Instrumentation; Analog Gauges - Mercury Inboard 5.7L Manual

Accidental or unintended activation of the switch during normal operation is also a
possibility. This could cause any, or all, of the following potentially hazardous situations:
• Occupants could be thrown forward due to unexpected loss of forward motion, a
particular concern for passengers in the front of the boat who could be ejected over the
bow and possibly struck by the propulsion or steering components.
• Loss of power and directional control in heavy seas, strong current or high winds.
• Loss of control when docking.
Avoid abrupt deceleration of the boat from lanyard stop switch activation. Boat damage
and personal injury or death could occur. Never leave the operator's station with the
engine operating and in gear.

The owner/operator should be familiar with all instruments and their functions. Because of
the large variety of instrumentation and manufacturers, you should have your boat dealer
explain the particular gauges and normal readings for your boat.
