D SERIES PROPELLER NUCLEUS SOLRBX-125

Function and technical context

The Solas RBX-125 D Series propeller hub is the central component that transmits torque from the propulsion shaft to the propeller blades, acting as a shock absorption element in the boat's propulsion system. Manufactured by Solas for type D propellers, this core incorporates an elastomeric insert that protects the gearbox and drive shaft from sudden impacts, such as impact against submerged objects or rocky bottoms. Its correct operation is essential to ensure efficient propulsion and, above all, to safeguard the mechanical components of the drive train against costly damage.

When to replace this part?

The most common symptoms of propeller core wear include abnormal vibrations during navigation, loss of response during acceleration, slipping between the shaft and blades or metallic noises when power is applied. It is recommended that the hub be inspected at each seasonal maintenance and replaced whenever a severe impact with a submerged object has occurred, even if the propeller shows no visible damage externally. Replacing the core preventively is a low-cost measure that prevents serious damage to the transmission and gearbox, especially in navigation areas with irregular bottoms.
