then back to the neutral position, and try to start engine
again.
5. When engine is cold, run engine approximately one (1)
to two (2) minutes at fast idle speed (1200 to 1500
RPM).
6. Once engine has warmed up, check temperature
gauge to ensure engine temperature stays within opti-
mum range. If temperature reading is abnormally high,
stop engine immediately, and inspect for cause of
high reading.
7. With engine running, voltmeter should show a reading
between 11 and 14 volts.
8. Check steering operation. Turn steering wheel to full port
and to full starboard while observing outdrive movement.
9. Inspect for fuel odors and visible leaks in the fuel, oil,
coolant, exhaust, and power steering systems.
10. Make sure boat is still securely moored to the dock and
engine is idling at 600 to 800 RPM. Then move the
throttle forward and then aft, and back to neutral to
check for proper operation of the shifting motion.
To prevent excessive exposure and reduce the possibility of
CO accumulation in the cabin and cockpit areas of the
boat, the operator should provide adequate ventilation in
each of these areas. Utilize all hatches, doors, windows,
and side vents to increase air movement. See Section 1 for
information about Carbon Monoxide DANGERS.
Acceleration
Before bringing your boat “on plane,” check the entire area
to make sure you have a clear, safe path. As you throttle-
up and accelerate, your boat’s angle of trim increases and
causes the boat to ride bow-high. From a maximum angle,
the boat will level out to its planing attitude as you continue
to accelerate.
The maximum angle is commonly known as the “hump”. It
is advised to get over the “hump” as quickly as possible
due to limitations in visibility, handling, and performance in
reaching the maximum angle. It should only take a few
seconds at full throttle to get over the “hump”. At that point,
the boat reaches its planing attitude. After getting over the
“hump”, accelerate until reaching a comfortable plane,
then throttle down to cruising speed. This also will provide
for better fuel efficiency.

WARNING: Engine and generator exhaust systems
produce carbon monoxide (CO), a poisonous gas
which is odorless, colorless, and heavier than air.
Direct prolonged exposure can result in CO poisoning
that may be harmful or fatal. Indications of excessive
exposure to CO concentrations may include nausea,
dizziness, and drowsiness.
CAUTION: Acceleration at full throttle is not recom-
mended before the engine “break-in period” has been
completed. This “break-in period” also coincides with
the engine “twenty (20) hour check-up”. Therefore, full
throttle acceleration should not be attempted until your
engine has surpassed this usage time.
WARNING: Check behind you before coming off
plane Many accidents occur each year as a result of a
driver coming off plane ahead of a boat that is unable
to slow down in time to avoid collision.
