Starting Engine (Fuel Injected Engines) - PCM 2007 5.0L MPI Owner's Operation And Maintenance Manual

OPERATING INSTRUCTIONS - 5

STARTING ENGINE (FUEL INJECTED ENGINES)

WARNING
Before starting engine, ventilate the engine
compartment by operating the bilge blower for
a minimum of fi ve minutes to remove any gas
fumes from the engine compartment. If the boat
is not equipped with a blower, open the engine
compartment hatches to ventilate and leave open
while starting engine.
IMPORTANT: Do not start the engine without water
being supplied to the sea water pick-up pump or
sea-water pump impeller will be damaged, and
subsequent overheating damage to the engine may
result.
IMPORTANT: The following items should be
checked before starting the engine, and each time
the boat is operated:
• Fuel system for any signs of leakage
• Operation of remote controls and steering
• Engine and transmission oil levels
• Fuel tank levels
• Exhaust system for leaks and tightness of the
clamps
• Battery connections and water level in battery
cells
• Accessory drive belt(s)
• Cooling system for leaks. If equipped with fresh-
water cooling, check coolant level in recovery
bottle. Check for signs of water leaks at the
exhaust manifolds, risers and elbows (Figure 5-
2). If the water is leaking externally, it is possible
that the water is also leaking internally. This
could result in internal engine damage. It is very
important to service these maintenance items as
soon as a problem is indicated. After performing
the initial safety checks, proceed as follows to
start the engine:
1. Turn the battery switch ON (if equipped).
2. Open the fuel valve.
3. Open the seacock.
4. Place the remote control in Neutral position. The
transmission is equipped with a neutral safety
switch, which will not allow the starter motor to
operate unless the transmission is in neutral.

5. Do not pump or open the throttle when
starting the engine (Figure 5-3). The ECM
will automatically regulate the fuel and control
desired idle speed.
6. Turn the ignition key to the start position. When
the engine starts, release the key.
NOTICE: Engine idle speed is controlled by the ECM
and is based on the operating temperature of the engine.
Upon initial start-up, engine RPM will be slightly higher
and will automatically decrease as the engine operating
temperature increases.
7. In the event the engine becomes fl ooded,
ensure the Neutral Lockout is engaged and move
the throttle lever to a 100% open position (Figure
5-3). At this throttle position, the ECM will
command the injectors to deliver no fuel during
engine cranking. When the engine starts, return
the throttle lever back to the idle position.
NOTICE: Single lever throttle/shift handles use different
mechanisms to achieve Neutral Lockout or throttle only
operation. Some require you to push in on a button
while moving the handle forward, others require the
button to be pulled out. Refer to your boat owners
manual for complete instructions on throttle/shift lever
operation.
IMPORTANT: If the engine fails to start within 20-30
seconds, turn the ignition key to the OFF position
and allow 2 minutes for the starter motor to cool off
before attempting to restart the engine.
