2017 Mercury 9.9 HP 9.9MH Outboard Motor

Mercury's 2017 9.9MH is a short-shaft, pull-start 9.9 hp motor built for small craft that sit low to the water, rather than for boats needing a deep-reaching shaft or added low-speed thrust at the prop. Shaft length decides the fit The 15-inch shaft suits jon boats, skiffs, and compact pontoons, or light auxiliary duty on a sailboat that wants simple power without wiring in a battery or charging system. On anything with a taller transom, the propeller would sit too shallow to push properly, so measure before buying rather than matching by boat type alone. Standard gearcase, not CommandThrust This model turns a 2.08:1 ratio gearcase with a three-blade aluminum propeller, 8.5 inches across and pitched at 8.0 inches, the standard setup rather than the larger four-blade CommandThrust unit used on heavier-duty 9.9 variants elsewhere in Mercury's lineup. No battery needed to run it Starting and tilt are both manual: a pull-cord starter and a ratcheting tilt lever, so there's nothing electrical to wire in or maintain. The tiller carries throttle and shift control along with steering, all in one grip you operate with a single hand. Common questions How is it started? By pull-cord, manual start only. Is tilt manual or power? Manual, ratcheting tilt. Will it handle salt water? Yes, it carries a saltwater rating.
