid which now the outboard starts and runs but after thr first trip the starter motor stuck on constantly trying to Start the engine without the key in so i had to disconnect the power wire from the starter motor which goes to the solenoid. This happened 26 miles out at sea but i managed to get the engine started by putting the live wire back on the starter motor and turning the key quickly then disconnect the live wire on the starter motor to stop the starter motor from spinning. Any ideas why? Sorry for the extremely large comment/question
I have a 2017 Yamaha 40hp on. Bought it with 74hrs on it...now has 116. I'm running strong, then idels in a no wake zone for about 15 minutes...stalls!!! Took me almost 20 minutes to restart. Took it back to dealer...changes fuel filter, runs a fishing line through where the water port exits.
All good for a couple outings....and once again, idels in a no wake zone...then stalls. This time 45 minutes. Periatic pumping the bulb... frustrated...I put out the orange flag ..5 minutes later...one last pump. It starts.. ran for about 400 yards....stalled!!!. One more pump ...it starts...made it back to the docks about 2 miles.
Got some seafoam marina fuel additive...ran it for about an hour. No issues.
Not sure if it's a fix or not being the day before..it ran normal on our way back.... frustrated!
@@tracylewis9796 ever find the issue?
I use black automotive fuel line and I wont have that problem ever again. Reuse your connectors with hose clamps & there's not a inner liner inside the black automotive fuel line to break down & it's cheap. Good luck 👍
I did that also to allow for ethanol fuel occasionally
Just invested in my first small boat here in New Zealand and came across your video. It has helped alot and provided insight into how an outboard works after ageing time. Thank you again
Massive thanks from New Zealand mate! Fixed my entire issue and subsequently saved me so much money. Such a clear and informative video, thank you so much!
Roland great info. I had a boat that the water pump impella was bad and caused the problem you talked about. I am sure you help several people on this one. A+ brother
I'm glad you found it. Sometimes it will get by the filter and get caught up in the screen for the fuel pump or in the fuel pump. And it can create the same kind of havoc blocking passage of the fuel and random fashion which is always difficult to figure out
Thanks for sharing your experience with us.
I will check my fuel filter today along with fuel lines.
Hi mate, you have described precisely the problems I am having…can’t wait to get the new fuel line on and check out that filter too. 👍🏻
Wow! I had the exact same problem about 4 years ago with my 60hp Mercury FourStroke outboard. I did everything you did here, except I also changed the other fuel filter, rebuilt the entire VST, and replaced the fuel pump. I had a mechanic tell me over the phone that the gas line I had was designed to work with MTBE (a fuel additive that was replaced by ethanol in 2007), but not with the ethanol additive. The new fuel line and bulb I bought had a tag on it that said it was made for gasoline with an ethanol additive. It worked.
By the way, I have driven from Colorado to mid-Saskatchewan every year for 20 straight years to catch pickerel, Jack fish, and lake trout. We quit about 3 years ago. I sure miss it.
Another great DIY video on the fuel filters!
A person really can save a bunch of money for basic maintenance and it's not overly complicated.
I enjoy small engine repair.
Thanks Roland!
Hey @Getting it Done North of 7,
I have an episode dropping July 28th, 2020 about my Stihl KM110R Weed Eater/Brush Cutter and the blade I have on it just for you.
I did buy another brush cutting blade from Home Depot online so come and check it out.
It will be released at 6am.
Thanks Roland! :)

Just watched your video yesterday yesterday and went and replaced gas lines today and that was the exact problem thanks for your help great video good information
Bought a early 2000 40 HP Mercury-2 stroke with auto oiler and it was rarely used by my friend and I bought it. I saw your video and checked the filters and my filter looked just like yours. I replaced it and engine started and ran and idled smoothly. This video probably saved me from breaking down on the lake. Thanks!
Great video.
I had the same issue w/my 25hp Yamaha out board & found out the liner in the fuel line collapses when I give it full throttle after running it for awhile.
So now I'm just gonna replace it w/regular fuel line & change out the fuel every yr when I store it for winter.
