2017 Mercury 9.9 HP 9.9ELH-CT Outboard Motor

This 2017 Mercury 9.9ELH-CT (SKU 9.9ELH-CT-17) carries Command Thrust on Mercury's 9.9 HP twin-cylinder engine: a BigFoot lower unit replacing the standard gearcase, long shaft, electric starting, and tiller control. Built for heavier boats That BigFoot unit spins at a 2.42:1 gear ratio, deeper and taller than a standard-duty gearcase, paired with a larger high-thrust propeller and an oversized anti-ventilation plate. Together they push wider or heavier hulls harder at low speed than a standard 9.9 HP motor manages, which matters for sailboat auxiliary power or kicker and trolling use. Specifications before ordering A manual backup rides in the cowl alongside this build's electric starter, fed by a 76-watt alternator. Saltwater duty is fine under Mercury's rating, and the sale date starts a three-year run of factory protection. A fresh spark plug helps cold starts on a small twin like this. Q: Does this ship with a standard aluminum propeller? No, it comes with a 4-blade high-thrust propeller matched to the Command Thrust gearcase. Q: Why choose Command Thrust over a standard 9.9? The BigFoot gearcase and larger prop give heavier boats more push at low speed. Q: Is this motor tiller- or remote-steered? Tiller-steered, with electric starting and shifting handled right at the handle. Compare it with other Mercury outboards built with Command Thrust.
