The affordable, portable Mercury 9.9 HP Outboard motor with Command Thrust delivers power, thrust, and control that wider, heavier boats need. A larger prop increases control and a taller gear case puts the propeller deeper below turbulent water for improved power. The Mercury 9.9 outboard engine is the right choice for sailboat and kicker applications. The 96 lb. 9.9 HP Mercury Outboard Motor model 9.9MLH-CT is an affordable outboard equipped with a 20 inch long shaft and manual start, Mercury's 3 year factory warranty, auto ratchet tilt, and multi function tiller control.
