Performance, durability, efficiency: Nothing is easier with this 3.0-liter, four-cylinder, SOHC engine delivering 150 hp. Its large displacement easily produces higher power. It offers exceptional durability and peace of mind for the long term.
Compact and versatile: The lightest 150 hp four-stroke outboard on the market. Thanks to its smart design, the Mercury FourStroke 150 weighs nearly 9 kg less than the closest four-stroke competitor and is barely heavier (the weight of a battery) than a two-stroke. Ideal for bay boats, pontoon boats with swim platforms, and other applications where space is limited.
The Enertia Advantage: Mercury’s Enertia propeller is the perfect complement to the FourStroke 150. Specifically designed for large four-stroke outboards and made from exclusive Mercury X7 alloy, the Enertia features a revolutionary low-diameter/high-surface-area blade design. It provides phenomenal acceleration, top speed, and durability.
Easy to maintain: Prefer to do it yourself? An oil change system with no spill, easy-access fuel filter, and lifelong valve control make the Mercury 150 FourStroke the easiest four-stroke 150 hp to maintain on the market. Scan a QR code under the cowling for step-by-step demo videos.
Perfect for repowering: The compact, lightweight design of the Mercury 150 hp FourStroke suits most transoms, including narrow engine wells and limited space applications. Equip it with mechanical or hydraulic steering systems, mechanical cable controls, and a full set of analog or SmartCraft gauges.
