YAMAHA CLAMP 90464-07M05

Function and technical context

This clamp is a structural fixing component in Yamaha outboard motors, responsible for securing and maintaining the ducts, hoses or elements of the engine's internal systems in the correct position. It works within the overall mechanical architecture of the propeller, supporting operational vibrations and ensuring that cooling, fuel or lubrication passages remain firmly attached without displacement during navigation. Its correct function is critical to prevent fluid leaks, avoid friction that damages hoses and ensure that the engine systems operate without interference or abnormal movements that compromise the sealing or integrity of the pipes.

When to replace this part?

Check the condition of the clamps at each seasonal maintenance, especially if you notice fluid leaks in areas where there should be pipes or hoses clamped, abnormal engine vibrations, or if you detect that the hoses have changed position with respect to their normal location. Accumulated wear from vibration fatigue, exposure to salt moisture, and temperature changes can cause these fasteners to lose tension or fracture. Preventively replacing worn clamps prevents unforeseen navigation breakdowns and protects the integrity of critical engine systems.
