- How-To-In-A-Few video on cleaning the carburetors on an outboard boat motor. Get that engine running smoothly and starting on the first crank! Both spraying a solvent cleaner and running it through the motor are featured.
Dude you need a camera man or woman
Non-ethanol fuel is key to not having to do carbs much or ever. I have a 92 Evinrude and just did them for the for the first time.
Assuming it's a two stroke... I would swap out the plugs, mix up a batch/tank of two stroke fuel and buy a can of spray "outboard" starting fluid. The primer bulb should firm up after pumping. Make sure you have a good battery or strong pulling arm and let it rip. If it doesn't atleast try to fire up after a few attempts. Spray a little starting fluid into the opening of the carbs. Not too much, since you don't want to flood the engine. Don't rev it up until it has been running a little while.
your method worked on my 01 champion bass boat,, ive owned it for just 2 yrs and its never ran better,, a quick bumb and shes purring,, it sat at the body shop for 9 long months , now shes running great ,, thank you so much sir....
Great video, it really helped with my outboard, thanks!
(you might want to edit out that quote: "And now I'm squeezing the ball and it's slowly getting harder," though lol).
Lmao
Even if I am going to use the boat again in a week or so I always unhook the fuel line and run the engine until it stops. That way there is No fuel in the carbs to gunk up. Same thing in my Weed Eater or any 2 cycle motor. Takes a little time to Restart but It will every time and no expensive return visits to the boat Shop.
Actually, it will always remain fuel in the bottom carb cups if you dont unscrew the drain screw at the bottom of your carbs. This will eventually clog your carbs! Just a tip!
Hey man, thank you for this video. I bought a '93 Four Winns with original Johnson 115 2-stroke oil injected outboard, and had been having idling problems with it since day 1. I came across your demo here, and decided to give it a shot. I'm by no means an enlightened mechanic, but found this video informing enough to take care of my problem. I also installed one of those fuel selector valves because I think it's a great idea. Also, thanks for the info about letting the engine run out of gas if I'm not going to use it for again in less that a week's time. My engine did die on the cleaner/gas mixture a couple times at the very beginning, but I think it just needed to pass that gunk through and warm up a little bit. Because she is purring like a lion now. Thanks again. Great video. Screw the a$$hole$ that complained about the camera work. This video was enough to save my fall St. Croix river run I had planned.
Did you like that boat?
@@Ravens657 loved it. We ended up trading it in for a pontoon later on, then eventually sold the pontoon to help fund our wedding. Now we are boatless. :(
Maybe again someday. It was fun when the kid was younger and more interested. Now he just wants to hang out with friends and play around on his phone…. Kids these days.
I agree. Spraying into the carb will lean out the oil a little. But while running off the carb clearner fuel mix, the VRO was steadily delivering the correct oil ratio to the engine.
I know this is an old video, but, thanks man. My '98 115 evinrude had sat up for 7 months, and when I finally got it back on the water, it was only on 3 cylinders. I threw a couple of fixes at it all at once - plugs, new primer bulb, cleaned fuel filter, and this trick with spraying the idle circuit jets. I'm not 100% sure which of these, or a combination of them, worked, but it fired off on the first bump of the key. Ran all day with it, and everything was great - so thanks.
Worked great on my 2004 Johnson 90hp saved me from bringing it to get the carbs rebuilt thanks!
Thanks for the video. I have a 2003 90hp Bombardier Johnson. Same setup just the V4. This worked great and saved me a lot of money.
And you are goin way over on your RPMs... you can't do dat boy ! Anything over 1800 RPMs is to much out da water ! I don't care what day told ya... don't do dat ! You gonna tear it cher '
Love it! Thanks cher!
5:16 See the white fitting with the fuel line attached to it right in the center? That's a fuel screen/filter. Unscrew that and take a look at it while you're doing this. Should always just be hand tight. If its tighter than that, make sure to only put back on about 1/8 of a turn past hand tight when reinstalling. Those are often the culprits. They'll be black inside the screen when dirty. I suppose you can clean them in a pinch, but I always keep a couple of them handy and just replace them. Those are usually a bigger problem than the carbs.
Just make sure to always have the correct oil mixture. Several people did not understand that this engine pumps the oil automatically from a separate oil tank. One should never run a two stroke engine without the correct mixture of oil in the fuel.
My 89 90HP Evinrude Motor with similar problem. It will start up and rev up but as soon as you engage the propeller it dies. Should trying your method help fix the problem. Also sometimes it wont reach full speed it will be at full throttle but only going half speed. Thanks your video was help full.
