- Remove the Drive Unit: Start by disconnecting the drive unit from the transom. Use the socket wrench to remove the bolts securing the drive to the boat. Carefully pull the drive unit out.
- Access the Bellows: Once the drive is removed, locate the bellows. They are typically situated near the transom assembly.
- Disconnect Old Bellows: Use the screwdriver to loosen any clamps holding the old bellows in place. Carefully detach the bellows from both the drive and the transom.
- Install New Bellows: Apply marine lubricant to the edges of the new bellows for a better fit. Position the bellows over the drive and transom, ensuring they seat properly.
- Secure Bellows: Tighten the clamps around the bellows to ensure they are secure. Double-check that the bellows are seated correctly and are not pinched.
- Reattach the Drive Unit: Align the drive unit back into place and secure it with the bolts. Ensure everything is tightened to the manufacturer’s specifications.
- Test for Leaks: Reconnect the battery and test the system. Check for any leaks around the bellows during operation.
Expected Results After Replacing Bellows
