PROPULSION SYSTEM
3.9 ALARM DISPLAY
When the ignition button is first pushed to the ON position, you may hear an audible alarm
signal and see a “Stop Sign” appear on the Display, indicating that the diagnostic
function has registered a malfunction. Please refer to Volvo Operator’s Manual chapters
for detailed information about FAULTS and recommended action.
3.10 STOPPING
Put both engine controls in NEUTRAL. PUSH the Start/Stop button until the engine stops. If
unsuccessful, there’s a clearly labeled “Emergency Shutdown” button in the upper middle of the
engine.
Make sure to push OFF the Engine Ignition button and the Engine Battery Switches on the
electrical panel when leaving the boat.
Engine Stop & Restart after Crash-Stop If
the engine otherwise stops, the following
reboot procedure for re-start must be followed.
1. Put control lever in NEUTRAL
2. Acknowledge any ALARM
3. PUSH engine ignition button until all lamps have gone out.
4. Then TURN back on the ignition system (not the engine Start) position only.
5. Acknowledge any ALARM
6. START the engine by pushing the engine START/STOP.
7. STOP the engine, TURN OFF the Ignition. Wait again until all lamps have gone out.
8. RESTART the Engine.
3.11 OPERATING PARAMETERS
While it’s good to run the engine at top speed periodically for short periods of
time of 15 mnutes or so, “Max Cruising Speed” is about 200 RPM below full throttle.
3250 seems to work fine on ZING, producing a speed of 35 knots. While running, pay
attention to the engine gauges on the LCD display or read on the Raymarine data bar. A
significant change in oil or coolant temperature, oil pressure, or voltage should
nvestigated immediately before the engine is damaged.
OIL PRESSURE – Normally ______________________ except lower when idling
COOLANT TEMPERATURE – Normally 185 degrees F.
CHARGING – Normally 13-14 Volts when underway.
Depending on hull structure and engine installation, engine and hull resonance may be
greater at some speeds than others. This is normal and you will learn to pick the sweet
spots. If you hear any abnormal sounds, stop the engine and inspect.
If any warning lights or buzzers activate, stop the engine
immediately. Determine the cause and repair the problem before
continuing to operate.
