MULTI-D PROPELLER ALUM.AMITA3 13.80X13 RIGHT

Function and technical context

The Multi-d ALUM.AMITA3 13.80×13 propeller is the direct propulsion element for Yamaha, Tohatsu and compatible brands outboard motors, transforming the engine's power into water thrust by rotating its blades to the right. Installed on the transmission shaft, it works in the marine propulsion system, subjected to hydraulic pressures and constant friction with salt water and sediments. Its correct condition is essential to maintain the running efficiency, the maneuverability of the boat and avoid abnormal vibrations that can damage engine bearings and seals.

When to replace this part?

The most common symptoms of propeller wear include progressive loss of power during acceleration, noticeable vibrations at medium-high speeds, audible cavitation (bubbling sound), and visible deformation or bumps on the blades after impacts with submerged objects. It is recommended that the propeller be inspected at each seasonal maintenance and replaced if it presents structural damage, significant erosion on the leading edges or imbalance; A preventive replacement before the intensive sailing season prevents unexpected breakdowns on the water and keeps the engine performance in optimal condition.
