4 stroke engine fogging question

[Guest]

Hello,

I have finally accepted winter is here and I am not going to get out on the water again (in my boat any way) until next spring. I just purchased a new boat with a honda 4-stroke this spring. The manual is lacking any information on winterization. I can easily drain and change the oils, stabilize gas, drain carbs, store batteries, etc. My question is how to fog the engine?

I have read various views online about fogging 4-stroke engines. Some say spray the cylinders only. Is this right???

Thank you,

Biff

Scince you have a 4 stroke spraying the clyinders is fine.

The benifit of spraying through the carb on a 2 cycle is your fogging agent gets in the the crank.

the manual on my f80 yamaha four stroke says; Put the cuffs on the engine and start it, letting it warm up to operating temperature, then spray fogging oil into the air horn until the engine almost dies, then shut it off and then spray the cylinders, a couple times and bumping the engine while doing so
