I think the reason for a maxiprop is to reduce sailing drag... Period!!. Pitch and diameter are separate issues. If you have the right pitch and diameter then it is irrelavent whether it's a feathering prop or fixed prop. The feathering prop just reduces tha drag while sailing. It also may have more thrust backing. Most go with a fixed prop because feathering props are expensive. So if it has the right pitch and diameter I'd stay ith what you have. If you don't have enough blade area... cavitating under load then you may need three bledes instead of tow. At this point I recommend Dave Gerr's book "The Propeller Handbook" (in most librarys) which is difinative on all aspects the subject.
