- I have a 1994 Suzuki 115 2-stroke that left me stranded on the river because it wouldn't run. Here's what i did & how i did it for under $10. It's a very easy DIY project that mostly anyone can do without paying those expensive mechanic bills. I'm happy to answer any questions if something was missed in the video. As always thanks for watching.
I have a mariner 60 hp 2 stroke triple carb....
Literally did this today !
And it's up and running again !
Can't thank you enuff for this video sir !
Will be back out on the water tomorrow! Again thank you for making this video ! 👏👏👏👏👏👏

A word of advice if I may: Please change your gray fuel line to black, these gray ones have an inner lining that sheds over time. Also try cleaning up your fuel tank and carbs( copper wire for the holes and carb cleaner +pressurized air). Believe me it s worth your time. All the best from Vodice, Croatia
I agree 100%. I've done carbs, and ordered hose since video.
@@freshwaterfiend6268
Where did you get the black fuel hose? Thanks
@@gohanalmonte573 auto zone tell them u need fuel line universal 3/8
Have you checked your vacuum and supply on the low pressure fuel pump?
How much seafoam did you use? Is it for marine use ?
That’s true what one said about the gray line and I have own 8 two strokes and 3 4 strokes every year I get rid of the old gas and put in new a I use a good two stroke oil for what ever motor you have and I put seafoam in the gas tank and change fuel filter in them and they never let me down
Thanks for your time,it was very useful. I'm having firing problems with my Mercury 400. I'm a good auto mechanic but never touched a marine engine until now. But learning quickly! Thanks again
You’re a legend! I have a 50hp Merc that’s giving me very similar issues. I bought the boat off an old guy who did a lot of trout fishing and I suspect he did a lot of slow speed trolling, so I’m hoping the motor is just carboned up. I just ordered a can of that seafoam to give it a try. (It’s hard to get here in Australia). Wish me luck!
How’d ya go mate ?
@@frankfallujah4113 well, turns out I have zero compression in the bottom cylinder :( I think the lower crankcase seal failed and let moisture into the cylinder. I suspect it leaned out and failed. I actually picked up another engine the same that had a siezed gearbox, so I’m in the process of swapping the power heads over. I will be replacing the lower seal before I put it back together 😂
Yamaha ring free is great stuff for that
Quicksilver power tune, spray it, fog it out, crank it an hour later. Great stuff
Dude. I bought a 1998 Nitro with a 115 Tracker by Merc. Hadn’t ran in two years. Was taken home and parked and left for dead. I changed lower unit oil and spark plugs. Emptied old gas. Put in fresh and added sea foam. Followed your method with the carb cleaner and after about 30 minutes I had it purring. I found that a big help was to press the key in when it started to cut off and that was the trick to keep it running long enough to clean itself out. Really appreciate the vid. Steve in NC.
That's awesome. 👍🏻👊🏻
Nc here buddy
Outboards for ya.. i got an old 79 evinrude 100hp and if you arent smelling gas the whole time while youre on the boat than it aint gonna run.. ive resinked the carbs, cleaned the thing inside and out, rebuilt the fuel pump, and all but that motor just likes to spit gas out the carbs... starts first. Rip almost every time except after winter for that start.. i like using an atf mix in the 50:1 every couple of years, seems to keep it clean.. or some rotella / diesel oil.. no less than 50:1 though..
Maybe...just maybe.. if fuel is coming out of your carbs, you MIGHT want to check the reed valves. IMHO
Awesome video. Thanks for posting. We don’t send anything to the shop, we do it ourselves…love it!
Where u were spraying the carb cleaner, what’s that location, looked to be where spark plugs are located, but normally on other side? Great video!
I like your outlook. Exactly the same as mine. It's amazing what can be accomplished with Gumout, Seafoam, and carb cleaner.
