Service your outboard with ease and with the proper servicing device
The pump works perfect for servicing the lower end of your outboard. The fittings provided are a plus in the servicing process. The pump is durable and made with quality. The item was accurately described and the price was great for what you get. Made the job fast and clean with no mess or leakage. The pump was fast and had the power to remove the oil from the container and transfer it to the motor. Extremely satisfied

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.

CHANGE LOWER UNIT OIL WITHOUT LEAVING AIR POCKETS
This is a must have for changing the lower unit gear oil on outboards without worrying about leaving air pockets. It makes it very easy to pump from the lower drain plug and provides the necessary attachments to fit most drain plug threads. The pump screw cap was too small to fit my gear oil bottle but I was able to hold it in place and pump the oil anyways.
