I am curious how to determine what prop size would be ideal for my boat*
I have a 17ft RIB with E-tec 40 and now I have 13.5x15 prop on it, looks huge prop that's for sure, and I bought it like that
cruise speed is around 20mph and max around 28-29mph
anyone knows is this good combo or should I go for smaller prop?
allround performance and low consumption is my goal
