Helm Control Systems
During most operations of a twin engine boat, it
is advantageous for both engines to be operated
at the same RPM. This reduces noise, and vibra-
tion, and can increase engine efficiency. Setting
the throttles so that the engines are running the
same RPM (synchronized) can be done by listen-
ing to the engine sounds, with the synchronizer
feature built into some electronic engine controls
or with an optional engine synchronizing gauge.
Attempting to synchronize the engines solely by
using the tachometer readings or control lever
placement generally will not work. When the en-
gines are in proper synchronization, the throttle
levers may not necessarily be even. Please refer
to the engine or control owner’s manual for more
information on the features for the controls in-
stalled on your boat.
2.3 Neutral Safety Switch
Every control system has a neutral safety switch.
This device prohibits the engines from being
started while the shift levers are in any position
other than the neutral position. If the engine will
not start, slight movement of the shift lever may
be necessary to locate the neutral position and dis-
engage the safety cutout switch. Control system
adjustments may be required to correct this condi -
tion, should it persist. See your Monterey dealer
for necessary control and cable adjustments.
The neutral safety switch should be tested pe-
riodically to ensure that it is operating properly.
To test the neutral safety switch, make sure the
outdrives are tilted down and move the shift le-
vers to the forward position with the engines off.
Volvo Electronic Engine Control
compartment that operates the engine throttle
and transmission control lever. The controls have
a single lever for each engine that operates as a
gearshift and a throttle. General operation will
include a position for neutral (straight up and
down or slightly aft of vertical), a forward position
(the 1st detent forward of neutral), 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.
The control head key pad has integrated switches
and indicator lights which allow the operator to
control all aspects of the boat’s propulsion system.
The most common features activated or monitored
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.
• Battery voltage warning indicator that warns
the operator of high or low voltage supplied
to the system (audible alarm)
• An engine synchronization feature that
automatically keeps both engines at the same
RPM. Refer to Engine Synchronizing in this
section for more information regarding engine
synchronization.
These features and others not mentioned require
specific procedures to activate and operate them
properly. Some of the procedures and features
are unique to the engines, drive system and other
options installed on your boat. It is essential that
you read the owner’s manual for the controls and
be completely familiar with their operation before
using your boat.
