hi guys I was wondering if there is ant kind out bolt on upgrades to achieve more power out of an 88 black max 200 or someone around San Diego that knows how to tune them for more power . I have a 21 foot sleek craft and it gets the boat up to 55mph I have tried changing prop sizes and still cant get past 55mph.

More trim! Jack plate or solid mount?

it has a jack plate

Lower the jack and trim her up... Just don't get her wet, we ran an 18' advantage bubble with a 200 black max and got 72
