Controls The shift function and engine speed control are combined in one lever. If necessary the shift function can be easily disengaged so that only the engine speed (rpm) is affected by the lever. The control lever has an adjustable friction brake. A neutral position switch is available as an accessory, this will only permit the engine to be started with the drive/reverse gear disengaged.

Maneuvering Shifting and engine speed are controlled with the same lever (1).

Lift the cover over the control. For side-mounted controls the lever must first be removed.

Set the lever to the half-open throttle/reverse position.

Adjust the friction brake. Turning the screw clockwise (+) makes the lever movement stiffer, while turning counterclockwise (-) makes it easier to move the lever.

Reinstall the cover and lever.
