Installation Guide

1. Disconnect the battery and ensure the engine is completely off. Secure the boat on a stable surface or lift.

4. Carefully remove the old cone clutch sliding sleeve, taking care not to damage the clutch hub or splines. Clean all mating surfaces thoroughly.
5. Check the new sleeve for any debris or damage. Align the splines and slide it onto the clutch hub until fully seated.
6. Reassemble the clutch assembly and reinstall the lower unit, following torque specifications in your service manual. Refill with the correct gear oil and reconnect the shift linkage.
7. Reconnect the battery and test the shift operation in and out of gear. Verify smooth engagement before launching.
