I have a 1988 Malibu Skier with inboard 5.7 mercruiser and 1:1 Velvet drive transmission. My boat runs at 3800 rpm WOT with three adults in it. I belive the spec is 4400 to 4800 rpm. It has a 13 X 13 3 blade Mac Master Stainless prop on it now. Some cavitation noted when getting to speed.<br /><br />Question 2. Where does the engine get air from when cover is over motor? Seems pretty restrictive?
