Fogging a outboard

[samcats]

I have a 02 200hp merc saltwater efi do you fog these engines or just pull the plugs and fog the cylinder. To winterize

Just hit the plugs not to much pull the kill switch and turn over a couple times. Shooting some in airbox while running won't hurt anything.  Do lower unit oil change and keep trimmed all the way down.

I have always treated fuel with stabil first. Then run the engine until the stabil is being introduced into the motor. This of course before fogging the cylinders. I used the red color stabil up until the last two years now I use the blue color (marine). The marine grade treats fuel for 12 months where as the red last up to 24.

I've been using sea foam marine pro motor runs good they say 24 months on gas. But I only use nonlethal gas

I always used stabil marine without any issues but this summer had a mechanic tell me to only use k100 for overwintering, said it was the best.

What is " k100 " ?

Too set in my ways to change now:  since 1954 I have babied my outboard my cylinders for the winter this way, starting then with my 1.1 and last week for my 1986 Yamaha 40EL. I have this antique little trigger operated half pint oil can filled with whatever clean 2-cycle oil left over. with the plugs out and the engine tilted up, I squirt too shots toward the upper cylinder wall and let it sit a couple of minutes then lower the engine and turn it over at least one cycle. I replace the plugs and will change them out in the Spring. I have never had engine issues in the head doing this so I think I may get away with not making the change. I know, TMI, Dave

The question was " fogging " the engine ! ie. spraying fogging oil into the cylinders while the engine is running .

I've always found the owners manual for your particular motor has the information you need.

[tuffishooker]

Ditto on reading the " Owners Manual " first !

Mercury, Mercruiser, and Yamaha both recommend fogging the engine with what we call a "cocktail." Here at Krenzer marine we use a 6 gallon shop tank shop tank filled with 5 gallons of 90 No Ethanol fuel, 2 quarts of 2-cycle TC-W3 oil, and 1oz of Stabilizer. We run the engine on t his for 5-10 minutes. This cocktail lubricates the cylinders and fuel pump.

I've heard about a mixture they use. Now is the quick silver 2 stroke oil ok. And my motor is 2 stroke. That is what I don't understand the internals would be coated I asume and in them motors where does the mixing process takes place

Sound like the mixture is in the tank and the motor runs directly off that gas tank.

Well I talked to mercury and according to them you fog the cylinder only for that model. And I would like to thank all who gave there advice it is greatly appreciated
