AMITA 3 PROPELLER 14X19

Function and technical context

The 14x19-inch Amita 3 propeller is the propulsion element responsible for transforming the power of the outboard engine into effective thrust on the water, working directly on the tail shaft in the engine transmission system. With three blades and a design optimized for medium and high power engines, this propeller is designed to offer balanced performance between acceleration and top speed in boats for sports, recreational and fishing use. A pitch of 19 inches orients it towards applications where cruising speed is prioritized, making it crucial that the engine works within its optimal RPM range to avoid overloading the crankshaft and the conical group. Wear or damage to the blades causes loss of efficiency, cavitation, vibrations in the transom and increased fuel consumption.

When to replace this part?

The most common symptoms that indicate that the propeller needs to be checked or replaced are: unusual vibrations in the stern during navigation, loss of top speed without apparent cause in the engine, increased consumption or inability of the engine to reach maximum idle RPM. Bent, notched, or cavitation-eroded blades dramatically reduce thrust and can transmit damaging stresses to the gearbox. It is recommended to visually inspect the propeller at each seasonal maintenance and after any impact with a submerged object; Replacing it preventively in case of the slightest damage avoids major breakdowns in the conical group and the propeller shaft far from the port.
