ALUMINUM PROPELLER AMITA4 14X21 RIGHT

Function and technical context

The propeller is the propulsion element that transforms the mechanical power of the outboard engine into effective thrust on the water, being decisive for the performance, consumption and response of the boat. This AMITA4 aluminum propeller, with 14×21 pitch and right-hand rotation, is designed specifically for Suzuki engines, guaranteeing correct adaptation to the hub and transmission system of the propulsion group. The diameter and pitch are optimized so that the motor operates within its recommended rpm range, maximizing propulsion efficiency and protecting the impeller from overload. An inadequate or damaged propeller can cause a notable loss of top speed, increased fuel consumption, shaft vibrations and progressive damage to the transmission system.

When to replace this part?

The most common symptoms that indicate the need to change the propeller are the appearance of abnormal vibrations in cruising speed, loss of speed without apparent cause in the engine, excessive cavitation or warping and visible deformations in the blades after an impact with a submerged object. It is recommended to inspect the propeller at the beginning of each season and after any impact, as even slight damage to the leading edge of the blades significantly affects performance. Replacing it preventively in the event of minimal structural damage avoids unnecessary stress on the axle and gearbox, preventing higher cost breakdowns in navigation.
