Review on 🚀 Efficient Quicksilver 802889Q1 Oil Drain Pump - Easy Drainage in One Size by Mike Davis

Good product, good job. Unlike electric, it requires little muscle power, count on 15 minutes of continuous pumping (at an odd angle). At the end of the process, a few drops of oil dripped from the top. But I think it has to do with the vacuum pressure in the tube when it's empty but there's still some oil in it. Much cheaper than taking the boat to the mechanic for a single fluid change. Would buy again but might look for an electric pump for ease of use.
