I will have to change the propeller on my Colvic MS31. the engine is a Thornicroft 90 and the prop is that recommended by the designer ie 17" x 10". I have had various recommendations from prop manufacturers. Anybody out here with some experience with this boat. 15" x 12 appears to be a good replacement?
