You should talk to the boat builder (as they should know the boats designed performance) - the propeller specialist can specify a suitable propeller (based upon engine horse power and rpm) - we then supply the required engine. (The recommended propellers detailed below are based upon 3 fixed blades and a 2:1 reduction gearbox).
