2021 Mercury 9.9 HP ELHPT-CT Pro Kicker Outboard Motor with Command Thrust delivers the power, thrust, and control that wider, heavier boats need. A 20% larger prop increases control and a taller gearcase puts the prop deeper below turbulent water for improved performance. A low 2.42:1 gear ratio and high thrust propeller make the 103 lb. Mercury 9.9 outboard engine an excellent choice for sailboat and trolling/kicker applications. The Command Thrust over-sized, anti-ventilation plate prevents air from being drawn into the propeller, further enhancing efficiency and performance. The 9.9 HP Mercury Outboard Motor model: 9.9ELHPT-CT-PK is equipped with a 20-inch long shaft and electric start, power tilt, and Mercury’s multi-function tiller handle which allows one-handed operation of F-N-R gear shifting, throttle, and throttle tension, steering, and stopping.
