MULTI-D PROPELLER ALUM.AMITA3 13X19 RIGHT

Function and technical context

This AMITA3 aluminum propeller with a diameter of 13 inches and a pitch of 19 is part of the propulsion system of the outboard motor, being the last link in the transmission of power between the engine and the water. Its three-blade, right-hand rotation geometry is designed to optimize performance in medium and high-power Suzuki engines, both the DT (two-stroke) and DF (four-stroke) series. A poor condition of the propeller has a direct impact on propulsion efficiency, fuel consumption and the ability to reach optimal engine operating speed. The combination of diameter and 13×19 pitch determines the load that the motor works, it being essential that the motor-propeller assembly is correctly matched to avoid overloads or cavitation.

When to replace this part?

The most common symptoms that indicate that the propeller needs replacement are: abnormal vibrations in the shaft or transom, loss of top speed or difficulty reaching the manufacturer's recommended RPM, and excessive cavitation visible in the water. Bent, notched, or cavitation-eroded blades significantly reduce performance even when the damage appears minor to the naked eye. It is recommended to inspect the propeller during each seasonal maintenance and replace it preventively in case of any deformation, since sailing with a damaged propeller can end up affecting the shaft, the water seal and the internal components of the gearbox.
