Stronger, Lighter, More Durable

Just call it bulletproof. The Mercury Marine 150hp FourStroke combines class-leading 3.0-liter displacement with a robust 4.9-inch gearcase. Nearly 10,000 hours of engineering and field tested proved the concept. We backed it with a three-year limited warranty. Just call it the best 150hp ever! Massive displacement and the lightest 150hp fourstroke in its class.

Perfect for Repower
Performance, Durability, Efficiency
Making 150 horsepower is easy for this 3.0-liter, four-cylinder, single-overhead-cam engine. Its generous displacement lets it churn out power without breaking a sweat. You get exceptional durability and long-term peace of mind.
Performance, Durability, Efficiency
Compact and Versatile
It's the lightest 150hp four-stroke outboard on the market. Smart design makes the 150hp Mercury FourStroke nearly 20 pounds lighter than its closest four-stroke competitor, and less than a battery weight heavier than a two-stroke. Potential uses for this engine are endless, including bay boats, boats with poling platforms and pontoons with swim platforms.
Compact Versatile
Propped to Perform
The Mercury Enertia propeller is the perfect complement to the 150 FourStroke. Designed specifically for large four-stroke outboards with a revolutionary low-diameter/high-blade-area design and cast with the Mercury proprietary X7 propeller alloy, Enertia delivers phenomenal acceleration, top speed and durability.
Propped to Perform
