Seafoam decarb
I am thinking about spring tune up as we draw closer to spring. Has anyone used seafoam by mixing can to 3/4 gallon of gas with 50:1 two cycle oil mixtures and feeding to engine idling for ten minutes on cups then letting sit for 15 then repeating process. Just looking for results or advice. Will be doing this to 97 Johnson oceanrunner 200 carbed engine.

Re: Seafoam decarb
I used that method on my 96 225hp Johnson except I use a tub instead of the muffs. After the waiting period there was lots of smoke and the water was much darker and more oily than any normal flush I performed before. After the second break and water change there was less smoke and the water was less dark. Overall after the decarb it seemed like it idled smoother and the throttle response was a bit quicker.

Re: Seafoam decarb
Thanks for the reply. I am planning on doing this in spring and can see how using a tub might be beneficial to muffs might help clear out crap being completely submerged.
I plan on doing the 3/4 gallon gas to 16 oz of seafoam, and in addition I do not know what I was thinking probably about last engine on previous boat that was premix fuel, I did not block off the VRO pump and premix on this engine, and hence would not need to mix oil in the fuel. A little might not be a bad idea, but I am unsure anyone want to chime in feel free.

Re: Seafoam decarb
If you have an older 2 stroker, Seafoam is the bomb. Clears all the carbon build up out and "makes your engine run good like it used to could"
The stuff is amazing!! Carbon build up in those older non injected engines is what causes a lot of failures and Seafoam will take care of it.

Re: Seafoam decarb
Mine is a 97 Johnson oceanrunner which is one of the last years for the carbs so I am going to give it a try. Think I am going to do the gas can method mixing 3/4 gallon to on can of seafoam method and then pull plugs and spray some in each cylinder and tilt engine up and hand turn flywheel a few revolutions then replace plugs and let sit. Then fire back up.

Re: Seafoam decarb
Sounds like a good method D Mac.... Most importantly and as you mentioned, let it sit and soak.
When you first restart keep the RPMs low and just enough to idle. It will smoke like on of those old Mosqueto trucks. Once the smoke has subsided you want to take her out and put her under a normal load and this will burn off more. After running around for a while at your normal RPM give her a few bursts at wide open throttle and the rest should burn off.

Re: Seafoam decarb
I use it aswell on my 95' 25hp Johnson. I add alittle in my fuel to keep those carbs running clean.
I also keep some in a spray bottle incase I spray some down the throat. FYI, replace your spark plugs after the decarb!

Re: Seafoam decarb
And make sure the engine is up to temp before u pull the seafomaed treated gas into the engine, then let it sit properly once inside.
Wash rinse repeat You will kill any flying bugs/mosquitos in the area |
