D SERIES PROPELLER NUCLEUS SOLRBX-108

Function and technical context

The RBX-108 D Series propeller core is the central component of the propulsion system that transmits the power of the marine engine to the water through the rotation of the blades. This element works integrated into the transmission shaft, supporting extreme mechanical stress derived from acceleration, braking and changes in direction of the boat. Its deterioration causes excessive vibration, loss of propulsion efficiency, abnormal noises in the gearbox and, in advanced cases, damage to the motor bearings and water entry through the shaft seal.

When to replace this part?

The need to replace the core is evidenced by pronounced vibration during navigation, rubbing or friction noises in the propeller area, and loss of speed despite maintaining constant engine revolutions. It is recommended to inspect this component every season of intensive navigation or after hitting submerged objects, and replace it preventively if it presents microcracks, deformations or visible erosion, thus avoiding serious breakdowns in deep waters that require high-cost repairs.
