Performance & Practical Benefits

The first thing you notice when you pick up this cover is the material—it has that sturdy, rugged feel, the kind that makes you trust it right away. The Polysoft II lining is soft to the touch, designed to rest gently against the engine so it doesn’t leave marks or wear spots on the cowling. It’s the difference between a cover that merely sits on your engine and one that truly protects it.

Once it’s fitted, the cover hugs the shape of the 150 FourStroke cleanly. There’s no awkward bunching or loose fabric that catches the wind. It sits smooth and secure, whether the boat is getting hauled to the lake, sitting in salt air at the marina, or tucked away at home. The breathable, waterproof balance keeps rain out but allows trapped moisture to escape, helping prevent mildew and damp buildup beneath the cover.

The Polysoft II fabric also holds up incredibly well through long seasons of sun and spray. When you pull the cover off before a day on the water, your engine looks the same as you left it—clean, bright, and protected from abrasive dust, bird droppings, ultraviolet exposure, and road grit. It’s one of those small investments that pays you back every time you uncover the engine and see how well it’s been preserved.

Why Buy OEM

Mercury’s Tow N Stow covers are engineered for real conditions—not “universal” setups or one-size-fits-most shapes. This is a true OEM part with a fit made specifically for the 150 FourStroke cowling, down to the contours and taper of the engine. Aftermarket covers might appear similar, but they rarely fit as cleanly or last as long. Mercury’s materials, stitching, and lining quality stand up to harsh environments and frequent use. If you want long-term value and dependable protection, OEM is the way to go.
