Throttle/Shift Control - Grady-White 330 Express Owner's Manual

T /S
HROTTLE HIFT
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 aft 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. You may use the neutral lock out feature on the control handle to
increase the flow of fuel to the engine while remaining in the neutral position.
Neutral Lock-out Button
for Mechanical Shifter is
located on starboard handle.
Reverse the shift mechanism to stop a boat that is moving forward. This change in direction
will provide a "braking action" and slow the boat.
The braking action causes a wake which may wash over the transom and flood the boat if the
vessel is moving too fast. Allow engine RPMs to decrease before shifting into reverse.
If your boat has mechanical controls, there will be control cables that operate the shift and
throttle functions on the engine. If your throttle or shift cables need replacing, use the same style
and length as the original equipment.
