TOOTHED SELECTOR 6G1-45631-00 REC6G1-45631-00

Function and technical context

The gear selector is a critical mechanical component in the transmission system of Yamaha, Mercury and Mariner outboard motors. This part acts as an intermediary in the gear shifting mechanism, meshing with other components of the gearbox to allow fluid selection between forward, neutral and reverse. Its serrated design guarantees precise coupling and prevents slipping during navigation maneuvers, being critical for the safety and control of the vessel, especially in docking or anchoring situations.

When to replace this part?

Symptoms of wear on the gear selector include difficulty engaging gears, metallic noises in the gearbox when changing gears, or a feeling that the gears are not locked correctly. It is recommended that this part be inspected during each seasonal maintenance check, especially if wear on the teeth or excessive play in the mechanism is noted. Preventatively replacing the gear selector when the first signs of deterioration are detected prevents secondary damage to adjacent gears and costly repairs to the entire transmission.
