Mercury 50 HP Command Thrust Fourstroke - Get more for less. The Command Thrust delivers the performance of a larger engine for less. Incredibly reliable and easy to operate, they’re the last thing you have to worry about on the water.

Take Your Outboard To A New Level

Get more thrust, power and control on broad-beamed and heavier fibreglass boats. With a prop that sits deeper in the water and a larger diameter propellor with 20% more surface area, you’ll enjoy better manoeuvrability and get on the plane at lower speeds.
