Mercury 9.9HP 9.9MLH CT – Manual 20in Shaft

Mercury 9.9HP 9.9MLH CT Manual Command Thrust

Engineered for high-displacement pushing power, the Mercury 9.9HP 9.9MLH CT utilizes a 208cc twin-cylinder architecture to deliver a high-torque solution for US boaters requiring a prop-rated propulsion unit with superior thermal stability. This 9.9HP four-stroke technology utilizes a Command Thrust (CT) gearcase and a larger-diameter propeller to maximize mechanical efficiency and lift for heavy pontoons and aluminum workboats. The 20-inch long shaft design provides an optimized center of gravity, while the manual recoil start and ergonomic tiller ensure immediate, reliable ignition without the need for an external battery.

Operational longevity of the 9.9MLH CT model is secured through a specialized pressurized lubrication system featuring a maintenance-free valve train to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a sophisticated carbureted induction system with an automatic enrichment feature, while the Mercury XK360 alloy science utilizes a multi-layer finish to mitigate oxidation. With a 3-year/300-hour service interval and an oversized gearcase footprint, this fuel-efficient outboard provides superior ownership value for users seeking high-thrust performance in a manual configuration.
