If the engine cranks slowly or fails to turn over, check the condition of the battery on the Five Battery Volt
Meter to the right of the helm. If the battery is low, you may have to run the generator for a short while to
charge the batteries. If so, see generator operations to start. After starting make sure you switch the charger
breaker on.
Move the THROTTLES to raise the engine speed to 700 rpm on the TACHOMETER. Check to make sure
water is being expelled from the exhaust at the stern. Warm the engine for about 5 minutes and reduce RPM
to idle before engaging transmission. Observe the readings of the gauges. The oil pressure will register
about 60 PSI. Cold engine temperatures should rise slowly after 10 minutes or so.
Note -- If oil pressure is low after 30 seconds, shut down engine, and inspect engine compartment and look
for possible cause (for example, loss of oil.) Caution -- If an engine is overheating or there is lack of raw
water expelled in the engine exhaust, stop the engine immediately. Recheck the raw water-cooling system to
ensure the seacock is ‘open’ (handle in-line with valve). Next, check the raw water strainer for debris.
Remove the strainer, clean, re-assemble, and reopen the raw water intake valve (seacock). Restart the
engine and re-check water flow from the exhaust. If water is not flowing properly, the RAW WATER PUMP
may need to be serviced. Seek help from AYC.
Shut-Down
Before shutting down, allow the engines ‘idle’ for about 5 minutes to cool them gradually and uniformly.
This is most important after a long run at top speed. The time engaged in preparing to dock the boat is
usually sufficient. Ensure each GEARSHIFT is in the ‘neutral’ position and each THROTTLE is in the ‘idle’
position. Turn off engines by pushing the STOP BUTTONS. When the engines stop the oil pressure
warning buzzers will sound. Turn off the engine power breakers and the STOP switch.
Getting Underway
Retrieve the boarding ladder and place in the lazarette. DISCONNECT the shore power cord (see 110-Volt
next page). Close the PORTHOLES, WINDOWS, and FORWARD HATCH. Turn on your VHF and
electronics. ASSIGN crew members their various positions. Once outside the marina and out of the traffic
lane, for crew safety, idle the engines while crew brings in fenders and lines.
Cruising
All close quarters maneuvering should always take place at the FLYBRIDGE HELM for the best visibility.
Engage the GEARSHIFTS. Ensure the throttles are in the ‘idle’ position before engaging the gearshifts to
avoid transmission damage. Cruising speed is a maximum of 2000 RPM. If you run at 7Kts or less, you
will use only 2-3 gallons of diesel per hour. We have found that cruising at or around 1650 RPM’s provides
a good speed and fuel efficiency. Your speed will vary depending upon the weight and load and weather
conditions.