Excellent video. Applies essentually to all outboards as far as tanks and filters. As you state always check the tank, fuel line and filters first. Never run old gas in any motor you care about. A great old timer mechanic told me 90% of hard or no starting issues are fuel related. Also many people aren't aware of the 2nd fuel filter in most outboards.
I watched this video again because I am have similar problems again with a 25hp and you didn't really troubleshoot the problem because you changed out everything!!! I don't want to change the fuel tank if I don't have too but I will if that is the problem! I need to go step by step and figure this crap out! Thanks my friend!
Something so simple a lot of people don't look into it, thanks for the info.👍👍
Good Job, Roland. Nice information here 😉. Glad she's running good for ya now. Things breakdown so fast these days. Impellers are the LIFE of those little outboards. We've seen them come in in pieces from people who dry crank their engines 😱. I remember using old metal fuel tanks. Those things were heavy! It was a relief when they started making the plastic ones. Those newer mercs are nice! Mark loves those 😊 Great Vid!
I have a 60 mercury on my 6 year boat and I yearly change the main filter and the in-line filter every 3 years. Haven't had any problems. Good video .
This video helped me so much!!!! We had a similar 1,2,3 problem with our Tohatsu, although were in the middle of nowhere Mexico cruising on our sailboat. Our 15 hp dinghy motor was doing the same thing, then we replaced the tank and it got better, but we had to go deeper. We had a bad o ring and then clogged fuel lines past that. Thank you!!!!!
Your video is priceless and just saved me hundreds on a mechanic allegedly cleaning my carbs. Thank you for taking the time to make it!
That's awesome Mike! Glad to hear it.
I had the same problem. Changed the fuel filter and that fixed it. Glad I saw your video.
June 2, 2023. I literally just had the same problem with my 9hp. Was getting upset and actually broke the rope. But after watching this and another video on how to replace the rope I'm ready to try out your advice. Wish me luck.
Sir, thank you so much for such a comprehensive review. I’m having the same exact issue and I’m confident you just saved me several trips back and forth like you had. Take care!
You are welcome!
This was so helpful. Thank you for the detailed troubleshooting tips!! I'll be taking a look at my dad's boat as soon as I have some time.
My boat is doing the same thing. I didn't realize there was a second filter I thought the one nearest the fuel pump was the only one!! Off to go do it right!! Thank you for sharing the info.
At first I thought the fuel pickup in the tank was plugging up as I have seen that before. But the simplest and maybe cheapest next step would be the in line fuel filter. Also I have seen many situations where there is an obvious filter in the fuel line but another hidden filter too. On my 30 year old 15 HP Evinrude there is a screen on the carb (if I remember correctly) that caused me the same issue and my mechanic showed that to me. Overheating doesn’t fix itself quickly. The engine has to sit quite a while before it will run again well. Great video and thanks. I also didn’t know about the inner fuel line inside the fuel line.
Good job 👍 Outboards can be frustrating but your patience paid off. Informative video.
I don't mind trying to figure out these problems.
Tank you, you just described my entire problem. I am going to try this and I will let you know what happens.
Nice video, mate. A lot of people don't understand that a lengthy troubleshooting process like this is sometimes necessary, and walking people through every step really helps to illustrate how important it is to keep moving down the line until you fix the problem.
Your right sir, thanks 😊 some folks right
My boat had same issue. Built in fuel tank. I decided to isolate the issue by replacing the fuel line kit like you and an external new 6 gallon tank. Problem solved. Built in tank has sediment and old fuel. In process of cleaning it now. Your fix will definitely help relieve alot of headaches and wasted money. I knew your issue from the minute you said what happened. 😀 mine is also a mercury 135
Great information. Thank you for taking the time to share.
thanks for taking the time to do this
Good job. You were very clear and concise with your explanation.
Great video. I was having the same exact issue. My boat has an 11 gallon internal tank and the ball bearing that sets in were the fuel line Connects to the tank had rusted and was stuck. I knew it was something to do with the Internal tank because when I used an 5 gal
external tank the motor would run with out issue.
