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

The threaded end fitting, at the end of the hose, did not fit my drain plug on our 2015 Mercury 25 HP. I had to improvise.

Everything I needed to change my oil in this kit.

Great value

Fits my unit but the hose line will pop off when pressure is up

Bought this for my 2017 mercury 15hp and the threads didn’t match the gear lube drain/fill hole. It’s a plastic fitting and maybe if it were brass, it might of worked. I had to taper the threads with my knife for it to work.

5 Stars

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

Exactly what I needed

Been running this gear lube for years and had 0 issues

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
