9.9 HP CT Fourstroke
Equipped with a larger gear case for more thrust, the Mercury 9.9hp Command Thrust FourStroke delivers big-time power and control that wider, heavier boats demand. The Command Thrust gear case allows a wider selection of propellers to get the performance just right. So, if you're powering a barge, pontoon or heavier displacement hull, the 9.9hp is the perfect partner. Exclusive to Mercury and designed for easy control, the Multi-function tiller handle makes boating easy allowing gear shift, throttle, steer, tilt and stop the engine with just one hand. All recreational Mercury outboard models from the 2.5 - 350hp range now come with 3+3= 6 years of warranty coverage. World class engines, world class support, that's what you get when you buy a Mercury.
