My cowling uses the rain-proof factory ventilation port with fan pulling air up thru motor and out that port. After 11 years neither motor nor controller have corrosion...but then my boat is moored 90 miles up the Columbia river...YMMV...

PS -- If you vent the cowling I will guarantee that at some point rain will get into the power head, possibly good bye control module. Not having to service the water pump in the motor is a good reason to go electric.

Subject: [Electric Boats] pmac water cooling?
On my 20' sailboat, since I don't already have a shaft, have decided to do an outboard conversion. With the outboard occasionally subject to splash I,m concerned about venting the motor cover for cooling. The outboard lower end already has a water pump. Would wrapping some copper tubing for cooling around the motor case, maybe held on with epoxy, add enough to the cooling to be worthwhile?
thanks,__._,_.___
