Re: Fogging?
Fogging is done by running a heavy amount of oil through the engine to coat the internals, crank, rods and bearings. There are a couple of ways to do this, they make an aersol can that you can squirt directly into the carb. Or you can mix up a small amount of fuel mixture heavy on the oil side. You can also use a squirt oil can with oil in it and squirt it directly into the carb. Remember that you want to get a lot of smoke out of the exhaust
Change your lower unit oil and use new seal washers on the drain/vent screws. Drain the fuel from the carb and spray the power head down with something like WD-40, that's what I do for winter storage.
