I use a vacuum pump but I pull the dipstick slide tube out of the pan insert so I can stick a bigger piece of tube in there. Or you can do it like my friend and just pull the drain bolt and put a bucket by the plug. Then scrub all the oil out of the bilage.
Before I put the motor in my boat im gonna put a fumoto drain valve in place of the drain bolt and put a quick connect fitting on it that way all I have to do is lift the bow connect the hose and run it through the plug hole into a bucket.
