The plastic one won't last. This aluminum fitting is awesome. I highly recommend if you are doing your own out drive oil change. A ++++

Easy to use pump system. Screws right on top of a 1 quart bottle. Also comes with adapters to screw into lower unit.

After I put the pump in the quart bottle, I couldn’t get the plunger out so I could pump the oil out of the quart bottle. Removed it from the bottle and twisted it in the right direction and the plunger popped out like it should. Pumped great after that. The fittings are good as well, you leave the one on the hose and if either of the other two fittings are the one you want, screw it onto the one in the hose.

Used on a 74 Johnson outboard, took just less than one quart, go slow at the end because this thing will generate a lot of pressure as it pumps up the oil. I always put in the fill screw first and then the fluid wont leak out as fast when you put in the drain (this screws to the drain). Not sure the threads on the adapter were a perfect fit, but it was tight enough to pump up fluid,

Cover seems to be durable, time will tell.I have a 14’ 70” beam Jon boat and ordered this which covers 14’ to 16’.Was able to cover entire boat including the motor.Again time will tell hoping it last as good as it looks.

Just changed gear oil in lower unit (Yamaha 225) and it was very user friendly. I did have to use one of the fittings that was included so I was glad I ordered this particular item. If you are planning on doing maintenance on your boat motor you will need this tool. Pump works great and changing the gear oil is one of the easier things you can do to maintain your investment.

Just the ticket. I got rid of the plastic pump that came with the lube. This one is much sturdier.
