i don't know what type of engines you guys have but on my MasterCraft theres a 3ft Oil drain line that's attached at the drain plug on the Oil Pan (351 Cleveland), the hose is long enough to go out through the drain plug in the Hull i just push the hose out the drain plug hole and drain the oil from the outside under the hull, you should be able to find the oil draining kit at most auto parts stores, it saves a heck of alot of time and makes no mess at all.
