Start Up WARNING In normal operating mode, the engine is started and stopped with the key switch. In an emergency situation, you can use the lanyard to kill all power to the engine. This will allow you to stop at once. Review the next pages to become familiar with the helm equipment. Place the control levers in neutral and turn the PORT ignition switch to the “On” position – but do not start the engine. The green control head light will illuminate. With the Control Levers in Neutral, check to see if the green light on the Control Head is solid or flashing. If flashing, push the “Select” button to select the head. The yellow light will now come on. Red Indicator Light Emergency Stop Switch.
Attach Lanyard Here. Potentiometer “Subthrottle” Redundant (Back-up) Throttle In the unlikely event that the throttle signal is lost between the helm mounted shift/throttle control head and the engine, the system is designed to revert to the redundant or subthrottle. First, the engine would reduce RPMs to idle speed, the digital display would show “Throttle Error,” and a small red indicator light would flash at the key panel. Directly below the red light is a small potentiometer (small, knurled knob) label “subthrottle.” Turn the knob all the way to counter-clockwise in order to take control of the throttle.
Then turn the knob SLOWLY to clockwise - the light will glow solid and you will have control of the throttle. When the signal loss problem has been corrected, you must shut the engine off and restart to return throttle control back to the shift/throttle control head.
