ALUMINUM PROPELLER AMITA4 14.5X17 RIGHT

Function and technical context

The propeller is the final propulsion element of the transmission system of an outboard engine: it transforms the mechanical power of the engine into hydraulic thrust on the water. This AMITA4 four-blade aluminum propeller, with 17 pitch and 14.5-inch diameter and right-hand rotation, is sized to work in the optimal engine speed range, guaranteeing efficient acceleration and a top speed appropriate to the hull. A worn, bent or incorrectly pitched propeller causes an increase in revolutions without real thrust, increased consumption and overloading of the motor-gearbox group, which accelerates the wear of internal components.

When to replace this part?

The most common symptoms that indicate that the propeller must be checked or replaced are: abnormal vibrations in the shaft or hull at any speed, loss of top speed or thrust at start-up, and unjustified increase in fuel consumption. A blow from a bass, tangled line, or suspended sand can bend or erode the blades, altering the dynamic balance even when the visual damage appears minor. It is recommended to visually inspect the propeller at each seasonal beaching and replace it if there is any blade deformation, edge erosion or looseness in the hub; Acting preventively avoids damage to the shaft and reducer seals that would increase the cost of the repair.
