[QUOTE=jamesbalog;228171]my 200hp merc will turn 48-4900 rpms with a 19pitch prop the fastest i have seen on the gps is 43. With my normal load of people and gear i get 38-39.
mines also a 81 so its not making 200 at the prop, boat also has bottom paint[/QUOTE
Yours likely too much prop...........you need 5,500 rpm and will likely get 45-48 mph while the motor will work less hard too.
