Gotta question - do your engines have an EMM (Engine Management Module
- aka "computer") and if so, how is it cooled?

Tom,Computers on cars and large diesel equipment arn't cooled via
special aperatus. So I don't see why they would be on a marine
application.

I recall reading that they are. * They are mounted on a heat sink that in
turn is mounted on a surface that the heat is removed from by the engine's
water cooling system. *The outboards don't have the ambient, convective
cooling that cars and trucks have.

There were some early, computer controlled outboards that had some problems
due to inadequate cooling of the computer, although I don't remember which
engine manufacturer it was. *I don't think it was Etec and whoever it was
redesigned it to resolve the problem.

Heat is not a friend of microchips, that's for sure.
