[QUOTE="PSG-1, post: 292766, member: 6937"] Are you going to put cowling scoops over the top of those vent holes in the transom? If it were me, I'd have one facing forward, and one facing rearward, and build them in a manner that water has to be a couple of inches deep before it will enter those scoops. Reason being, if you get out on the water and start doing spins or doughnuts, etc, or if you get in rough conditions, or there's a large boat wake, water can come over the transom, and flood the engine compartment. Having one facing forward will feed fresh air in to the engine compartment, and having the one facing toward the rear will allow some of the heat from the engine to vent out, as the cooler you can run an engine, the better. If you do this, then you don't have to cut any ventilation holes in the front of your cowling. Putting a hole in the front means more noise right behind the operator, something you don't really want. Also, if you line the engine compartment with egg crate foam, it will make a HUGE difference in the sound levels. [/QUOTE]
