ALUM PROPELLER RUBEX 3-D 13.3X17 RIGHT

Function and technical context

The 13.3 x 17-inch Rubex 3-D aluminum propeller is the propulsion element responsible for transforming engine power into direct thrust into the water. It works in the boat's propulsion system, connected to the engine's output shaft, and its rotation generates the movement necessary to move the bow. The three-blade design with aluminum alloy provides an optimal relationship between strength and lightness, allowing the motor to reach its rated revolutions without overloading. Progressive wear of the blades or structural damage to the propeller causes loss of traction, increased fuel consumption and abnormal vibrations in the shaft line.

When to replace this part?

Signs of aging include noticeable vibrations during navigation, reduction in maximum speed without changes in engine speed, metallic noises coming from the stern and material detachment from the blades. It is recommended to inspect the propeller at least once per sailing season, especially after sailing in waters with debris or rocky areas, since small deformations are amplified over time. Preventatively replacing a damaged propeller prevents accelerated thrust bearing wear and costly damage to the drive system.
