TRANSMISSION SHAFT 689-45501-10 REC689-45501-10

Function and technical context

The 689-45501-10 drive shaft is the critical component that transfers the power generated by the engine to the propeller, allowing the boat to move forward. This axle works integrated into the propulsion system, supporting continuous mechanical stress and high-revolution rotations. Its correct operation is critical to maintaining efficient and safe propulsion, since any deterioration or misalignment can cause abnormal vibrations, loss of traction and damage to the support bearings.

When to replace this part?

The most common symptoms of wear on the drive shaft include noticeable vibrations during navigation, metallic noises from the propulsion area and gradual loss of thrust power. It is recommended to inspect the shaft at each seasonal inspection, especially in boats that are used intensively or that navigate in waters with sediment. Preventive shaft replacement prevents catastrophic breakages at sea that could result in high-cost repairs and compromise navigational safety.
