Well Made and Perrfect for Mercury Engines
Used this pump to fill my Mercury Verado lower unit with gear oil. The cap did not fit the oil canister which was not a standard quart but that did not matter. The 10 mm tip was the ideal fit for my engine. It was as easy as plug and pump. Worked out great and even easier as the tip can be turned easily to place it well fitted onto the hole. Made for easy work. Definitely recommend this item. Well made and works great.

Great product
Works great. Wish there was a way of clearing excess fluid from hose once done.

Works like a charm.
Used this product to replace lower unit gear case oil on 2-stroke Yamaha 175 and it worked like a charm. 28 mm fit the quart bottles I used and the included adapters made a perfect seal to the motor for a very easy and clean process. Product doesn’t feel heavy duty but is fine for DIY.

Know your hole size
Item as described. Pump worked great except that the fittings did not fit my volvo I/O bottom unit. Not the end of the world. Was still able to fill from the bottom with minimal oul leakage and was able to top off using the oil dipstick hole.

Good pump and seller

Great product for the price
I purchased this item to change the rear differential fluid in my 2014 Camaro SS. With the exhaust being in the way this product made it very easy to fill the differential back up. The tip fit perfectly in the fill hole. Each pump was a nice amount of fluid, you can see it going pretty quickly. I had no issues no leaks. It made the job a lot easier. I would highly recommend this product to anyone doing a differential fluid change.
