Sheesh, all of the ones I carry have water pumps built in, throw out the lower unit pump it is a pain to repair. I use a separate pump with clear tubing set so you clean it topside. That's what we do, mostly outboards. The motor will probably heat enough to make tubing hard to control, and it leaks. Byee, Cal

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,__._,_.___
