🔌 Function

This fitting forms the through-transom/bulkhead connection for the remote gear lube reservoir hose. It allows gear lube to pass between the remote bottle and the sterndrive while maintaining a sealed connection through the gimbal housing area. Correct fitment helps prevent gear lube leaks and helps maintain proper drive lubrication monitoring.

Common signs of failure:

• Gear lube leaking around the transom or gimbal housing fitting

• Cracked or broken plastic fitting

• Oil reservoir level dropping without obvious external drive leak

• Hose connection not locking securely

• Gear lube residue in the bilge or transom area

• Damaged O-rings or sealing surface during hose replacement

📦 Condition

• Genuine Quicksilver part

• Brand new

• Supplied in original or equivalent packaging
