Review on Efficient Marine Lower Unit Fluid Pump: Performance Tool W54150 by Henry Johnston

pumps fresh gear lube well. Actually - I have Alpha-Gen 2 Outdrive (Mercruser). Separately drain the old grease from the output gear and from the canister located on the motor (simply pull the hose from the canister to the top of the output gear - if you have a 2nd generation. 1st generation: you don't have a canister that does extra lubrication contains - if the output gear is slightly leaking - excess grease will automatically flow into the forward gear). I then started pumping grease into the bottom hole of the output gear, once the grease was visible in the top hole - it started to flow - I reconnected the hose and continued pumping until the grease was visible in the reservoir on the motor was , then you can close the bottom hole and the top container if you have it. Do not close the container lid too tightly. On a cold day, warm the lube in hot water - it should be thinner.
