Mercury 9.9MXLH 9.9HP Command Thrust Manual 25″ Outboard Motor

Mercury 9.9HP 9.9MXLH CT Manual Extra Long

Designed for high-thrust auxiliary power and high-transom utility needs, the Mercury 9.9HP 9.9MXLH 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 internal gear set to maximize mechanical efficiency and lift for sailboats and heavy aluminum workboats. The 25-inch extra-long shaft design provides an optimized center of gravity for high-transom vessels, while the manual recoil start and remote configuration ensure immediate, reliable ignition without the need for an external battery.

Operational longevity of the 9.9MXLH 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 induction system with an automatic enrichment feature, while the Mercury XK360 alloy science utilizes a multi-layer finish to mitigate oxidation in high-salinity waters. With a 3-year/300-hour service interval and an oversized gearcase footprint, this fuel-efficient outboard provides superior ownership value for boaters seeking high-thrust performance and specialized vertical reach.
