FUEL SYSTEMS
IMPORTANT: Before the first start-up of your
new engine:
•
•
•
Read Engine Starting, Engine Stopping, and
Shifting and Speed Control.
Check the gearcase lube level. Refer to Lubrica-
tion.
WARNING
If your motor is equipped with a quick-dis-
connect fuel hose, disconnect the fuel hose
from the motor and from the fuel tank when
the motor is not being used for a period of
time. Disconnecting the hose will avert fuel
leaks in the hose or at the engine.
Perform prelaunch checks of all equipment.
Launch the boat and start the engine according
to the procedures in Engine Starting.
•
Verify water pump operation often. Look for a
steady stream of water from the water pump indi-
cator. If the stream of water stops, shut off the en-
gine to prevent damage. Find and correct the
cause, or see your Dealer before you continue.
IMPORTANT: Fuel distribution hoses in the boat
must deliver fuel at the rate of flow needed by the
engine. Minimum inside diameter of fuel hoses
must be 5/16 in. (8 mm).
Fuel systems with built-in tanks, particularly those
that include antisiphon valves and filter/primer
units, may have restrictions that will not allow the
engine fuel pump to deliver sufficient fuel under all
conditions. This can result in a loss of performance
and possible engine damage. If a performance
problem exists, see your Dealer.
• Verify shift function by shifting into gear and ob-
serving that the boat moves and that the move-
ment is in the same direction as the shifter. Refer
to Shifting and Speed Control.
•
Change the RPM often. Avoid holding a throttle
setting longer than 15 minutes.
1. First 10 Minutes of Operation

various speeds no faster than 3500 RPM.
DO NOT hold a constant throttle setting. Change
engine speed every 15 minutes.
— Operate engine in gear at
To avoid difficulty when restarting, never run the
engine with the fuel hose disconnected or run the
engine out of fuel.
With easy planing boats, use full throttle to quickly
accelerate boat onto plane. Immediately reduce
throttle to one-half as soon as boat is on plane. BE
SURE boat remains on plane at this throttle setting.
BREAK-IN (10 HOURS)
IMPORTANT: Follow this procedure to protect your
new outboard during its initial hours of operation. 3. Second Hour — Use full throttle to accelerate
boat onto plane, then reduce throttle setting to
three-quarters. BE SURE boat remains on plane at
this throttle setting.
Careful break-in allows internal engine components
to “seat” properly, resulting in maximum engine per-
formance.
Failure to carefully follow the break-in procedures
can result in engine damage.
During break-in, you must use extra oil. The fuel/oil
ratio for the first 10 hours of operation must be 25:1
(4% oil). The fuel/oil ratio during normal operation,
after break-in, must be 50:1 (2% oil).
Perform the 10-Hour break-in procedure with the
boat and engine in the water, using an appropriate
propeller.
DO NOT perform break-in using a flushing device.
DO NOT start-up or run the engine out of the water.
DO NOT leave a running engine unattended.
At intervals, apply full throttle for periods of one to
two minutes, returning to three-quarters throttle for
a cooling period.
Change engine speed every 15 minutes.
4. Next Eight Hours — Avoid
continuous
full
throttle operation for extended periods.
Change engine speed every 15 minutes.
DO NOT exceed recommended maximum engine
RPM. Refer to Engine Specifications.
