MULTI-D PROPELLER ALUM.AMITA4 13.30X13 RIGHT

Function and technical context

The AMITA4 13.30X13 right-hand turning aluminum multi-d propeller is the fundamental propulsion element that transforms the engine power into hull movement. Installed in the tail of the outboard motor, it works in the propulsion system by converting the rotation of the shaft into direct thrust on the water. Its four-bladed aluminum design guarantees efficient power transmission, while the marine corrosion-resistant material prevents degradation due to exposure to salt water. A failure in the propeller or its progressive wear generates loss of power, overheating of the engine due to an increase in compensation revolutions, and in extreme cases, water entering the engine cavity.

When to replace this part?

The propeller should be inspected regularly for blade deformations, aluminum hub cracking, advanced corrosion, or material loss due to impact. If you detect abnormal vibrations, a reduction in maximum revolutions even when accelerating fully, or the engine tends to heat up more than usual, it is a sign that the propeller requires immediate replacement. It is recommended to check the condition of the propeller at least once per sailing season and, in waters with debris or rocks, carry out visual inspections after each departure; Preventively replacing the worn propeller prevents engine failure at sea and prolongs the life of the shaft bearings.