Great presentation my brother! I just experienced this same thing today. Going back to the marina tomorrow and try what you just did. Thank you so much ❤❤🎉
Never use carb or brake cleaner to start a 2t. You're washing the cylinder walls down and greatly decreasing the life of rings an bearings. Get yourself a good quality spray bottle and use premix to squirt into the carbs.
I'm like yourself. Rather do it myself than pay a mechanic. I do have a reasonable history working on all types of motors and it's good to see guys like yourself giving it a crack. Now I'm from down under in Australia and we use to just run straight water through the motor down the carbie throat and watch the crap come out of the exhaust on our cars. I've never tried it on an outboard.
Cool video. I think I have same issue 2003 Johnson 115.
From Australia.
Just bought a 2 stroke second hand 2005 15 hp 2 stroke Yamaha It starts OK but at idle runs a bit lumpy, can' t wait to try your tip as I was charged 500 dollars for my 4 hp Yamaha single cylinder impeller and tune up. in contrast I have my 2004 Mercedes Benz 6 cylinder tune up air con filer oil filer and oil change? it cost $470, Go figure - I'm with you brother learn by doing.and save big time.
Wow, dry water pump= no more water pump paddles=replace water pump because you didn't hook up any water to it.
Take spark plug out, clean it, syringe gasoline into combustion chamber with no oil in gas, remove all old gasoline, put new in, slow pull start 10 to 15 times, open air intake, pump butane in whilst another person pull starts it. You have to run 2 strokes once every ten days or gasoline in combustion chamber evaporates leaving reconstituted sludgy oil in there, hence you need to syringe no oil gasoline into it.
man those fuel issues are a bitch. 04 yamaha 50 2 stroke has a prime starter electric choke deal that is a dog. and oil injection seems to be way too complicated than just pre mixing. but looks like you got it figured out with that work you did. peace from grove, oklahoma.
Just got a mercury 15hp did the same thing and shes purring like a kitten now!!
Did the same thing on my force120 and it solved my issues. Thanks!
Just now saw your video....outstanding logic there Mate....just bought a Nissan 9.9hp 2 stroke that hasn't been run for over 6 years and I'm gonna add a can of seaform in the first tank of gas and see what the water looks like coming out after she starts up. I pulled the carb and cleaned it, new fuel pump, Impeller, and spark plugs....Hope mine goes as good as yours....and thank you for the time to make the video....
Helped a lot having same trouble with my mercury 25hp gonna try this
Helpful video man. I just inherited a little Mako 171 ‘94 with a mercury outboard. Going to try clean the carbs and follow your lead here too. Thanks man, love your attitude
Good luck with the Mako.. Nothing better than working on your own boat, and getting to know everything about it. You'll have alot more appreciation for it. More videos coming if i ever get enough time off to edit them.
Great boat my brother has same one
old gas will kill a motor clean the tank and get new filter every couple years
I am in the middle of getting a mercury 40 hp two stroke motor starting. I bought the starter and solenoid today after watching videos and talking to an outboard mechanic. Like you I don't want to take it to a shop and spend a lot to get this motor running. Plus this will give me some knowledge on my boat motor for future problems. I like watching videos where others can fix or solve a problem that could help me in the future. Keep up the good work I will subscribe and watch more of your home fix videos and outdoor fishing exploits.
Enjoyed the video. I need to do the same to mine,it’s also been sitting for a while and I couldn’t get it to keep running when I tried. You gave me some good ideas to try. Thanks
Thank you so much for sharing this! I'm having trouble getting my Merc 150 EFI started. It ran great two days ago, but when I cut it off, no start again! Glad I was back at the dock when it decided not to start again! It's done this before. Last trip to the shop cost me $500, and this is what I got for it! No more! I'm going to follow your lead! Will let you know how it comes out! Thanks a bunch!