Hi, I have a similar Motor (225) like you have ! When you look between the carburetors, there is this red square with a gray cap on . Remove the cap, and you see a valve Stem just like from a tire ! Just blow some air through this valve with a compressor, and it will blow all dirt out of your carburetor ! Than mix one can of SeaFoam with one gallon ethanol free gas , run it through your motor ! This will clean the jets and take care of carbon build up ! This saved my past weekend !
the filming sucks
Seafoam is good to de-carbon a two stroke engine... but this was B-12 Berryman Chemtool Cleaner.
Check the autoparts stores. I use Berryman Chemtool B12
Some good info, but on a two stroke, you might want to manual clean carbs as if a cylinder is not getting the right mix of oil and fuel you can score the dry cylinder and do huge amount of damage. just a note. Good video!
TIP! I use the exec 100 XD oil on my 1998 johnson 150 and no smoke at all.
I'm thinking tripod. Felt like I'd been on a circus ride
should not rev an outboard unless under load...check owners manual
Need a camera person
Heads up first check the filter to the fuel pump assembly right there in the front..middle..when you disessemble it its is shaped like a cone.Also you should replace your fuel water separator..maybe the illustrator already did this..But that should be your first course of action..And its relatively inexpensive..start simple first...then move on...I have a four year degree in marine mechanics guys...make sure you got a clean non restrictive fuel flow first.Fuel primer bulbs screw up too...If your running with a vro disconnected and mixing your own fuel This video is not for you..His oil injection system is operational...so you wont lean out and blow up your engine.
also no needle valves..These carbs have oraphaces..tiny brass screws that have a certain size hole for flow ...They are your high speed jets..lower ones in carbs.easy to remove with skinny screw driver...clean and reinstall...Power tune and fogger was designed for proper maintance so you can avoid this.
michael, I've got an old two stroke outboard that i could get to turn over two weeks ago and idle, but after sitting for two weeks now won't catch. do you think it could be sticking valves/venturi in the carbs? nothing else changed.... or could the gas (with stabilizer) in it have gone bad that quickly?
Make sure you still have spark...harbor freight sells spark testers cheap..few bucks...then check your plugs..are they wet or dry? Does the gas smell stale if they are wet..The info I stated above was specific to that series and models..that have high speed orafices.I have seen the foam from the cowlings (engine covers) disengrate and get sucked up into the carbs and end up in the orafices..Start always by making sure you have gas getting to the plugs and good spark.go from there..If an engine has been sitting for a long time..yrs...not just months changing the fuel pump is usually indicated too.....
I'm thinking a carb cleanup is necessary. the foam lining did get chewed up recently, that would explain the fuel/foam coming back out of the choke plate.... I replaced the plugs (old ones were wet) and have a clean blue spark now, but still no catch. I'm hoping a carb rebuild does it; gotta love the "free boat"....
So I got a 99 Johnson 115… ur saying they have no needle valves at all?
If it's choked and not trying the fire up after 5 to 6 pulls... I would squirt a little in. I would also definitely change the lower unit oil before using the motor. Walmart sells a Pennzoil quart with a handy pump to fill it bottom up. After that you can just use regular 80/90 gear oil. I need to make a video of that too! LOL
@bigdaddygato Yes you could try that; but that would be pretty strong, and you want it to run awhile.. it needs time to work. I think I used about a 3 part gas to 1 part cleaner. Just realize that this motor is a two stroke and requires oil to be mixed with the fuel. This engine pulls from a dedicated 2stroke oil tank. If your motor is a two stroke and requires the oil to be premixed... then you have to include the proper ratio in your mix of gasoline/cleaner. Don't run it without oil!

Really great video it worked. Man i was about to take to the shop..Thank You so Much!!!
Watched all of 2min just to see what the carburetor looked like on an outboard. I know cars and trucks never messed with an out board after about an hour of cleaning and starting it over n over to burn the gunk out she now fires up every time. Just takes a little know-how and effort and a person can accomplish about anything. My wife is happy as a clam now. Now it's time for a beer and a bowl and some TV cause it's been a day. Thanks again.
Good info man. Im off to clean my carbs!
2 things I always do.
1) start the boat at home before leaving to make sure it's gonna run.
2) run the gas out of the carbs so there is nothing to gunk up.
I just got my first outboard, 01' 30hp merc 3cylinder 4stroke. I've been going through it, water pump housing/impeller, fuel filter, oil/oil filter, gear oil, spark plugs, etc. Need to clean the carbs but I've never messed with carbs. Looking forward when I winterize it each year, how do I go about running gas out of the carbs to maintain them, what's that procedure like
Perfect advice. I’ve been doing that for years and my motor always starts right up.
@MrFishaddict707 To be honest... I only do it when I notice a problem. Usually when I haven't run the engine in a few weeks. I figure the fuel must be evaporating leaving the two stroke oil and varnish behind which clogs some of the carb's internals. So I run a concentrated mix until it starts running smooth again. It couldn't hurt adding it to the fuel as per label, but I think there's enough alcohol in modern gas to keep the varnish at bay... if you run the motor often!
