My brother has a a 23 foot Caravelle with a 350 Mag and a bravo one drive with a 1.50 drive. Im in New Mexico and the lakes here are any where from 4400 feet to 7000 feet. the boat is brand new and came with that drive from another state. He is only getting about 3700 RPMs at wide open throtle.The dealer he bought it from told him he need ed to change out the gears in the drive other wise it could cause severe damage. Im thinking just changeing the prop he has a 21P 3 blade thought he should try a 19P any advise would be great
Thanks Vince
that would get 200rpm back give or take.
