This product is engineered to restore transmission efficiency, translating directly into precise boat response to helm movements.

Installation and Maintenance

Replacing components in the shift shaft housing restores smooth steering operation. Before starting work, we recommend thoroughly cleaning all mounting surfaces from deposits and old sealant. Carefully installing the new seals and rings from the SIERRA kit prevents oil leaks and water ingress into the mechanism interior, which is the main cause of corrosion. Regular replacement of this kit during service inspections extends the lifespan of the entire transmission and protects against costly failures during your cruise.