Thank you sooooo much! I will try this on my 115 HP Johnson 1995 fast strike V4: I hope it works! :)
96 Yamaha 70 horse outboard motor it will start and run but when you give it start to give it gas it dies have you put your choke on just a little bit and not run when any help would be greatly appreciated thank you
+Steve Mosley I am having this exact issue on a newer motor. From what little I've read, it's a dirty carb, we need to clean our shit lol! If you find anything else man, let me know please, and vice versa! Cheers!
Okay I just got through taking them carburetors apart and clean them up there was a little trash in them but not much I just done it but not put them back together and put them back on the motor it started right up didn't seem like it was running rough but sitting in the yard it run like hell yesterday I'm watching got pressure on him from the water and wouldn't take the gas so I'm going to take it back to the the lake tomorrow I might have to get them carburetors synchronized
But I also read that those are good I know it's got on there on the inside of the cabin but the side of my own
I don't know what's wrong with this damn telephone and just write anything down I said I had to reset the air Jets on the inside of the cowling it has for you set them how many times to go back on them
Hopefully that's the only issue cause i'm itchin' to get on Lake Erie early tomorrow and I've not light here to work on it :( Good luck and thanks for the comments!
great thanks !!!! it fixed my carb problem
I have used every kind of cleaner there is on the market, sea foam is more expensive and it performs, its amazing, sometimes Iput an ounce in my riding lawn and it smooth's right out,, its more expensive but it works guaranteed !
Hi Daniel, my Alex. I tried your method but engine still cut off after a minute or two or when I rev. Up the engine. I did left my boat in storage for a couple of years. Any good suggestion will help. Thanks in advance.
Great video. Can't wait to get at my 150 Johnson. See you also have a crack in the cowl. It's a weak point and they crack from people using the slots as a lifting point. It would be a good idea to screw a stainless handle on to the cowl.
Good to see you back on the water..its been almost/over a 100* the past week. been staying in side..try to take grand son out on the water but he sooner look for rocks with his brothers..need to brain wash him some how.At least I can cool off watching your videos
I have a late 70's mercury outboard, 150 hp,i have to prime the carbs to start it but when it starts it runs good an restarts with the flick of the key. why do i have to prime it, how is it loosing the gas
I had a feeling you were a fellow Louisianian. I live in Dallas now but grew up in Slidell. I just bought a used 16ft Glastron Tri-Hull with a 1978 Evinrude 115hp. Engine works ok but it does need some carb work. No sign of water in oil so I am thinking I can get it running soon with help from You Tube videos. Thanks.
By the way the small ports ur sprayed into are your idle jets. On the ocean pro usually always get dirty good post
Did you get my message on the 2008 Tracker 175 with a 50 hp.
Will that clean the jets on the carbs? Will this method clean the entire carb and all of its parts?
If your going to store an outboard for any length of time you should run fuel stabilizer in the fuel and then let it run through the engine.
I own a 1976 75HP Evenrude, has not been started for 2 years. Checked out your video. Took the cowl off, then the cover with 6 bolts to the carbs. Used half a can inside and outside. Let it sit for 10 minutes. Brand new battery I hooked up. Voila! Runs like a Swiss Watch again. Thanks for the tip, I appreciate it.
if that was chemtool that was too much, chemtool will destroy carb seals quik
THX for doing this video, very helpfuly ....
Where u find that 3 way valley at im looking for one
Awesome Video! Are the + and - on top of the flywheel for the Idle and top end RPMs? Thanks
you mixed that 1 gal 50/1 right? or will it still mix on its on
I have the same motor with the same problem thanks for video 🙏
I've found using ONLY ethanol-free fuel has helped my motor run and start more consistently. I still need to clean my carbs -
looks like the cameraman from cloverfield doing a how to vid........
great video , can you just unhook the fuel line and put it in the carb cleaner solution?
That was a 2001 150hp. It was produced specially as a replacement for the failed FICHT motors that led to Johnson demise. As I have sold the boat I cannot give you the exact model number anymore.
how often do you "clean" the carb? do you recomend putting that stuff in every tank?
good vid, chem-tool rocks,berryman .
Hey Cuz, you need to clean dat boat boy ! If you aint keeping it clean after you use it cher' it's gonna always give ya trouble ! You know dat you gotta get serious about da boat unless you want to spend a lot of time and money on da ting...as I see you already are. Now using that much cleena...you are messin up all your hoses and gaskets bro ! Come on man ! I know you know betta den dat !
where did you learn english
Quick question - how long do Carburetor's typically last before a rebuild is needed on a 9.9HP Johnson motor ? ( hours or years works ) thanks in advance
+pmdtrax187 That's hard to say, a shop would say more often that me. My engine is a 1999, and the carbs, all six throats, are still working super! I use the boat quite often and they are the metal bowl version. I would anticipate the plastic carbs would need more attention. Most rebuilds only address blockage problems and seals.
