Re: Oil Changing Pumps
I had the same problem this year. I bought a "Sterns" electric pump from Wally World about 10 years ago. It's all I've ever used. This year, new boat, and it took 3 hours to get 3 quarts out of a warm engine. According to the engine specs, it holds almost 9.
I went online and checked out the reviews for pumps. I purchased the same manual "West Marine" pump as stated before. I wasn't able to warm the engine because it was 3 quarts low, and the oil filter was already removed, and it only took about 20 minutes to empty the oil pan.
I bought the larger of the two pumps. Worth the $70. I drained the oil into gallon jugs, and let the unit drain on its side overnight. It's back in the box, and ready for next year clean and empty!
The only thing I didn't like about using the garden hose fitting is that I was left with a puddle of oil around the tube caught in the fitting. When I replaced the dipstick, it gushed out and made a mess. I tried sopping it up with a paper towel, but I still didn't get it all. I was thinking about a rubber spacer or something for next year. I'll probably just use the large tube provided with the pump. I ran it through the dipstick tube to see if I could get any more oil out, but it just slurped (telling me it was empty).