How did it go
@@danroos1002🇺🇸1992 55 hp yamaha,has sat 2 years wont start unless i use starting fluid then runs but idles ruff. Im fixn to get some seafoam tmrw and try this,i will let u know how it goes tmrw after im done!🇺🇸
@@danroos1002🇺🇸ok did the 15 on 15 off till ran through 1 gal. Just went out 2 1/2 hours later and it started. It hasnt done that at all. Tomorrow will be the real test,have good night!🇺🇸
Great video going to try this 😊
Just clean the carb like a grown up…
filter
Good work man! I can tell its a Suzuki, just love them. Now I have 2 DT140 2000-2001 double injected , which is similar to my DT225, 94, still runs like new and very easy on gas.
Nice job, I've got a 2 stroke Yamaha with the same hard start issue... I'm gonna try this...
Hey that's the best way to do it man learn how to do it
I have an evinrude 200 xp that has been sitting and im having isues with it not wanting to idle in the water. Have a feeling this what you did might help it.. How much sea foam do you recommend using per gallon. And thanks for your video hopefully it will help
Get one gallon of gas and add one regular sea foam bottle like shown in the video and run that gallon + that sea foam you added at full speed then mid range to idle and repeat. Until that gas is gone. Should clean out your carbs. Because In your carbs you have an idling pin a mid range pin and a wide open pin your idling pin might be clogged. Hope this helps
@@corbangillen2099 hey thank you sir I appreciate it. I will let you know
This might be a stupid question but the gallon gas you put the sea foam in does it need the 2 cycle engine oil it like you would be running normally or is it just gas and sea foam mixture ?
Definitely want to add the oil same as always. Hope it helps
Yes you do have a clogged yet make sure you do not take it out and try to flag it because you will burn a hole in the piston was not getting proper fuel to the piston able to just get too hot the other cylinders will work fine but that one will burn a hole right through your pistol be very careful
quick tip if needing starting fluid for a 2 stroke... put mixed gas in spray bottle and use that so you don't cook the top end. If stuck, spray penetrating oil first and then the starting fluid.
Thanks for the helpful vid mate👍
I’m having issues with my boat here in nz 😂 thanks brother for the video.
It's a never ending cycle with all boats, especially 2 strokes
good wideo thanx.
Like your video. I bought a new 90 hp 02 mercury 2 stroke still runs great. I had gray fuel lines on it and they came apart inside an found the way to the carbs. I took them apart and cleaned them. Runs great. I have a 16’ Lowe bass boat but I catfish only It will run about 40 mph. I have about 250 hours on the motor. I run a 12 3/4 - 21 aluminum prop. Take Care and God Bless from Hartford Ky
For your hot soak dud you use 1 can of sea foam to a gal of gas? Did you leave your oil mix at 50:1? I have twin Johnson 175's that don't like to idle all the time. Have rebuild all 6 carbs on one of the engines it helped but didn't completely cure it. I'm wondering if the Reed valves might be gummed up too. Boat set for about a year before I got it.
This is wishful thinking that this magic repair will fix problem - when you run this at speed + load there is a good chance motor will lean out + poss seize as any restriction in carbs (jets / fuel circuits etc can have varnish build up) may not supply fuel requirements. I would be afraid to run like this - do it the right way + remove carbs / fuel pump clean + blow out everything! Power heads or rebuilds are not cheap!
Hey just wondering what size motor that is? Just bought a bass boat with a 85hp Suzuki , got crank but won’t fire have spark and compression next is the fuel to check any other ideas thanks
Thanks brother I'm troubke shooting my 65 🐴 mercury even if it doesn't work appreciate u posting this I'm in the same boat when it c comes to doing it myself u have a new subscriber good luck and God bless (Rockwood Michigan)
Suscribed and gave ya a thumbs up. Ive been doing this to my 3 motorcycles for the past 23 years and use seafoam in my 2001 F150 as well. Every spring I put a half bottle in my motorcycles, then repeat in 3 months. In the truck use a half bottle in the spring and then in the winter to do the same.
