DANGER
! !
When occupying the engine room, or any area that
mechanical equipment may be located, always be
aware of moving parts or components. Death or
dismemberment may be the result of being caught in
moving machinery.
Important: Engines require air to operate. For this reason, do
not operate the engine or generator with this area obstructed.
Important: The engine manual supplied by the manufac-
turer includes complete and detailed information about oper-
ating and maintaining your boat’s engines. Be sure to read
it. Do not start or operate the boat’s engines until you
have done so. The life and performance you receive from
your engines depends greatly on the way you care for it.
11.1.1 Engine Mounts
The engine mounts supplied with your boat are manu-
factured by the engine manufacturer. These mounts are
designed specifically for the engine in which they are
attached.
Most engine mounts are designed for adjustment side-
ways as well as vertical. Vertical adjustment nuts lock
up or down on the threaded vertical stud, with a slot
provided to allow side to side adjustment on the engine.
Important: It is advisable to spray a protective coating on the
studs to prevent corrosion.
Many factors warrant the size and type of engine mounts
that are used. These mounts also contain isolators which
isolate the engine from the boat or stringers to dampen
vibration, noise. and other undesirable effects from
engines. For more information about the engine mounts
see the engine manufacturers manuals.
11.1.2 Engine Controls
The engine controls on your boat are located on the
steering pedestal.
The straight up position is neutral, shift forward to go
forward, moving further forward increases the speed.
Move the lever backwards for reverse, the same as for-
ward more movement in the reverse direction increases
the engine speed.
Press and hold the center button on the shift lever, and
move the lever forward to increase the engine RPM
without shifting into gear.
11.1.3 Engine Monitoring
CAUTION
! !
Always monitor your boats oil pressure, and
water temp. while underway, even if your
engines are equipped with an alarm system to
monitor these.
Shut down the engines immediately if the gauges
are not in normal ranges or an alarm sounds.
Do not restart your engines until the problem is
corrected.
For information on the correct levels for engine running,
please consult your engine owner’s manuals from the
engine manufacturer in your owner’s packet.
Important: The Hour meter will run if you leave the ignition
switch on when the engine is not running. This unnecessarily
increases the number of engine hours.
Note: Instruments have a tolerance for accuracy. In addition,
each engine may operate at differing values at the same RPM.
As long as the instruments are reading within the proper operat-
ing range, the engine is operating properly.
11.1.4 Engine Cooling
There are two separate systems that cool your engines.
