2018 Mercury Marine® FourStroke 150 HP

2018 Mercury Marine® FourStroke 150 HP

Massive displacement and the lightest 150 hp four-stroke in its class

Features may include:

Mark Ratchford is calling it his ‘huge adventure’ which might be an understatement - considering he spent four months on a solo 16,500 km (10,000-mile) circumnavigation of Australia in a 6.5 metre (21-foot) fishing boat powered by twin Mercury 150 FourStroke outboards.

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.

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.

Since its introduction to Mercury’s line of FourStroke engines, the 150hp has proved a valuable player in saltwater markets. Recently, Bernard Sweeting, an angler from Spanish Wells, St. George’s Cay, Bahamas, reported that his 150hp FourStroke reached more than 6,000 hours in commercial application, an impressive feat given the rough conditions that accompany commercial outboard use.

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.

Rather do it yourself? The no-spill oil-change system, an easy-access fuel filter and a lifetime maintenance-free valve train make the Mercury 150 FourStroke the easiest-to-maintain 150hp four-stroke on the market. Scan a QR code under the cowl to link with step-by-step video demonstrations.

The compact, lightweight design of the Mercury® 150hp FourStroke engine fits most transoms, including those with narrow engine wells and tight motor spacing. Rig it with mechanical or hydraulic steering, mechanical control and cable systems, and a full complement of analog or SmartCraft® gauges.
