WARNING
Do not attempt to service any engine or drive component without being totally familiar with the
safe and proper service procedures. Certain moving parts are exposed and can be dangerous.
CAUTION
Do not paint the outboard motors with anti-fouling paints designed for boat hulls. Many of
these paints can cause severe damage to the engines.
Steering
Your boat is equipped with electric steering with the Helm Master EX steering system. The
electric steering system does not have any hydraulic pumps or lines compared to conventional
steering systems. An electric motor directly moves and secures the engines. Most outboard engines
are equipped with an adjustable rudder trim tab. This trim tab should be adjusted to balance the
steering at the speed which you travel most frequently. Variations in speed, boat load or engine trim
will cause the steering to pull in one direction. If the boat pulls to the left, adjust the trim tab to the
left and vice-versa.
• Electric Steering:
The engine ignition panel must be ON for the steering to operate. There is no maintenance
required for the steering system. For emergency operation of the steering cylinder, loosen
the nut on the cylinder on the port side to manually rotate the engine. For any questions
regarding the steering system consult your 6X9 Steering manual or your dealer.
Throttle/Shift Controls
The throttle/shift controls located at the helm station control the flow of fuel to the engine.
They also act as gear shift levers to control the forward and reverse thrust of the propellers.
The middle position of the throttle control is the neutral position. Move the control forward to
engage the shifting mechanism which creates a forward thrust of the propeller. Advance the forward
movement to increase the fuel flow to the engine and boost the forward lunge.
Move the control lever aft of the neutral position to reverse the shift mechanism and create a
reverse thrust of the propeller. Increase the aft movement to increase the reverse thrust. Remember
that propellers are designed for maximum forward thrust; so, reverse thrust will not be as efficient.
All controls have a neutral safety mechanism. This mechanism will not allow the engine to start
when the control is in gear.
