Used boat came with a canvas cover for the engine cowling.
What are the pros and cons (if any) to covering your engine (heat buildup, etc.?)

It strikes me that the cover is for mooring or storage, not running.

Cutting of the motor's air supply would be the big draw back.

I can't think of any reason to run a motor with a cover on it...

I suspect that John isn't interested in running with the cover on and that he is concerned about heat buildup under the cover while the boat is stored.

I have always wondered if the covers cause the powerheads to sweat like crazy in the summer. If they do cause sweating, the covers are doing more harm than good. I think that air circulation would be a good thing and that the covers will severely restrict any such circulation.

The cover for my Montauk has a built in engine cover. I have had no problems with sweating. I very seldom trailer with the cover on but the times I have there is no problem. If it is a good quality engine cover with a good fit there should be no problem trailering with it either.

Cause sweating?? no way. The engine doesn't
have pores. If anything, it would keep
the engine dryer because the inceased temp
would cause a decreased relative humidity.

Here in Maryland, our relative humidity in the summertime typically runs as high as 90%. Yes, the humidity level exceeds the temps at times. When night comes after a high humidity day, this causes condensate to form under just about anything that has been covered.

Sweat....dew.....same thing. It is the sunlight that ruins engine decals & paint. I keep a cheapo grey canvas cover on my Zuki and it does not sweat(in FL) and is water proof. The fit is pretty crappy so air can easily circulate. I have also been using a Sunbrella cover(black) on my 94 Johnson in NJ since 94 and it still looks new(cover and engine). You still have to wax them, etc but the lack of UV's really keeps them nice.
