Mercury Marine New OEM High Performance Gear Lube with Hand Pump, 91-8M0101435

This was easy to use and screwed in securely and the pump worked well; filled the chamber with oil. Would buy again.

came with pump, am so happy with it

You have to hold the plastic hose on the pump or it pops off. This can be easily fixed, but you should not have to do this.

Pump isn’t long enough to get all the oil out. Had to pour the rest into a red solo cup( filled it up to about the 3/4 mark) and put the pump in the solo cup. Slight inconvenience but what ever

Just what the title says.

Best part is the threaded tube end so you don’t have to hold it while pumping the lube.

Great value

The pump has the wrong thread size and pitch for my 25 HP 2008 Mercury Outboard lower end. This is not the fault of the seller. However it would be better if the connector was better described. Some pumps come with adapters to fit virtually any outboard. I made my own adapter from some smaller tubing I had laying around. Not optimum. Also the clear tube is prone to fall off of the pump end.