Well gonna go try this out. I've done everything you did and have had the exact danr problems. Hoping this fixes it.
Exact same issue…thanks for the explanation and advice ! Worked for me !
I recently bought a used Mariner 15 hp outboard. I didn’t want to spend the 4000+ dollars to buy a new one. I only have about $600 in this motor total and that is after installing a new impeller and propeller. The motor has ran well until recently. The tank is an old metal tank and I have been having the same issues as you. I suspected it might be a fuel supply issue and you have helped confirm my suspicions. I plan on doing as you have suggested. Thank you for making this video.

My tohatsu 9.9 is doing the same things. Thank you for posting I will change fuel line & filter.
Great job in finding the issue. I have the same and will do what you did to find problem. Thank you
PS: I would never run any outboard big or small without a separate water separating filter as my primary filter. You would be surprised how much condensation a fuel tank can make. I like the Ray-Cor models but Sierra and most manufacturers make their own as well. Shop around and get the appropriate size for you gallons per hour and then get a 6-8 micron paper element in the spin off portion. You mount it to the boat then hook your six gallon cruise tank (or whatever your fuel source is) up to it. It is plumbed into your motor. You can quick connect the tank to the separator to facilitate fueling or whatever. The best separators have a spin off filter and a collector bowl at the bottom where you can keep an eye on it for any water or other contamination. Some situations require a metal drain bowl, some allow the see through plastic. All have a petcock so you can drain a sample now and again. Glad to hear everything worked out.
Thank you for posting this !!!! My brother and I got a used trihaul with a mercury 70 hp 2stroke the boat had been sitting a long time we finally got it started but shuts off but before we started it we bought a new tank,fuel line, new gas and we did not even think about the filter 😳 but when it ran we heard a loud sound sounded like a grind ?? But only when it ran on hi idle but we decided just to take it to the shop and get it all redone or just get another motor but thank you for your awesome video!!!!
Great job! I'm having same issues and will try exactly what you did! I will keep you posted!
Good luck!
I currently have this issue with my Tohatsu. Thanks for the insight it was very helpful.
Thanks. I had the same problem with my last boat overheating and shutting down. Great fuel feed insight. Thanks much!
Thanks for visiting!
I have had a similar problem with my Mercury 25 2 stroke.I will check these items! Thank you for a great video!
Thanks for watching.
Excellent video your instruction was right on and I took this advice not having trouble yet but for preventive maintenance. And I'm trusting to my motor now and here in out. I know I'll use this information for years to come. I'm a subscriber but I must say your demeanor is one that grabs your attention and non distracting. Looking forward to more.
Thank you!
great info roland you nailed it always start with checking fuel first..
Sure did John. Thanks
Your video helped me to get my friends motor running great 😊
I was about to rebuild the carburetors until I watched this video. Yep it was a separated liner in the fuel line causing the problems. Thanks for bringing me back to starting with the basics.
I was about to do the same thing 😂
Great video I had the same problem during sockeye season 5 years ago. I’m my case it was the bulb.. it still felt nice and solid and sounded like it was pumping but the internals had collapsed and wasn’t allowing enough fuel through… just enough to start and idle and run for a few seconds under load then would die.
Very helpful troubleshooting video. Thank you.
Cheer's from Crow Lake ! Exact same issues ! Just tired of more $ every Summer on the tin boat ...lol Guessing a new tank and lines is my troubles. Thanks 👍
Thank you sir,, I had a similar experience with a 15 horse mercury. Have a wonderful summer.
Thank you for watching 😊
Same problem. I will try all that. Great video. Thanks
It sounds like that inner liner was a step up from the old Styrofoam liners they used at first! 😂 I had a VW long ago with a similar issue. I didn't know but the tank was rusting away on the inside and clogging the fuel lines. It caused me lots of headache until I learned what was causing it.
You helped folks today with this video Roland.
