Title: Worked surprisingly well
Review: I previously used one of the electric ones to change the oil in my 4.3l Mercruiser engine and it was horrible. It took over an hour and then never worked again. Given the good reviews and low price of this hand pump, I gave it a try. To my surprise, it sucked all the oil out in less than 5 minutes. I was very impressed as to how well it worked. There's no priming or anything, just start pumping it and it moves the oil very quickly. I didn't even warm up the engine either and I run 20w50 oil in it! Highly recommend.
