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

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.

Took 4-5 full pumps to fill my 77, 4.5 h.p. Merc.

As described

The oil is fine, the pump doesnt reach all of the oil no matter which postion you hold the bottle of oil in. Really dumb, a quart of oil which at best you can pump 2/3 of a quart out of it.

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

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

Great value

Does not thread into lower unit for 8ph mercury 4 stroke. I took a chance and will have to order a different insert. Oil is correct for my model

Worked great.

Price was great and came with a pump. Delivered on time!
