I have a 1987 Malibu Skier. It has a 351 direct-drive engine (that's what they say). I want to do my on tuneup and oil change. Do you have to get a pump to pump the oil or can it drain down the hull to the center drain plug of the hull. Also, what else should I do besides oil change and spark plugs. I am pretty much inclined to do anything with proper instructions. Thanks,
