ALUMINUM PROPELLER 11.5X11 RIGHT

Function and technical context

The right 11.5x11 aluminum propeller is the fundamental propulsion element that transforms the power of the engine into movement of the boat. Its 11-inch pitch and 11.5-inch diameter position it for mid-engine applications, where a balance between acceleration and cruising speed is required. It rotates to the right (when viewed from the stern), an essential characteristic for correct power transmission in right-hand rotation axes. Wear on the blades or deformation drastically reduces propulsion efficiency, increasing fuel consumption and limiting the performance of the boat.

When to replace this part?

Aluminum propellers suffer progressive erosion due to cavitation, impacts against submerged objects and salt corrosion, manifesting in loss of thrust, unusual vibrations during navigation and visible reduction in engine performance. It is recommended to check the condition of the blades before each navigation season and replace them preventively if cracks, deformations or significant erosion are detected on the leading edges. A deteriorated propeller not only reduces performance, but can damage the boat's transmission and shaft, generating high-cost repairs.
