i and my wife. have a 37 ft pacific seacraft. i install a campbell sailer 3 blade on our boat. it has the right pitch and are very happy with it. we have to deal with current here. also. at 2200rpm we can motor a 5knots or better. stops the boat also. i think the dealer is in canada. is it better to have a fixed prop. i dont know, that is all i would use for the price.
