Re: Advice on winterizing vintage outboards

[jerry-ahrens]

I respectfully disagree with NOT fogging motors. I fog all of them for winter, or if I know I’m not planning on using them for awhile. I’m one of those guys that gets motors serviced, up and running, then hangs them up on the rack. Fogging allows them to be stored for along time without worries… At least spray some in the cylinder if nothing else. I run em all dry while fogging at the same time.
The original question had to do with lower units freezing up, I believe. I’ve never really thought about that issue.. there are several -100 and even -200 RV antifreezes available. maybe you could dunk the lower units in this solution? Just a thought.
As a pretty fair test of fogging, I have two identical 12 hp Sea King’s hanging under my deck outside. The old wedge head motors.
Both cranked over well when stored out there and under cover. One had been fogged well and hung there for a a couple years or so,
then I found another one and hung it there also. I never did get around to fogging or oiling up the cylinders… on the last one. After a year or so, I was out there one day and uncovered them. One still cranked over fine. The other one, was stuck tight! I have it soaking,
but haven’t got back to it yet. I should have took the time to do it right..
