Mercury 9.9MXLH FourStroke

Fitted with a 25 inch extra-long shaft, this used Mercury 9.9MXLH FourStroke runs the standard 9.9 hp gearcase rather than the Command Thrust upgrade, with manual tiller starting.

Specifications worth knowing

Gearcase ratio is 2.08:1 on a carbureted fuel system, with full throttle reaching between 5000 and 6000 rpm. Trim positions are ratcheting, and the exhaust runs through the propeller for quieter operation.

What to check before buying

Confirm the 25 inch shaft suits your transom before ordering; steering is tiller only here, with no remote-control rigging offered. Ignition is CDI with electronic spark advance, cooling is water-cooled with a thermostat, and the engine carries its own low oil pressure and over-rev warning system.

Who it suits

Boats with a taller transom that need the extra-long shaft, such as some utility, jon, aluminum tiller, and sail boats, where the standard gearcase is enough power for the job at hand. It is a straightforward fit for owners who do not need remote throttle and shift.

Condition notes

Dry weight is 84 lbs. Being a used motor, have hours and running condition confirmed with us before ordering, since wear differs unit to unit.
