ALUMINUM PROPELLER 9.30X9 RIGHT

Function and technical context

The propeller is the fundamental propulsion element that transforms the engine's power into direct thrust on the water. This 9.30 x 9-inch aluminum propeller works directly coupled to the engine's transmission shaft, taking advantage of the rotation to generate traction by displacing water. Right-hand rotation (clockwise rotation when looking from the stern) ensures correct interaction with the engine's lubrication and cooling systems, as well as predictable maneuverability on boats equipped with medium-power outboard motors. A worn or damaged propeller causes loss of performance, increased fuel consumption, abnormal vibrations and a significant reduction in maximum speed.

When to replace this part?

Inspect the propeller regularly for dents, cracks, deformation of the blades, or corrosion due to insufficient galvanization; These defects reduce hydrodynamic efficiency and generate vibrations that damage the shaft and bearings. It is recommended to check the propeller after each intensive boating season or at least once a year, especially if the boat operates in shallow water or frequently in areas with vegetation or debris. Preventively replacing a worn propeller avoids costly breakdowns in the transmission system and guarantees safe maneuverability and optimal fuel consumption.
