There is a hose that comes out of the bolt where the drain plug is on the back of the oil pan. That hose is about 2 feet long and has a brass fitting at the end. When I take that fitting off will my oil drain out, or will it have to be sucked out? Thanks Dan
You can push that hose through the bottom of the boat and let it drain as long as it will reach your drain hole.

Be sure to run the engine first in the driveway or do it when you get home from the lake, while it's still hot.
make sure that you don't put it in gear in driveway while it is warming up also. Not good for the strut bearing.

Run it on the fake lake (hose) to operating temp then promptly drain. I've used a drill pump if I was in a hurry.
What Maristar do you have? I've got a 90 240sc w/ the HO454.

Last thing. Once you've run it and dropped the hose through the drain, open the oil fill cap on the block or it won't drain very well.

I just finished. That was an easy job. That tube made it such an easier job than anticipated. However I was told a 454 take 7 quarts of oil, which is what I put in. I went to put the old oil into the empty quart bottles, and I had enough to fill 8 quarts. Was my oil level high with 8 quarts, or do I need to add another quart to the 7 I already added?

You need to check the oil level on the water. That's what's considered "level."
