boat propeller / fixed-pitch / shaft drive / 4-blade
Number of blades:
Designed specifically for medium to fast boats (15-35 knots) or work boats that demand high performance and have restriction on diameter while requiring a higher pitch. Made of high tensile manganese bronze. High-precision static and dynamic balance. High skew blades reduce noticeably noise and vibrations induced in the boat's rudder and hull. To achieve best performance, an ogival-airfoil mixed blade profile has been designed to minimise cavitation whilst providing smooth and effective thrust. Propellers made with antisinging edge. Diameter and pitch in inches.