I totally agree... and do as I say not as I do!
Way too much movement with the camera. Almost unwatchable.
I forgot about yours having oil injection! I have the old 50 to 1 mix and mess system. I also have carb problems. Thanks!
please tell me how did u mix the gas and carb cleaner
im a outboard tec still love that high rev sound a
Hi there , my 90hp Johnson got a problem when it go to high speed , the motor cut off with a banging sound coming from inside the engine ... hope you could help me fix this problem , thanks in advance.
+Tonga Lomu You would have to trouble shoot it or bring it to a professional. Many of these engines have a cutout routine built in at high speeds if the engine starts to overheat.
Wise pre-show disclaimer! Great hair!
have the same engine same prob you nailed it thanx
Hi, I noticed that the motor have smoke when you turned on the engine, I have the same boat with same motor but mine have smoke all the time, do you have any idea of what is the cause?
If your Johnson outboard is smoking all the time, it could have something to do with the oil, I have a 2000 sea swirl striper with an 150 Johnson and mine smoked a whole lot and kept stalling out, brought it to my mechanic and it happened to be the valve in the oil pump was broken and when I filled the oil reservoir the check valve wasn’t working so the oil went directly into the carburetors filling them up, thus causing a lot of smoke and making the motor stall out. This is a common problem with these boats
I just started my Johnson engine today with starter fluid, but it won't stay running. may I know what you add into the fuel? my engine had been sitting for more than a year, tks.
+Loc Lam Becareful to use starter fluid with oil, so as not to damage the motor. There are several products for cleaning carburetors like seafoam, I prefer Berrymans Chemtool. If you get is running right, I suggest a monthly reminder to run the engine... just set it up for the first Saturday in your smartphone. good luck!
what carb cleaner did you use
can you shown me how i can do carburetor my outboard mercury 225 yr 2002 please,
That year is probably fuel injected.
Hi. whats the exact model of this motor and build year? thanks
WHAT DO YOU USE TO CAP YOUR AUXILIARY HOSE?
Good job thanks for. Showing
Place comments and questions here!
Dude,.. Lovin' the background music!!
Where did you get cut off valve and how did you install it?
you shouldn't rev it quite that hard....less than 3000 rpm.
yes im very aware ,, thanks again for the video ,, you da man! safe boating my friend.
How much 2 stroke oil am I using for a 50.1 ratio for one gallon?
2.6 oz per gallon of fuel
Thank you for this vidja
Got it at West Marine for under $40. It's actually a selector valve, but can shut off the fuel also.
thanks for the info ,, good video,, same procedure on a 2 stroke Johnson im assuming?
tudo cervera This is a 2 stroke engine... but the oil is automatically added separately by the engine's VRO pump. If you are premixing in the tank... make sure you use oil in your cleaning mix or serious damage will occur.
has anyone had trouble with a 65 hp suzuki outboard dieing under a load?
+Monte Kubo Make sure it's not overheating.
Best video I have seen on carbs
I agree.
what is it that you mixed with the fuel? seafoam?
thanks man!!!...great info!!!...you rock!!!!!
The only carb cleaner I can find is the spray. What brand is sold as a liquid? Thanks!!
Little late lmao, but you want Seafoam
good vid man. what part louisiana you in?
Hey mr , r u running your boat motor with just carb cleaner
The motor mixes oil into the fuel automatically from a separate oil tank. Many people disconnect this and mix in the fuel tank. I like my engines to run as they were designed, so I do not bypass the oil mix system. Running two stoke motors without oil in the mix will destroy the engine.
Thanks, near Hammond, La.
Hi there I got a evidence 78 115 hp it's wasn't started for 3 year's and when I started it just a click noise from the engine no turnover so I need help please what I should do to make this work again
Did you figure this problem out ?
+Lia Lupeomanu I would start by checking the battery and starter motor.
must be your starter solenoid
Good information ! Thanks!
That's my favorite part! LOL
Thanks.
Good video!
Un
You havent fire up the engine and the water still running for no reason...you waste the most important thing in life..shame on you..
chalakias Most ignorant comment of the day?
Are you a fucking idiot that's the stupidest car at I've ever seen in my fucking life are you a moron
I'm sorry I have to make another comment that's the most stupidest comment I've ever seen in my fucking life I can't believe you had the audacity to put that on the internet because they had the motor water running through the motor without it running what about with your truck turned off in the shower too long you keeping the water running share wife or girlfriend and mama don't see it oh my God I'm going to blow my brains out tonight I can't take this no more
