Review on 🛥️ Slippery Pete Lower Unit Gear Oil Pump for Standard Quart Bottles with Metal Swivel - Ideal for Most Marine Boat Outboard Motors (NOT COMPATIBLE WITH VOLVO PENTA) by Joe Griffin

with some corrections it might be good i used it on my 20hp mercury and the adapter fits fine. The hose tends to fall off the spout when you inflate it or twist it while screwing the hose onto the motor so it can get pretty messy, I recommend putting some cardboard on top. This worked well to pump the oil into the bottom block, not too hard to pump as I only poured a small amount into the bottom block, but you have a hose full of oil that needs to be disconnected and then difficult to store , so i poured the whole thing in a small bucket with a pump and hose. You may want to cut the tubing slightly where it goes over the spout, maybe 3/8 inch, and then put it back over the spout for a tighter fit as it will expand with storage and shipping.
