2018 Mercury 9.9 Hp 9.9ELH-CT Outboard Motor

At 103 lbs, this 2018 Mercury 9.9ELH-CT (SKU 9.9ELH-CT-18) adds Command Thrust to the 9.9 HP twin-cylinder platform: long shaft, electric starting, tiller control, and a BigFoot lower unit.

What Command Thrust changes

That BigFoot gearcase runs a 2.42:1 ratio and drives a larger high-thrust propeller, giving this motor more bite in the water than a standard 9.9, built for wider or heavier boats that need extra low-speed control. An oversized anti-ventilation plate keeps the prop loaded in rougher water, which suits sailboat and trolling or kicker duty where thrust matters more than top speed.

Specifications and warranty

A 76-watt alternator runs the electric starter on this build, with a manual pull-cord option tucked into the cowl as a fallback. Mercury's saltwater rating covers it, and ownership is backed for three years under the standard factory term. Match the propeller pitch to your boat's load rather than assuming the included prop is the only option.

Q: What does the Command Thrust gearcase change? A taller BigFoot gearcase and larger high-thrust propeller for more control on heavier boats.

Q: Is this a tiller or remote-steer motor? Tiller-steered, with starting, shifting, and throttle control all handled right at the tiller handle itself, not a remote console.
