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

Worked perfectly!

5 Stars

I could imagine a marine mechanic would not be pleased with the pump/tube, but I am! I saw other peoples reviews and that the pump was useless. I put a small hose clamp on the tube to the pump and tightened it just a bit. Slow, steady pumps and i had no issues. Gear oil change was done in less than 10 minutes from drain to fill. Great product. Just dont handle it like a caveman, its plastic. If you handle as it is intended, it works great.

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

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

Make sure you find and order the correct adapter for the lower unit. I was lucky and scavenged a spare piece of small tube to make it work.

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.

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

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