2018 Mercury 9.9 Hp 9.9ELHPT-CT-PK Outboard Motor

Mercury's 2018 9.9ELHPT-CT-PK is the long-shaft, electric-start 9.9 built around the CommandThrust lower unit, meant for boats too wide or heavy for a standard-ratio kicker rather than for light, fast tillers skimming across open water.

Who it suits

Steering, throttle, and gear shifting all come from the tiller grip, a layout common on sailboats running this as auxiliary power and on backup motors where the main helm stays busy with something else entirely. Electric start and power-operated tilt mean raising or lowering the motor doesn't require leaning over the transom to work a lever by hand each time.

Fit first

The shaft measures 20 inches, sized for standard transom heights; mount it on a boat built for a different length and the propeller sits at the wrong depth either way, shallow or buried. Confirm your transom before ordering rather than matching by horsepower or boat type alone.

What CommandThrust changes

A 2.42:1 gearset turns a larger four-blade aluminum propeller here instead of a smaller standard one, trading some top speed for bite at low RPM, which suits trolling and holding position more than quick runs across open water. The build is rated for saltwater use and manufactured in Japan, so corrosion resistance is part of the design rather than an afterthought.

Common questions

Does a propeller come with it? Yes, the CommandThrust four-blade aluminum propeller ships installed on the motor.

Can it run in salt water? Yes, it carries a saltwater rating from Mercury.
