FourStroke 115 EFI Command Thrust: Large and in Charge

Need more muscle? Upgrade to a Command Thrust model with its larger gearcase and 2.38:1 gear ratio. Paired with Mercury’s V-6-class big-diameter propellers, these new 100 - 115hp FourStrokes deliver even better acceleration, awesome maneuverability and superior stopping power.

High Displacement

Displacing 2.1 liters, these FourStroke outboards produce power to spare, which leads to improved durability, longer life, greater hole shot, increased overall acceleration and awesome top speed.High displacement with Command Thrust attributes results in ultimate performance.

Improved Acceleration

The larger “CT” gearcase provides more leverage to lift heavier hulls onto plane and keep them on plane at lower speeds.The 2.38:1 gear ratio lets the engine spin up more rapidly, developing torque at a faster rate.


For the first time, Mercury is offering a 115hp FourStroke with left-hand rotation.The addition of a counter-rotation model provides neutral steering feel and superior handling in a twin-engine rig.Two 115 Command Thrust engines on the transom provide the maneuverability and get-home safety of higher-horsepower twins – at a much lower price.
