Lightweight, Compact Design
Mercury’s cutting-edge engineering has packed incredible power into a small, light package. A simple design with fewer parts than competitive engines. 40 lbs lighter than previous 115hp FourStroke.
Class-Leading Displacement
At 2.1 liters, or 126 cubic inches, this 4-cylinder SOHC design works less to produce more torque and horsepower! The large displacement design delivers optimum performance.
Optimal Torque Curve
Mercury’s 75-115 strong, low-end torque is what helps get the boat on plane instantly while delivering quicker acceleration. Also, as load increases, torque plays a big role in maintaining performance.
Performance-Tuned Scroll Intake
Compact and simple in design, the scroll intake uses a single throttle body and long intake runners to pack in more air to build torque. Top mounted for a more pleasing sound.
Low Friction Valve Train SOHC
Race proven “Roller Finger Followers” and oversized valves offer a less complex design. More reliability, more efficiency, and more power with lower cost of operation. To further reduce friction, specialized crankshaft oil scrapers & bearings minimize the amount of oil allowed to remain in the crankcase.
Multi-Port EFI
Pressurized low-maintenance fuel system.
World-Class Hydrodynamic STD Gearcase Design
All-New Standard gearcase possesses significantly higher hydrodynamic efficiency (less drag) vs. its predecessor. This gearcase delivers the best performance on lighter, performance-oriented hulls, such as aluminum or fiberglass bass hulls, flats boats, technical skiffs, and small-to-average weight deep-vees or runabouts.
Top Cowl Water-Separating Baffle System
Inner liners redirect any water entering through the rear air intakes down to exit through a pair of drain holes in the rear side area.
Focused Engine Mounting System
From the 150 hp evolution, Mercury’s 30° top angled and the lower oversized mounts minimizes crankshaft rotation inertia, reduces overall vibration, and improves durability for total control & comfort.
Digital or Analog Instrumentation
Operator kept conveniently updated on critical engine functions with this engine management system.
35 Amp Heavy Duty Stator
A three-phase system with a flywheel, dedicated stator, and water-cooled voltage rectifier/regulator. Compact and lightweight, it maintains the battery charge, especially at lower rpm speeds.
Idle Charge
With Mercury's low-voltage RPM strategy, the engine RPM will automatically increase if the battery voltage falls below 12V. The RPM will increase in increments of 25 RPM, up to a total of 100 RPM. Provides 48% more current at slower speeds to maintain the battery charge, all while supporting all your electrical components and accessories.
Tuned Idle Exhaust Relief
Based on the successful 150 hp FourStroke architecture, an acoustic filter weakens high frequency exhaust noise at idle speed, delivering whisper-quiet operation at low speeds.
