## Customer Reviews

### ⭐⭐⭐⭐⭐ Better than using drain hose
*by K***4 on October 16, 2023*

2004 Larson LXI with a 4.3 Mercrusier. Was using the supplied oil drain hose that I have to put through the drain plug hole that was very hard to get at. I observed that I had a threaded oil dip stick so I decided to purchase this to see if it was easier. It was much easier and less time consuming. Added a small hose clamp to the device to make sure I didn't have a leak. Couple of pumps to get the suction going, and away we go. No leaks, worked great. Used the left over anti-freeze jug to catch the oil. Just when your done with it put it in a plastic bag because the left over oil will drain out of it.

### ⭐⭐⭐⭐⭐ Works great
*by L***L on January 14, 2025*

Bought this to change the oil in my deck boat inboard motor. The pump worked great and i would recommend it for purchase.

### ⭐ Worthless Pump
*by K***S on May 19, 2025*

Really disappointed with the pump. It would not thread on to my Mercruiser 4.5L dipstick. I purchased this ahead of time to be ready for the season and did not try it until after the return window. If you decide to buy, make sure to try and thread it on as it may not fit. Really frustrating to purchase a name brand part and get knockoff results.
