Direct Replacement
The 14 1/2" diam. x 21" pitch outboard propeller is compatible with the Volvo Penta SX Drive...All models, directly replacing OEM 3860709. Our boat propeller relies on the blades' rotating in the water to convert the engine's rotational power into propulsion, which will suit your boat well.
Strong Thrust & Stable Propulsion
Our boat propeller can quickly tighten the vortex, providing a powerful thrust for the ship's propulsion. The unique blade design of the propellers allows your boat to accelerate faster and allows you to control movement in the water with greater precision. It is suitable for various water recreation activities - from family fun to sports competitions, bringing more joy to water-skiing.
14 1/2" Diameter x 21" Pitch
The two main measurements of a boat propeller are diameter and pitch. Pitch is the theoretical distance a propeller will move through the water during each revolution, and diameter is the distance across a circle encompassing all the propeller blades. With 14 1/2" diam. x 21" pitch, our outboard boat propeller will ensure your ship moves ahead smoothly and quickly.
Upgraded Rubber Hub
The outboard motor propeller is built with a rubber hub and 19 tooth splines. The wear-proof hub also has a strong damping effect, designed for cushioning and protecting the drive train from most shocks.
Duplex Stainless Steel
Our corrosion-proof outboard speed props are made from duplex stainless steel and built to last. It has been treated with a vacuum solution and features high tensile strength making it resistant to rust, even under seawater and freshwater.
