ENGINE BREAK-IN PROCEDURE

CAUTION
Severe damage to the engine can result by not complying with the Engine
Break-in Procedure.
GASOLINE/OIL BREAK–IN MIXTURE
Do not use pre–mixed gas and oil during break–in. Oil from the oil injection system
will supply adequate lubrication during engine break–in.
Break-in Procedure
First hour
•
Allow engine to warm-up for 30-60 seconds.
•
Avoid continuous operation at idle speed for more then ten minutes.
•
Run the engine the majority of time between 3000 and 4500 RPM
approximately three quarter throttle.
•
Vary engine speed; change engine speed approximately every 2 minutes.
•
Avoid trimming the outboard out (up) beyond a vertical trim position during
operation.
•
Short bursts of full throttle for periods up to 10 seconds are acceptable.
Next three hours
•
Change engine speed every 10 minutes.
* Note: It is the driver's responsibility to always drive in a safe manner. Improper
trim angle of the outboard when driving at speed can be difficult and dangerous.
The purpose of specifying trim angle is to help guide the operator in determining
how to put the proper load on the engine. They are intended to be guidelines and
do not suggest or require unsafe boat operation.

STARTING THE ENGINE

Before starting, read the Pre-Starting Check List, Special Operating Instructions,
and Engine Break-in Procedure on the first three pages in the Operation Section.
CAUTION
Never start or run your outboard (even momentarily) without water circu-
lating through all the cooling water intake holes in the gear case to pre-
vent damage to the water pump (running dry) or overheating of the en-
gine.
1
Lower the outboard to the run position. Make sure all the cooling water intake
holes are submerged.
2
Open fuel tank vent screw (in filler cap) on manual venting type fuel tanks.
3
Squeeze the fuel line primer bulb several times until it feels firm.
4
Set the lanyard stop switch to RUN position. Read the Lanyard Stop Switch
safety explanation and Warning in the General Information Section.
5
Shift outboard to neutral (N) position.

STARTING THE ENGINE (CONTINUED)
Note: It is not necessary to use the neutral fast idle speed feature on the remote
control to increase engine speed for starting and warm up. The electronic starting
system will automatically increase idle speed for starting and will reduce it as the
engine warms up.The engine does not require you to actuate the primer (choke)
for starting. The electronic starting system will automatically prime the engine.
6
Turn the ignition key to START position. Release the key when engine starts.
If engine fails to start in 10 seconds, return the key to ON position, wait 30
seconds and try again.
7
Check for a steady stream of water flowing out of the water pump indicator
hole.
IMPORTANT: If no water is coming out of the water pump indicator hole,
stop engine and check cooling water intake holes for obstruction. No
obstruction may indicate a water pump failure or blockage in the cooling
system. These conditions will cause the engine to overheat. Have the
outboard checked by your dealer. Operating the engine while overheated
will cause engine damage.

GEAR SHIFTING

IMPORTANT: Observe the following:
•
Never shift outboard into gear unless engine speed is at idle.
•
Do not shift outboard into Reverse when the engine is not running.
8
Your outboard has three gear shift positions to provide operation. Forward (F),
Neutral (out of gear) and Reverse (R).
9
When shifting, always stop at neutral position and allow the engine speed to
return to idle.
10
Always shift outboard into gear with a quick motion.
11
After shifting outboard into gear, advance the lever further to increase speed.

STOPPING THE ENGINE

12
Reduce engine speed and shift outboard to neutral position. Turn ignition key
to OFF position.
