Open

The fuel cock has two open positions, one for
selecting fuel flow from the built-in fuel tank,
and one for an external tank.
Fuel flows to the carburetor with the lever or
knob in either open position. These are the
normal running positions.

EMU25911

Tiller handle

To change direction, move the tiller handle to
the left or right as necessary.

EMU25921

Gear shift lever

Pulling the gear shift lever towards you puts
the engine in forward gear so that the boat
moves ahead. Pushing the lever away from
you puts the engine in reverse gear so that
the boat moves astern.
