80680M – Shift Plunger – Mercury

80680M Shift Plunger is a genuine Mercury gearbox shifting component used in many outboard lower units. This plunger helps engage the shift mechanism correctly during gear selection.

The shift plunger sits inside the gearbox shift system and controls movement between forward, neutral, and reverse. Over time, these parts wear or become damaged. Therefore, replacing worn shift components prevents gear slipping or hard shifting.

A faulty plunger can cause poor gear engagement, grinding noises, or the engine jumping out of gear. Because of this, correct shifting parts are critical for safe operation. This Mercury shift plunger restores proper movement inside the gearcase.

This part is in good usable condition and suitable for gearbox repair, rebuild, or service work. It is ideal for workshop repairs or replacement during lower unit overhaul.
