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

Great value considering it was 1/2 what a local boat dealer wanted

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.

Perfect

Used for low end on 2007 Mercury 60hp 4 stroke

Ease of use

excellent product, great quality, right for the job

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.

2006 mercury 40 hp.

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

Worked perfectly!
