ALUM PROPELLER RUBEX 3-D 13.5X15 RIGHT

Function and technical context

The Rubex 3-D aluminum propeller is the direct propulsion element that transforms the engine power into marine thrust by rotating its three blades. It works in the propulsion system, coupled to the tail shaft and driven by the gearbox, and is essential to achieve the speed, maneuverability and traction capacity of the boat. The three-dimensional design optimizes hydrodynamic efficiency, improving acceleration and reducing the revolutions necessary to reach cruising speed. Damage, deformation or corrosion of the blades drastically reduces the available thrust, increases vibrations in the shaft line and consumes more fuel by forcing the engine to work at higher revolutions to maintain speed.

When to replace this part?

Aluminum propellers require periodic visual inspection looking for cracks, bends, loss of material due to cavitation or erosion on the leading edges, and damage from hitting rocks, reefs or submerged bodies. If you observe excessive vibrations, loss of maximum speed, asymmetrical behavior in turns or abnormal increase in fuel consumption, it is advisable to remove the propeller to inspect its condition. It is advisable to check and clean the propeller at the end of each sailing season and replace it preventively if any structural defect, even minor, is detected, to avoid catastrophic breakages during navigation in adverse conditions.
