This step by step how-to-video will walk you through the process of changing the engine oil in a Mercury V-6 or V-8 four-stroke outboard engine. For more information, please consult a Mercury Marine owner’s manual or pop into North Coast Boating to ask any questions and to get your Mercury Engine Oil Changing items. Better still book your marine motor in for a service and we will do it for you.
