Handle Throttle Speed Controller
A hand lever that sets speed on a Caroute drive — the throttle for E, S and W platform installations that have no tiller of their own.

What It Is
The E and S platforms ship without a throttle, and a W platform boat may want speed control separate from the wheel. This lever fills that gap: one hand on the handle, infinitely variable speed forward and reverse.
Caroute is explicit that it is an optional part for its own brushless electric motors, suitable for the E, S and W platforms and not suitable for other brands of motor.
Why It Is Specified
- Speed control where there is no tiller
Covers the E and S platforms, which are supplied without one.
- Fits three platforms
Listed as suitable for the E, S and W platforms.
- Lever action
A handle rather than a rotary knob, for gloved and wet hands.
- Optional part
Ordered only when the installation needs it.
Application Scenarios
- Owners repowering with an E platform drive.
- DIY builders finishing an S platform installation.
- W platform boats that want the throttle away from the wheel.
What It Fixes
- An engine-mount drive arrives without a throttle
This is the Caroute hand throttle for those platforms.
- Generic throttles do not match the control signal
Caroute states this part is not suitable for other brand motors.
- Console space is limited
A handle throttle mounts where the hand falls rather than needing panel area.

How It Compares Within the Range
| Option | What is different | Best suited to |
|---|---|---|
| Handle throttle | Hand lever | E, S and W platforms |
| Side mount throttle | Console side mounting, 10K waterproof potentiometer | Caroute brushless motors |
| PWM control | Signal input | Controller-driven installations |
How to Specify and Fit It
Confirm your platform is E, S or W.
Mount within comfortable reach of the helm position.
Check full travel gives full forward and full reverse before the first run.
