OPERATING INSTRUCTIONS - 5

STOPPING ENGINE

When returning to the dock, or whenever stopping
the engine, bring the throttle back to the idle position
and ensure the transmissions are in Neutral. After the
engine reaches idle speed, turn the ignition key to the
OFF position.
Before stopping the engine after extended high speed
operation, allow the engine to idle at 1200 RPM for 3
to 5 minutes to allow the engine to cool down before
shutting off the ignition.
After stopping the engine, complete the following:
1. Turn the battery switch OFF, if equipped.
2. Close the fuel valve.
3. Close the seacock.
4. Flush the cooling system if in a salt water area.

FREEZING TEMPERATURE OPERATION

If the possibility of freezing exists, the cooling system
must be protected after the engine is shut off to prevent
freeze damage to the engine. Refer to OUT-OF-
SEASON STORAGE for draining instructions.

OPERATION IN HIGH DEBRIS AREAS

If the boat is to be operated in high debris areas, a sea
strainer should be installed in the water inlet hose to
prevent debris from entering the cooling system. The
strainer used must be of suffi cient size to allow an
adequate supply of water for cooling the engine. A
minimum of 30 gallons per minute (114 liters per minute)
fl ow rate is required.

Synchronization allows single throttle handle operation
of both engines. When you are in Sync Mode, both
engines maintain the same RPM. The 'Master" engine is
controlled by the Master throttle handle and the "Slave"
engine is electronically controlled to the same RPM as
the Master engine.
Cruise Mode allows electronic control of the engines
at an operator selected engine speed. When you
are in Cruise Mode, both engines are electronically
controlled to maintain the desired RPM regardless of sea
conditions or maneuvers.
IMPORTANT: The electronic Synchronization/Cruise
system requires one engine to be designated as
a 'Master', and the other engine designated as a
'Slave'. The Master/Slave relationship is determined
by the installer during engine installation; therefore
if the installer does not identify which engine is the
Master, the Master must be determined using the
following procedure.
DETERMINING THE MASTER/SLAVE ENGINE
POSITIONS
For fi rst time operation of the Sync/Cruise Mode, you
may need to determine which engine is the 'Master'
engine and which is the 'Slave' engine. Perform the
following procedure in neutral gear, while secure in your
boat slip.
1. Ensure the Syn/Cru Mode switch is in the OFF
position.
2. Perform the engine starting procedure for both
engines. Refer to the Starting the Engine
procedure in this section of the manual.
