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.
In addition to the primary helm controls, your boat
could be equipped with an optional bow thruster
that provides the operator additional control of
the bow while docking or anchoring the boat in
tight quarters or high winds and strong currents.
Each manufacturer of the control components
provides an owner’s manual with its product. It is
important that you read the manuals and become
familiar with the proper care and operation of the
control systems.
4.2 Engine Throttle and Shift Controls
The shift and throttle controls on your boat may
vary depending on the engines used. Refer to the
engine or control manuals for specific information
on the controls installed on your boat.
Electronic engine controls are standard on large
outboard engines. The following control descrip-
tion is typical of most twin and triple engine elec-
tronic control installations.
Electronic Engine Controls
The helm is designed for a binnacle style control
with a single lever for each engine on twin engine
installations. The port throttle lever controls both
the port and center engine on most triple engine
installations.
The electronic control system consists of three
major components: the electronic control head,
display screens and keypad, control processors
and applicable harnesses. The controls are com-
pletely electronic and there are no cables.
Twin Engine Controls
The controls have a single lever for each engine
that operates as a gearshift and a throttle. Gen-
eral operation will include a position for neutral
(straight up and down or slightly aft of vertical),

a forward position (the 1st detent forward of neu-
tral) and a reverse position (the 1st detent aft of
neutral). Advancing the control lever beyond the
shift range advances the throttle in forward or
reverse. Each control is equipped with a means of
permitting the engine to be operated at a higher
than idle RPM while in neutral for cold starting
and warm-up purposes. The control levers are
equipped with adjustable control head detent and
friction settings.
Triple Engine Controls
Yamaha triple engine installations utilize a two
handle control that operates very similar to the
twin engine control. A selector switch allows the
operator to select which engines provide forward
and reverse thrust, for optimum boat control and
handling. Individual engine trim switches are
