How do you change oil on a mastercraft boat?

To change the oil on a MasterCraft boat, first ensure the engine is warm, as this helps the oil drain out more easily. Next, remove the oil drain plug from the bottom of the oil pan and allow the old oil to fully drain into a suitable container. Replace the drain plug, then remove the oil filter and install a new one, making sure to lubricate the rubber gasket with new oil. Finally, refill the engine with new oil through the dipstick tube, checking the level to ensure it's within the recommended range.
