Drain the carb, drain the fuel tank, fill with fresh fuel/oil. Start the
engine, run the engine for at least and hour maybe two. Then spary
everything with wd 40 again. Including the cylinders. drain the carb,
wait for spring.

I've just recovered my 20 horse Merc outboard from the river. It went under
when heavy rain submerged the small boat it was attached to.
I brought it indoors, dried up what I could, put a heat gun on wet areas,
especially the electrical components, took out the plugs, poured oil in the
cylinders and pulled the starter a few times, drained the lower unit then
sprayed everything I could with WD 40.
a)Have I forgotten anything?
b)What are the odds on getting it going next spring?

Thanks
