What This O-Ring is Used For

This Yamaha O-ring seals the manual release screw area of compatible power trim and tilt hydraulic assemblies.

The manual release screw allows the engine to be manually tilted when hydraulic trim operation is unavailable or when service access is needed.

A worn or damaged O-ring can allow hydraulic fluid seepage around the manual release screw and may affect trim and tilt performance.

Replacing the O-ring during manual release screw service helps maintain proper hydraulic sealing and reliable trim system operation.
