4. Shift & Throttle Control Head Functions
The Shift and Throttle Control Head comes with a dual function, single lever control. A single lever
control initiates both shifting and throttle for a single engine.
Refer to Appendix A for additional Control
Head operation information.
Control Head Operation
WARNING
The boat will start to move during the next steps.
Be very cautious when fi rst engaging the gears to establish that forward is truly forward
and reverse is truly reverse. A quick in-and-out of gear test is recommended.
Ensure that the boat is clear of all obstacles forward and aft before conducting this test.
With the engine running in neutral, the green and yellow control head lights are illuminated. Advancing
the control lever to the forward detent puts the boat in forward idle. Pushing it further forward increases
the throttle setting. The same is true in the reverse direction.
