Hello all,

It's been a while since a posted. I have my boat all tucked away for the winter and really didn't have any problems winterizing it. I just got done putting all new wires in it (thanks mouse:mad:) and had a question about decarbonizing the motor. Here are the specs:

1992 Johnson 60 hp VJ60TLENE
no idea about the hours on it
I run TWC-3 oil in it (pennsoil)
Never been decarbonized to the best of my knowledge

My first question is decarbonizing it. I know the cans of stuff are pretty idiot proof, but having never been done is there anything special I should do? Also what kinds off additives do you recommend running in it i.e. Seafoam ect.

My second question, is the oil I've been using ok or should I use something else.

Thanks for all your help!!!

Re: decarbonizing

this is the method it use.

Decarb, take a can of seafoam put 3/4 of it in the gas tank, with only 1 gallon of premixed gas. put the rest in a spray bottle. start the engine, and let it come up to temperature. then remove plugs, and them some real good shot of seafoam into the cylinders, replace plugs, let sit 15 minutes. restart, and spray the rest of the seafoam into the carbs, so the the motor almost stalls, wait and repeat until the seafoam is gone.then take for a wide open spin. then put in new plugs, ad premixed gas to the tank, and take it for a wide open throttle spin. it is going to smoke like a house on fire, during this process.

afterwards, run seafoam in you fuel/oil per directions.
