Mercury 9.9 HP Command Thrust Fourstroke - Every Mercury engine, from the 400hp Verado to the 2.5hp outboard is built for reliability and dependability. Packed full of performance and reliability features, the 9.9hp Command Thrust is everything you need in an outboard.

More thrust to manoeuvre larger and heavier boats

The 9.9hp FourStroke Command Thrust “CT” delivers big-time power. With a longer design and larger components, the 9.9hp CT is engineered to deliver the type of power, thrust and control that wider, heavier boats demand.

A powerful kicker engine

The long shaft, lower gear ratio, and huge propellor relative to the standard 9.9hp outboard make this a professional kicker engine. Well suited to bigger boats with deeper hulls, the 9.9hp CT gives you more push in both directions and also comes with both electric and manual pull start.
