2017 Mercury 9.9 HP 9.9ELHPT-CT-PK Outboard Motor

The 2017 9.9ELHPT-CT-PK pairs a long 20-inch shaft, electric start, and power-operated tilt with Mercury's CommandThrust gearcase, aimed at wider or heavier boats than a standard-ratio 9.9 would comfortably push along.

Where it belongs

Steering, shifting, and the throttle twist all live on the tiller grip, a setup favored on sailboats using this as auxiliary power and on kicker motors where the main helm stays open for other tasks. Power tilt raises the lower unit electrically rather than by hand, which is worth having if the motor gets tilted up and down often during a day on the water.

The CommandThrust difference

Running 2.42:1 gearing, it swings a larger four-blade aluminum prop for extra thrust at low RPM rather than top-end speed, which is the point of a trolling or auxiliary motor rather than a primary one built for quick runs. Saltwater-rated construction and manufacture in Japan round out the build quality here.

Buying considerations

Because the power tilt adds weight and complexity over a manual lever, check that your boat's electrical system can support it before ordering, and keep the transom measurement handy so the long shaft lands at the right depth.

Common questions

Is the propeller included? Yes, a CommandThrust four-blade aluminum propeller ships with the motor.
