MULTI-C ALUM PROPELLER 11.10X13 RIGHTS

Function and technical context

The 11.10×13 aluminum Multi-c propeller is the fundamental propulsion element of the transmission system of Yamaha and Honda outboard motors. This propeller transforms the rotary power of the engine into thrust by displacing the water, determining the acceleration, maximum speed and consumption efficiency of the boat. The bore and pitch—11.10-inch bore and 13-inch pitch—are calibrated to optimize performance in cruising and recreational applications. Its aluminum construction provides structural strength while maintaining a manageable weight, being especially important in medium-sized boats where the balance between power and buoyancy is critical. A damaged propeller compromises efficient power transmission, directly affecting the maneuverability and fuel consumption of the vessel.

When to replace this part?

A damaged propeller is manifested by abnormal vibrations in the engine, loss of acceleration even if the accelerator responds correctly, or a distinct metallic noise during navigation. It is recommended to inspect the propeller at the beginning of each sailing season and after any impact with submerged objects, replacing it preventively if it presents deformations, cracks or edge erosion. Replacing a damaged propeller prevents secondary damage to the crankshaft and gearbox, intervening before the problem worsens during navigation.
