Need a replacement cover for your Yamaha outboard? This is the official Yamaha part (part number MAR-MTRCV-ER-SM, which has been superseded by the new number MAR-MTRCV-ER-10). It's designed to fit a range of Yamaha 4-stroke outboard motors from 6 to 30 horsepower, specifically models like the F9.9, F15, and others in that family. It's the durable, protective plastic cowl that covers the top of your engine, shielding it from the elements, dust, and minor impacts. Using a genuine Yamaha part ensures a perfect fit with all the proper mounting points and cutouts for controls. It comes as a single cover, ready to install. If your old cover is cracked, faded, or missing, this is the right way to get your motor looking and functioning like new again. Always double-check your specific engine model and year to confirm compatibility before ordering.
