The oil drain plug for a 25hp 4-stroke Mercury outboard is typically located on the lower unit of the engine, near the bottom. It can usually be identified as a hexagonal or slotted plug. To change the oil, ensure the engine is cool, remove the plug, and allow the old oil to drain completely before replacing it. Always refer to the owner's manual for specific details and maintenance guidelines for your model.
