Getting Underway
If the engine does not start:
• If the fuel filter has been changed or if the fuel system was
run dry, it will be necessary to cycle the ignition start button
from the STOP position to the START position several times
until the fuel pumps build adequate pressure. The cycling of
the ignition is necessary because the fuel pumps will run
only one to two seconds when the ignition is turned on,
unless the engine starts. Keep the shifter/throttle control in
NEUTRAL when starting the engine. If the throttle is
advanced, the computer will think the engine is flooded and
initiate a “clear flood” condition which will shut off fuel to
the engine and not allow it to start. The idle speed increase
is normally on hot or cold starts. This is programmed into
the computer. When the engine starts, the idle speed will
jump to approximately 1,500 rpm and quickly decrease to
between 750 and 900 rpm.
• Check for gasoline and cooling water leaks on the engine.
• Check for cooling water circulation (look at the raw water
strainer at the rear port side of the engine for water
movement).
Flooded Engine
If your engine does become flooded, use caution when attempting
to start the engine. Push in the transmission disengagement button
at the bottom of the shifter/throttle control handle and advance
the throttle to the FULL THROTTLE position. By pushing the
button in, the shift linkage is disengaged and the transmission
remains in NEUTRAL during the starting procedure. Run the
starter until the engine starts. DO NOT operate the start switch for
more than 30 seconds. Allow the starter to cool.
We suggest you bring your boat back to your Nautique dealer after
25 hours of operation for an inspection of the shaft alignment,
stuffing boxes adjustment, and the fuel system checked for leaks.
This is not a free service. Follow Pleasure Craft Marine’s (PCM)
recommendations in the maintenance section for additional
service to the engine. See your Nautique dealer to determine what
charges will apply.
