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

I have no idea about this product except my husband used it and he seemed okay with it. Came quickly.

Good product

Exactly what I needed

2006 mercury 40 hp.

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.

Perfect

Ease of use

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

What Mercury recommends for my 115 HP. Only complaint is the clear hose will come off of the end that goes in the foot if you try and pump to hard.

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.
