primary chart plotter. If both units are on it creates a low voltage condition and one or both units
may not be fully functional.
Turn on a VHF radio. (two VHF radios are installed)
1.
Check the weather channel.
2.
Turn on Channel 16.
GETTING UNDERWAY
Make sure that the
shift lever is in the neutral position
.
Turn the start key to ON
. An alarm will sound (low oil pressure). Wait for the engines air heater
to preheat the air. The voltmeter will drop below 12 volts while the system operates (about 15
seconds). When the voltage returns to 12 volts the preheat cycle is complete. (The oil light may
come on but should go out once you start the engine.)
When preheating is complete,
push the START button while the key is in the ON position
to
start the engine.
Note: “Do not crank engine for more than 30 seconds, wait 2 minutes to allow
the starter motor to cool down before restart attempt.”
Let the engine idle
for about 5 minutes or until the engine coolant temperature gauge reads above
100.
Note: During warm-up at idle, the voltmeter will register about 12 volts. The temperature
indicator will not show any indication of heat until the engine has been running for several
minutes. Keep the engine below 1000 RPMs for five minutes, as the preheater cycles on and off as
needed during this time period. RPMs over 1000 block the preheating function.
Turn on the bow thrusters
by pushing the 2 ON buttons simultaneously. The amber light
between the buttons will come on. Toggle the joysticks momentarily in both directions to
ascertain that the thrusters are functioning properly.
1.
The thrusters are used primarily in maneuvering at or near the dock. In open
water while underway, the thruster is not effective.
2.
The thrusters will turn off automatically after a period of non-use. Restart in the
same manner.
3.
The thrusters may overheat and stop after 3 minutes of continuous running. After
a brief cool-down period, they will reset.
4.
If a thruster is inoperative, check the large red shut off switch in the lazarette for
the (stern thruster) or the red shut off switch located under a panel beneath the
mattress in the master stateroom for the bow thruster.
Check wind and current directions.
Use the thrusters to control the movement of the bow and stern while operating the throttle in
short applications of forward or reverse, pausing in neutral, as you maneuver in the marina.
Note:
when using reverse
, the
STERN WALKS TO STARBOARD.
CRUISING
When clear of the marina, make sure all mooring lines, fenders and anything loose are stowed.
Operate the engine at 1000 rpm for warm up. (5min.)
1.
After a 5 min. warm up operate the engine no faster than 1300
rpm until the coolant
temperature reaches 140 degrees. You will probably operate at 1100 to 1350 rpm, as this
is very economical and quiet. 1350 rpm is the “sweet” spot. Above that setting fuel burn
goes way up without much corresponding speed increase.
