2019 Mercury 9.9 HP 9.9EXLH-CT Outboard Motor

The 2019 9.9EXLH-CT pairs an extra-long 25-inch shaft with electric start and Mercury's CommandThrust gearcase, built for boats where the transom sits deeper than a standard mount, such as taller pontoons or sailboat brackets set well above the waterline. Fit before anything else Extra-long shafts exist to keep the propeller fully submerged when the mounting point sits higher than usual. Measure your transom before ordering, since a 25-inch shaft on a shallow transom runs the gearcase too deep, and a short shaft on a tall transom will cavitate instead of pushing water cleanly. Why CommandThrust still matters here Gearing comes in at 2.42:1, matched to a larger four-blade aluminum propeller for low-RPM push, exactly what a heavier or wider hull needs from an auxiliary or kicker motor rather than from something tuned for speed. Tilt on this version is manual and ratcheting rather than electric, which keeps overall weight and complexity down compared with the power-tilt models in the same CommandThrust family. Operating it day to day Every control, steering, throttle, and shifting, sits on the single tiller grip, so running it with one hand while watching the water ahead is straightforward even at trolling speed. Electric start also means no cord to pull on a cold morning at the launch ramp. Common questions Is the tilt powered or manual? Manual, using Mercury's ratcheting system. What ships with the motor? The CommandThrust four-blade aluminum propeller comes installed.
