Kept things under control. A must have to fill the lower unit. Worked perfectly. Everything needed was in the box. Would buy again. A real saver.

Works as intended. Filled up my sea ray out drive with gear oil. Not sure how long it will last but it pumped 2 quarts.

Worked great for my mercury 60hp bigfoot. Fitting worked perfect and pump did what it should. Makes changing grease in the lower unit easy.

I can only get 1 or 2 turns on the 8mm adapter to my 88 Mariner 5hp motor. Wish I had a lathe to turn them down cuz the diameter is way to big. I'll hafta try a vise grip and take it to the grinder!!! Little disappointed here!!

I used this to change the oil in my Mercury outboard. Worked great, quickly pumps oil without leaking.Multiple thread adapters are included so it should be a one size fits all.I would recommend this product to anyone who owns an outboard and wants to do maintenance themselves. Just remember to pump from the bottom drain while the top plug is out.
