MULTI-C ALUMINUM PROPELLER 12.10X9 RIGHT

Function and technical context

The propeller is the fundamental propulsion element that transforms the power of the engine into movement of the boat. This 12.10×9 pitch aluminum propeller with right-hand rotation works in the propulsion system, responsible for moving the water backward to generate the thrust that moves the bow forward. Its design and material are critical to overall performance: a worn, damaged or poorly balanced propeller causes excessive vibration, loss of speed, increased fuel consumption and overloading of the tailshaft bearings. Aluminum, although lighter than other alloys, offers an excellent balance between durability and ease of repair in the event of accidental impact.

When to replace this part?

It is advisable to check the condition of the propeller at the beginning of each season and after any contact with rocks, logs or shallow bottoms. The most common symptoms of wear include abnormal vibrations in the spreader or transom, reduction in maximum revolutions at full power, or visible misalignment of the leading edge. Although aluminum resists continued use in salt water well, the galvanization can degrade over time, so replacing it preventively avoids running out of propulsion during a journey and ensures safe and efficient driving.
