2 Sets of Lower Unit Gear Lube Pump for Standard Quart Bottles Fits All Mercury and Mariner Outboards

Works well

Good price

All ok

Sometimes let air into the liquid but works good for gear lube.

It gets the job done but the hose kept coming off the hand pump. Just an oily mess. It's cheap and a one-time use item. Won't buy again and would suggest shopping for a better one if changing the gear oil is part of your yearly mainternance.

Great

leaked badly at hose/pump connection - also supplied fitting did not for my mercury

It worked, but I couldnt get it to thread properly. I have a supported engine too.
