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 Procedure:
Models With Electronic Fuel Injection (EFI)
Note: Do not advance the fast idle lever (a) or throttle only feature (b) for starting.
The electronic starting system will automatically prime (choke) the engine and
increase idle speed for starting.
Turn ignition key to the START position. If engine fails to start in ten seconds, return
key to "ON" position, wait 30 seconds and try again.
Models With Carburetors
If engine is cold, advance the fast idle speed lever (a) or throttle only feature (b)
to an approximate halfway (1/2) setting. Turn ignition key to the ON position. If
engine is cold, push in on the key and hold in for 6 seconds to prime the engine
before cranking. Turn the key to START position and start the engine. If engine fails
to start in ten seconds, wait 30 seconds and try again. If engine begins to stall,
re-prime (push key in).
After starting, keep engine speed below 2500 RPM to prevent engine
over-speed.
Note: Starting Flooded Engine: – Advance the fast idle speed lever or throttle only
feature to the full maximum position. Without activating primer, crank engine for
10 seconds. Wait 30 seconds and repeat until engine starts. Immediately start to
reduce engine speed after engine starts.

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.
1
Your outboard has three gear shift positions to provide operation. Forward (F),
Neutral (out of gear) and Reverse (R).
2
When shifting, always stop at neutral position and allow the engine speed to
return to idle.
3
Always shift outboard into gear with a quick motion.
4
After shifting outboard into gear, advance the lever further to increase speed.

STOPPING THE ENGINE

5
Reduce engine speed and shift outboard to neutral position. Turn ignition key
to OFF position.

EMERGENCY STARTING – MODELS WITH
CARBURETORS
Note: Models with Electronic Fuel Injection cannot be started manually.
If the starter system fails, use the spare starter rope (provided) and follow
procedure.
When using emergency starter rope to start engine, the start-in-gear
protection provided by the remote control is inoperative. Make sure to set
the outboard gear shift into neutral to prevent outboard from starting in
gear. Sudden unexpected acceleration could result in serious injury or
death.
To prevent getting an electrical shock, DO NOT touch any ignition com-
ponent, wiring, or spark plug wire when starting or running the engine.
1
Remove flywheel cover.
2
Shift outboard to neutral (N) position.
3
Turn the ignition key to ON position.