Just bought a Tracker DeepV 17 with a Mariner 60HP 2 stroker, all vintage 1995. It runs good now cause the owner replaced plugs, impeller, etc.. but I plan to add seafoam to my first full tank of gas when I pick the boat up this weekend coming and will replace the fuel lines to black. Thanks again for the demo. I havent owned a boat since 73 to 1978 so I forgot what I knew about the outboards! LOL
Great video, I have a 1990 115 mercury, unlike yours in this video, mine was running just find and went out a couple of weeks ago and it turned over but wouldn't start was out the weekend before do you have any suggestions?
Hey bud just a follow up from canada here. So I took out the 14ft fishing boat with a 25hp older 1986 mercury 2 stroke outboard . I fiddled with the screws and choke stuff ect before going on the trip and got to get it to start pretty good as I had previosly installed electric a starter ect ( cant pull on the cord to much anymore AGE you know what I mean )anyway up on the lake same kind of thing again, had to keep cranking with the starter to get it to fire up, when it did and got warmed up ,it ran like a bird, following day same thing lots of cranking then ran like a bird, its a 1986 but looks brand new Ive had it for 30yrs but hardly used it , now retired I use it more often, there cant be too much wrong with it as I mentioned it looks brand new, so I plan to try your method of cleaning with the gum out and sea foam hope it helps thanks for your time to share the info
My Mercury is doing the same thing as yours was. I am going to give this a try and hope it works for mine. Thanks for the video.
any update
@@StarKillersSon took it to the shop, no luck with it
Good one yall, that's what we do here in GEORGIA if broke we fix but glad u got it running
Need to do the same to mine. Compression good , spark excellent,fuel no good.I cleaned out the fuel tank and added new premixed fuel , cleaned out the carbs and checked out the fuel pump.She now runs good, with no issues.
Run some quicksilver quickleen in the gas its amazing stuff!
Seafoam is an amazing product I use it to stabilize my fuel.
Replacing the control box with a new one on a 1978 Johnson seahorse 115hp
I love the video Brother! You definitely got a sub from me. Keep up the good work 👏
U remind me of myself thanks very much for your information. Roger
now treat it with a can of Evinrude or Quicksilver powertune, that thing would run like new!
What was that that you were spraying that fluid into? Did you take off the fuel rails?
the seafoam will make it smoke thats the process of cleaning the junk out
n Suzuki's are good motors to though I dont see a lot of them in my area more common in oregon n Washington
Sounds like it's missing pull one plug wire off and see which cyl is not firing at idle
This video is very informative. I have a 40 hp Yamaha 2 stroke. I think this will help me since my motor was acting just like yours. Keep up the good work!
Don’t use auto fuel line .use marine fuel line it’s thicker.
Oo
Thanks for the tips might do this to my new boat purchase
Went from a drunk man yelling at himself in an alley to purring like a kitten.
Sea foam is in every tank of my gas good insurance
And also them grey fuel lines tend to get plugged a lot as well n need to be replaced
Never mind I actually got to watch the rest of video great job brotherman!
Yep that stuff does wonders I put a can of it with every few fill up and that helps keep your carbs clean also you can get a clear fuel line now not black where you can see your fuel and see what's going on with it one other thing I might add is it doesn't look like you have a ground on your fuel tank to the fuel fill cat very important enjoy the video
Did you add the whole bottle of seafoam to that 1 gallon?
Good stuff mate, this video saved me some money 💰
Keep the videos coming.

Check compression on all cylinders
What was actually the problem ?
Great video friend I just bought me my first project boat and I will definitely need your expertise
burning too much oil ....fuel filter
You hit on the spot . Mine wont start , been sitting.
