REVERSE PINION 67F-45570-00

Function and technical context

The reverse gear is a fundamental component of the transmission system that allows the rotation of the propeller shaft to be reversed when rearward movement of the boat is required. This bevel gear works in close coordination with the gear shift mechanism, transferring engine power in reverse to the marine gearbox. Its correct operation is essential for docking maneuvers, reversing in port and navigation safety operations, since a failure in this component would completely eliminate the boat's reversing capacity.

When to replace this part?

Wear of the reverse gear sprocket is mainly manifested through abnormal noises (squeaking or creaking when engaging reverse gear), difficulty engaging reverse gear, or complete loss of reverse ability. This component should be inspected during seasonal maintenance and checked especially after intensive navigation or frequent docking maneuvers. Preventively replacing this pinion avoids being left without maneuverability in critical situations and prevents secondary damage to the marine gearbox.
