Chapter 4: HELM CONTROL SYSTEMS 4.1 General The helm controls consist of three systems: the engine throttle and shift controls, the steering system, and the trim tab control switches. These systems provide the operator with the ability to control the direction and attitude of the boat from the helm station.
Page 46 Helm Control Systems dicate that the control is activated and the engine can be started. The most common features activated or moni- tored by the keypad are: • Starter lockout, which prevents the engine from being started in gear. • Gear lockout, which allows the engine RPM to be advanced in neutral safely.