Wow wonderful ❤️🥰🥰🥰💞💞🥰💞🥰
Nice, I do the same, my wife is the breaker I'm the fixer. I need a vacation. So I'm getting a 250xb with low compression on 1 cylinder and going to spend some time in the shop. LMAO
Shop time, and solo fishing/hunting are some of the best times. Just can't admit that to loudly. Lol
Thank you very much I'm having the exact same issues with my Yamaha 225. I'm going to try your fix this weekend I had a feeling it was something to do with the injectors or a dirty fuel system. I will give an update if this fixes it thank you
Did it solve the issue?
Great to know I can try this
What brand engine and boat is this? I’m having the same issue with a 1999 Nitro 884 with a Mercury 150
It's a Suzuki DT115. Sometimes after a good cleaning the carbs need to be synced back up. They get just a hair out of tune.
I saw your video, I have faith it's going to help me cus my Johnson sounds just as bad and did the sa as your mercury.i will try it myself n hope it works on mine.thank you I will keep you posted.
Did you try this method? I have a Johnson as well that has the same issue. Wondering if it helped.
Well how did it do after sitting a few days?
How do you hot soap the outboard motor?
Good for you. That will Work.
Why does it work when you are spraying carb cleaner into the carburettor? Is it because it cleans something making fuel available for the carburettor? Or is it because the engine can actually run on carburettor cleaner?
The carb cleaner is combustible like fuel. Spraying it into the air intake serves as a fuel delivery when the carbs are failing to do so. It's a good testing tool for engines to determine a "no start" from lack of fuel or spark. If an engine briefly busts off from carb cleaner, it's an indicator that it's a fuel related issue. If it won't briefly bust off, it's most likely a spark/electrical problem because nothing is igniting the fuel. It can get deeper than that, but that's a basic rundown. 😁
I think you got it. Sounds good to me
As far as mechanic in a can goes, that stuff is as good as it gets.
You don't know how to use the choke
Hi from Australia 🇦🇺
You are full of faith. I like that!! S. Idaho here!
U need to put some automotive fuel line on it cause that gray line you have on there now have a clear lining inside of it and it will collapse and make your motor starve for gas
I changed the fuel line to that auto line and it crunk on the third or fourth pull
Kool
or run ethanol free gas and the gray line will be fine
@@devinmoore6412 people blame that gray fuel line, the truth is don't run ethanol gas and you won't have a problem
I use non ethanol gas only.
Need to try the hot soak trick
Thanks for sharing
I like it!!! Really helped me out. Thank you.
Glad it helped.
This offers some insight. I had mine in the shop a few weeks ago- got to the boat ramp....and nothing. The guy that worked on it said it would start hard....but this was ridiculous. So this weekend, going to try this, along with some fresh gas. The gas that I have in there is a mixture from last fall, and January before I drove it home from my Father-in-Laws house. We've never had issues with this motor not starting- always started on first crank for 20 years. Great engine.....but we're perplexed after having it professionally tuned up and having the carb rebuilt.
Throw away all of the old gas and start fresh
@@nateroot Took it to another shop- ended up being that the idle was set too low on the carb. They got it set right, the motor starts/runs better than I've heard it run in years, lol.
Wow!😊
Glad for this videeo...I have a susuki 30hp on my little flat bottom and its been cutting off during idle, once it going it runs liek a dream but the idle kills it. Will try this treatemtns!
Did that work? Cause I have the same thing happening.
@@Fishermattmatt93 been traveling these few weeks...gonna do it when i get home
I have a older Mariner 2 stroke 40HP. Would only run with high idle switch up. Turn it off it would die. Came home used a full can of seafoam. Now runs great at idle and wide open.
@@Fishermattmatt93 so far works, I. Also gonna put a new water pump too
@@inked4011 Ive got a 1986 Mariner 150, been sitting a couple years. Was my father in laws. He used to put seafoam in it every year. I kinda forgot about it and now the fuel pick up is missing. Guess Im gonna dump the tanks & start fresh.
Gray line is for ethanol
Gray line may be for "above deck" use. There's black line made for "below deck."
However, I don't know for certain that all manufacturers follow that scheme.
I hate that!
