Does anyone have one of these boats? If so what engine do you have? What cruising speed are you running? I’ve got a 27’ Nauset. I’m replacing the original 5.0 Mercruiser with a Mercrusier 5.0 MPI. I plan to run the new engine at a higher rpm while cruising to gain more speed. With the original 5.0 I’m cruising 12ish knots at 3000 rpm. WOT the engine turns 4000 rpm with a 17x15 three blade prop.
