OPERATING INSTRUCTIONS - 5
• 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.
PCM has introduced a product enhancement feature on
all PCM Mulitport Fuel Injection Products. Your engine
may be equipped with the engine auto-crank feature.
This feature allows the engine to automatically crank,
or turn over, when commanded. Once the operator has
turned the key to the START position on a key switch, or
depressed the START button on a touchpad, the engine
will automatically turn over and start. The engine will turn
over until the engine starts, or a maximum of 5 seconds.
The key switch or stop button can always be utilized in
order to cease the engine from cranking and/or starting.
Important: In the event that the engine must be turned
over WITHOUT automatically cranking or starting (i.e.
bumping the engine to #1 position or performing a
compression check) a remote starter button MUST be
used, connected directly to the starter solenoid and the
ignition system disabled.

external leaks
The machinery space must be closed anytime the
engine is running to prevent injury to you or others
on board. Never operate the engine with the engine
machinery space open while someone is in the
machinery space, either closed or open. Never
open the machinery space unless the engine is shut
off and the engines rotating parts are stationary.
Rotating machinery can cause injury and even death
if an accident should occur. Extreme care must be
exercised if a problem exists that requires operation
of the engine with the machinery space open. IT IS
RECOMMENDED THAT UNCOVERED ENGINE
OPERATION BE ATTEMPTED BY TRAINED AND
QUALIFIED SERVICE PERSONNEL ONLY.
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.
