4 Blades Stainless Steel Outboard Propeller, Marine Boat Engine Propellers 13X19 RH Pitch Fit For Yamaha 50-130Hp Engine, 15 Spline Tooth, Outboard Motor Propeller Boat Propellers

The 13×19 Right-Hand (RH) 4-blade stainless steel propeller is a high-performance upgrade designed for Yamaha outboard motors ranging from 50 to 130 horsepower. In marine propulsion, the propeller acts as a screw-type airfoil that converts the rotational energy of the engine into thrust, effectively moving the vessel through the water. The selection of a 4-blade configuration over a traditional 3-blade design offers significant advantages in terms of grip, acceleration, and stability, particularly in rough water conditions where the propeller may occasionally breach the surface.
