MULTI-D PROPELLER ALUM.AMITA3 13.80X13 RIGHT

Function and technical context

The AMITA3 13.80X13 aluminum propeller belongs to the Multi-D series and is designed to efficiently transmit the engine's power to the mass of water, generating the thrust necessary for navigation. With a diameter of 13.80 inches and a pitch of 13, this three-blade, right-hand rotation propeller is designed for mid-range outboard and inboard use, optimizing the engine's operating speed and navigation performance. A propeller in poor condition directly compromises propulsion efficiency: it increases fuel consumption, generates vibrations and can cause engine overheating due to excess or lack of load.

When to replace this part?

The most obvious signs that an aluminum propeller needs replacement are: visible deformations or dents in the blades after an impact, abnormal vibrations during navigation and notable loss of top speed or acceleration. Aluminum, although lighter and cheaper, is more susceptible to impact damage than other alloys, so it is recommended to visually inspect the propeller at each seasonal maintenance. Replacing a damaged propeller preventively prevents secondary damage to the shaft, seals and tail gear, which is considerably more expensive to repair.