Fresh people being born everyday that need to learn everything.
Have a great day up there!
Wow I'm late seeing this one Robert. Thanks for sharing your issue.
Thanks you have described my exact problem...I'm gonna try it
Thanks that was a nice methodical way to approach this outboard problem, Now back to my engine and let me do what you did....thanks again
Replacing parts until you fix an issue is not what I would call methodical! There is a much easier and faster way to diagnose problems like this, Unfortunately I did not go to school and learn my trade to teach others for free on RUclips!
I took a small engine class when I was in high school just to get easy credit. I wish I would have paid better attention. I am very handy with my hands building things, but small engines often get me. I did change a carburetor last year and it fixed the problem - I chalked that up to a good guess versus diagnosing a problem. I generally find it is fuel related - either the fuel or the carburetor. Good video.
Get a good outboard repair manual and read it over and over ! That is how I taught myself Boat repair before Yamaha sent me to school .
Hi have got the same problem your help was much Appreciated.
I got the EXACT same problem on a 2 year old 60hp four stroke Merccury..... I’ve done the line, yesterday did the “new” remote/portable fuel tank. Ran good for 5-10 minutes and died again on what feels like fuel starvation......was going to take back to the dealer/marina (30 miles away) next week.....
Now will try fuel filter.....if it works Roland......I owe you a BEER ,..... as it saves me BIG BUCKS and more importantly....the best part of the fall fishing season. Thanks for a great video.
Did you resolve
Ethanol absolutely destroys those cheap gray marine fuel lines. Only use non ethanol and never buy gray fuel line with the clear plastic linner inside. Buy black automotive fuel line instead.
Excellent and very helpful video. I have the same issue happening with my 9.9 merc lots of inexpensive and easy to apply fixes. I will try the filter idea the next time I am up at my cottage.
Glad it helped
Valuable information, thanks for sharing…much appreciated
I have a Mercury outboard. Good information. I most likely have to to the same replacements and cleaning
Will take a look at my fuel filter now. Having a similar issue. Replaced fuel line but not the connector.
Excellent video, thank you very much for posting. Helped me a lot 👍🙂
Trying your idea this week,thanks a bunch
Thx for this - extremely helpful. I did EXACTLY the same sequence as you, including replacing the fuel line from the tank, then the tank itself, then the filters. In my case I needed to change both flters to remedy the problem. Thanks for taking the time to make and post your videos.
So hard to find a good "honest"marine dealer. This video explained the exact same symptom my Mercury 40 HP was exhibiting. Went through your process and it runs like a dream. Thank you for taking the time to teach us.
After having issues myself, I had found a plugged fuel filter. I change the filter and fuel line and drained and cleaned the fuel tank before I saw your video.
So I went out to the garage and cut my old fuel line open today and found it 85% to 90% clogged with that brown crap.
Looks like the fuel line should be on the maintenance schedule!
Good to know what the source of the problem is.
Really helpful tip for overwintering your boat. If you pick up a gallon of that trufuel period or something similar it's expensive but it's basically 98% paraffin. You won't get any of the harmful chemicals like Benzene which ends up ruining all your hoses. Then in the spring you can fire it right up
Great video. You had the luck of being able to get back each time on your venture, We have a pontoon boat, that is hard to work on when it is in water,and expensive to have someone pull us out each time it fails. We have same problem as you did but in our case all that stuff will need to be repaired/replaced. Your video will be a huge help.
Great video. I am having the same problem. Boat is 38 years old. I've had it two years. I'm betting the fuel hose is the original. Will replace it tomorrow.
Thanks
I am having that same problem now, so I will try those methods and see if that helps. Thanks!
Awesome job explaining everything, going to try a couple of these fixes on my boat👍🏻
Great video! This saved my trip this past week in Florida. Thanks so much for all the useful intel put in easy to understand step by step instruction. Greta job! Thanks
Hi there, glad to hear that. What exactly was wrong with yours? Which part helped?
