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.

Works great for Bravo 3 Outdrive
Great pump, works as advertised. Was surprised the shorter fill tube was long enough to empty a quart bottle and move to have a longer option. Three fittings are convenient. Strong pump power. Good value. Would buy again!

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

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.

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.
