Drained my lower unit and then attached this to the top of the yamalube gear. Connected the adapter piece to the end that fits my drain screw thread pitch and began pumping. Pumped very easily and with sufficient flow. Did not introduce much bubbling or foam so didn't have to wait too much to fill a bit more after coming out of the vent hole. Highly recommend. Simple product for a reasonable price.When i was done i put the end of the fill tube into the mostly full second quart and then slid it off the pump to allow the oil in the tube to drain into the quart. Then just put it all back in the bag with the rest of the sealing washers I had to have it ready for the next oil change. ### ⭐⭐⭐⭐⭐ worked perfectly *by on Reviewed in the United States 10 July 2024* I used this pump to replace the lower unit oil in my Honda 20 HP dingy motor. I use OEM Honda Lower Unit oil which has a wide mouth top. this pump fit perfectly and included the correct screw in adapter to fill the lower unit case. seems well made, no leaks and pumps fine. I would recommend it if you're looking for a decent little hand pump. ### ⭐⭐⭐⭐⭐ Prompt delivery *by on Reviewed in Australia 29 January 2026* Awesome product ## Frequently Bought Together - Slippery Pete - Lower Unit Gear Oil Pump for Standard Quart Bottles, Includes 3/8 inch Metal Swivel, 8mm and 10mm Adapters Fit Most Marine Boat Outboard Motors (NOT COMPATIBLE WITH VOLVO PENTA) - Quicksilver 858064Q01 High Performance SAE 90 Gear Lube for Mercury Outboards and MerCruiser Sterndrives, 32 oz - Quicksilver 802859Q1 2-4-C Marine Grease with Teflon, Multi-Purpose Marine Lubricant – 8 oz.