@@GettingItDoneNorthOf7
Based on the advice in the video I changed both fuel filters and the fuel line from the top of the tank to the motor and replaced the bulb. We also removed the old gas from the tank and replaced it with ethanol free fuel. All told the cost was about 125 for the parts and my son and I made the changes. The job was easy with your help and for that I am eternally grateful. Thanks much my friend!
👍glad you fixed the boat Dad. Now we can go fishing and swimming.
That's the plan!
Great job explaining your challenge. I have a similar problem and will follow your lead.
Thanks
Craig
I have the exact same symptoms with my outboard motor, thanks for this video, God bless you.
Good luck with your repair.
Thanks for sharing this video. Really appreciate it! Cheers! 😊
excelente explicación, tenias dudas par ael cambio de filtro 👍
Well I don't know about about Boat Mechanics I know more about cars which is more than I want to admit cause I don't want to do it, you had a great video on explaining and demonstrating Roland!
Great Video, it was very well explained. Thanks.
I just escaped the everglades. Even my 3,5 back up engine failed. Low engine oil shut off.
wtf.I never had to use it before You sound right on about this .Same fuel hose degradation.
A cheap quick fix is rare these days. thank you
Thank you sir for the video I'm ready to go work on mine and get my problem solved
Very easy to follow...Thanks!
I'm so happy to have found you, you have the same motor as me so this is extremly helpful thank you!!
Glad I could help!
Just when you thought you had it fixed, you get kicked in the berries. I'm glad you got it fixed, and thanks for sharing.
Yes the poor berries. 🤣
I'm on year 3 and experienced the same issues. Tried changing fuel doesn't work same issues. Going to try new filter tomorrow. Thanks for your video
Fantastic, thanks for this video. This is a huge help.
I will now go and change filter as my 25go merc is doing the same .cheers mate
Great video to help with those stubborn intermittent issues. FYI the plastic ties on the fuel lines are not necessarily your average every day cable ties. Technically there are special fuel line cable ties that have a "shaped" lock end that is curved to maintain contact pressure a full 360 degrees around the line to avoid fuel leaks. They are known as radius zip ties or radius cable ties.
Never knew about this. Very cool
I used regular also -- where can you find those? --- ah googled them and found them on amazon ordered, you'd think mercury would put them in the kit, oh well I had to get a hundred so ill be for for the next 50 years or so....... thanks again I did not know about those
Thanks for the info, I just bought my mercury outboard, nice video. tom
Glad this worked for you. I had same problem in Manitoba but for me it was moisture in the gas from leaving the gas tank vent open in the rain.
The moisture would plug the jets in the carb.
Fix:put 1oz isopropyl alcohol in full tank of gas(or replace gas), tilt motor up in lock position, prime bulb until gas come out of carburetor throat and use a water absorbing insert in tank(made for snowmobiles)and that should solve another issue that can cause this same problem.
But yes, pay attention to the breakdown of fuel lines and you fuel filters.
Good info for newbies like me. Have had my boat just about a year now, and learning lots. Just subscribed, looking forward to watching more of your videos. I'm in Phuket, Thailand. If you ever pass through, give me a shout and we'll go for a spin.
Great vidio i had the same proublem with my fuel line linner was all broken up i bought some automotive fuel line gonna see how that works this summer
Thank you very much, I had the same problem with my engine and I didn't understand what it was, the tank was clean, the filter was dirty. I will replace the tube as soon as I can. God bless you, greetings from Italy.
You're welcome!
Thanks a bunch man.. I had this problem yesterday on the lake.. didn't know where to start
Great hope you get it figured out.
Great video, sometimes you gotta start with the simple things. I always drain the gas out of the fuel hose over the winter, so no old gas is sitting in it all winter long. Hose is 24 years old, so far good. I also now always use Super non ethanol gas in my boat, lawn mower and snowblower. (and one car that doesn't get driven often)
Thanks so much, this was exceptionally good for me and may solve my Robles as well … Thanks so much…
Great video, you explained everything very well. Thanks.
Thanks I'm glad it helped you.
