Open rear engine door. Look at the right lower corner of the door opening for a black rubber line with a hydraulic line cap on it. This is the drain plug. It is located here because the engine sits sideways and the normal plug cannot be easily removed. Just take two 19 mm wrenches and remove the cap, then remove the cap on top of the valve cover that says "oil" and allow about 30 minutes to drain, as it drains very slowly from the rubber hose drainage tube.
