automatically when within 200 RPM of each other.

Emergency Shifting If a fault occurs which prevents
electronic gear shifting with the control levers; it is
possible to shift manually using the procedure outlined
on page 56-57 of the VPOM.

SUDDEN MOVEMENT HAZARD


This control lever governs both throttle and shifting functions. The boat may start to move
abruptly when the marine gear is engaged: Ensure the boat is clear of all obstacles
forward and aft. Cautiously shift to the IDLE FORWARD position then quickly back to
NEUTRAL position. Observe whether the boat moves as you expect.


Before starting the engine, make sure (1) the raw water intake seacock over the IPS drive
flange is in the OPEN position (2) the raw water strainer is clean (3) the engine has
sufficient oil and coolant (4) transmission fluid is at the proper level (5) there are no
restrictions to the air intake grills (6) the fuel valves over the tanks are OPEN (8) the
HOUSE and BOTH ENGINE battery banks are turned ON (9) the throttle is in the neutral
position (9) no one is in the water near the boat and (10) all machinery space hatches are
closed.

3.8 STARTING

TURN ON ENGINES Turn the spring-loaded Ignition
Keys clockwise to the first detent a position

A long continuous beep indicates that the self-test
function has failed.

START ENGINES by holding one then the second Ignition Key to the right with pressure
to position III on the outer key rim, for several seconds until the engine starts. Note: If you
can’t hear the engines (These are quiet boats), look at the RPM on the display to see that it
climbs to 600-700. Then release the key so it springs back to position I. The engine will not

start unless the shift levers are in NEUTRAL. If repeated start attempts are needed, the key
must be turned back to position 0 first.

Never engage the starter motor (turning key hard to the right) while the

engine is running. This may damage the pinion and/or ring gear.


IF BATTERY VOLTAGE is low and you have difficulty turning over the engine, a
momentary. Parallel Switch is located next to two Engine Start Battery Switches on the
electrical panel belowdecks. By pushing this switch on, you add the capacity of the house
bank to the start battery. Once started, turn OFF the Parallel Switch. It is for emergency use
only.
