Proper prop and size

[krfplay]

I have a 34 ft sport cruiser, twin inboards, 11000 pounds. Currently I have twin brass 3 blade 18x15 pitch. Im not looking for speed but performance/economy. Would I be better with a higher pitched prop ?

A higher pitch prop may put more of a load on your motor - in turn less fuel economy. The proper pitch propeller for your boat is one that lets your motor turn the recomended R.P.M.'s. Then you should have maximum preformance/speed/economy.
