Ken, My buddy has a 50" Bonzi "V" hull with an autobailer mounted to the left of the strut, way down low. It's been working good for him too. z00100, do you have a name? LOL YES, The engine is water cooled, and the pipe is too. Look again at the first pic. The water pickup is on the rudder. From there it go'es into the cooling ring on the engine, out to the cooling ring on the header, out to the cooling ring on the pipe, then exits on the left side of the hull thru thems 2 lil silver thingies I made.
