Cleanoil is essential in reducing friction and preventing damage to internal components, providing many years of engine life. Engineered for sterndrive and outboard lower units, this High Performance SAE 90 gear lube has been extensively tested to ensure impressive protection against corrosion and wear. Specifically formulated to help prevent failures due to water entering the gear housing.

Mercury High performance Gear Lube is for us in all outboard lower units, jet pumps, Sport Jets and all Mercury Mercruiser Sterndrive legs. It provides the proper corrosion protection and lubrication needs of marine gear cases not found in automotive based oil. This gear lube provides maximum protection against water intrusion and excessive wear.

Established in 1946, Hunts Marine is a third-generation family-owned marine retailer with over 75 years experience in recreational boating. We have three great showrooms in Sydney, Wollongong and Batemans Bay which all stock a wide range of fully rigged, clearly priced boat packages.

It appears that my gear lube reservoir is leaking. I have gear lube on the side of engine and in the bilge. I put a real metal clamp on the hose and I'm still getting quite a bit of oil leaking out. The reservoir will drain after about an hour of running. Anyone else had this problem? Any thoughts on what else it could be? Thanks for you help.

your "on the side of the engine" comment is thought provoking... is it leaking from the hose? have you seen it leak/drip or do you just notice the level go down? It could be that the resevoir is cracked. which happens often..

one time when I took my reservoirs off to clean I remember having the barb assembly on the bottom come loose, but couldn't get it tight without reaching into the bottle with needle nose or something and holding the float assembly in place, then I was able to get the bottom tight.

basically the lube bottle connects to the hose and then runs to another connector at the transom. I don't think there are any connectors in between. I would try to wipe down all the oil and locate the leak. Good Luck.
