3.After checking the DC gauges, then start the engine
with the start switch.
4.Once the engine starts and the oil pressure builds, the
alarm will cease. If the alarm does not cease, shut down
the engine and check your oil levels. If normal, seek the
help of a professional mechanic.
WARNING
!
!
In order to prevent premature fuel pump failure, do
not continuously crank engine starter for more than
10 seconds.
5.As the engine warms, the temp gauge will start to rise.
Watch the gauge and make sure that the engine does
not run hot.
6.Once the engine comes up to operating temp (check
manufacturer’s recommendations for correct tempera-
ture), move the shift lever to Fwd and Reverse to make
sure that the transmission will engage.
7.Now, shut down the engine and recheck your oil and
transmission fluid levels.
WARNING
!
!
DO NOT remove cooling system filter cap when en-
gine is hot. Allow to cool and then remove pressure
cap slowly, allowing pressure to vent. Hot coolant
under pressure may discharge violently.
WARNING
!
!
Exhaust gasses contain Carbon Monoxide. This is
a poisonous gas and can cause death. Shut down
engine immediately, if any exhaust leaks are de-
tected.
Important: Always be careful when starting the engine. Use
common sense and good judgment. Shut down the engine
immediately if you observe any unsafe operating conditions.
Important: If engine fails to start within 10 seconds, release
switch. Allow starter motor to cool for at least 60 seconds, then
try starting the engine again.
Note: Should there be a problem with the battery voltage level,
see the section in this chapter for emergency operation.
12.3 Getting Underway
WARNING
!
!
Before ever pulling away from the dock, make sure
that the shore power cord and the fresh water hoses
are disconnected.
Check that the fresh water tanks are full.
Verify that you have up to date fire extinguisher and
flares.
Make sure you have the required safety equipment for
your passengers.
After the engine reaches operating temperature, acceler-
ate the engine to 2000 RPM’s. Check that voltmeters
read 13 to 14.5 volts.
Check wind, tide, and current to determine the best way
to maneuver your boat away from the dock. Cast off
mooring lines.
Shift your boat’s engine into forward or reverse, depend-
ing on whether you want to move the bow or the stern
away from the dock first. Your engine should be running
at a slow speed as you move away from the dock.
Once your boat is in open water, you can safely acceler-
ate to cruising speed. Advance throttle to setting which
provides your desired engine speed (RPM’s).
12.3.1 Boat Handling
The best method to learn how to handle your boat and
get the best performance is to practice and experiment.
After several hours of operation, experiment with throttle
settings to find the setting that will be the most comfort-
able and economical range for your particular loading
conditions.
We suggest that you make a speed/rpm chart to deter-
mine the most economical operation. Operate your
boat at various speeds and check the fuel consumption.
Determine the amount of operating time remaining when
the fuel drops below ¼ full. Make a log of this type of
information and have it available when operating your
boat.
In addition, you should determine the following:
