Review on 🚤 Convenient and Efficient: Shoreline Marine Pump for All Your Watercraft Needs! by Mike Burnett

I have a 20hp Mercury outboard. I didn't need the included adapter, but since I was a rat I kept it in the back of my tool box. This pump works perfectly without leaks and allows very precise lubrication with minimal loss. I installed a pump and a quart of oil so I could see the oil level in the bottle. I then pumped oil into the bottom block until I had nearly 12 ounces. Power is specified in the user manual. At this point I pumped more slowly until the oil came out of the top vent. I found this process more efficient than using a tube or bottle of gear oil. I wish you success.
