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.
The raw water cooling system is described in detail in
your “Water Systems” (section 9) of this manual. The
internal engine cooling system is supplied by the engine
manufacturer. This system features a closed antifreeze
coolant bottled in a reservoir attached to the engine.
Coolant is circulated through the engine in separate
channels than the raw water cooling.
Note: Be sure the engine seacocks are open before you start
the engine. Failure to open them will cause damage to the
water pump impeller.
DANGER
!
!
burns or other personal injury when pressure cap is
removed. Allow engine to cool. Open pressure cap
slowly to allow pressure to vent before removing
cap.
11.1.5 Emergency Equipment
Your engines are set up to operate under the toughest
conditions. However, should the oil pressure become
too low, or the engine overheat, alarms will sound at
the helm. There are several conditions that will sound
an alarm and save you from damaging your engines.
Be sure and study your documentation supplied by the
engine manufacturer to ensure you will know what the
alarm means should one sound on your boat.
11.2 Transmissions
The transmission has a reduction gear which drives
the propeller at a slower rotation speed than that of the
engine.
Consult your OEM manual for complete transmission
information.
11.3 Operations and Maintenance
In the Underway Chapter, (Chapter 12) you will find
instructions on starting your engines. Also detailed in the
manufacturer’s documentation supplied with your boat,
you will find instructions on maintenance items that you
may perform yourself. Should you have any questions
regarding maintenance or operations not provided, be
sure and consult your boat dealer.
Important: Shift the transmission only when the engine speed
is at or below 1000 rpm. Shifting at higher engine speeds could
severely damage the boat, the transmission, and the engine.
Allow the transmission to remain in neutral for a few seconds
before reversing the rotation of the propeller.
