STARTING THE ENGINE – REMOTE CONTROL MODELS
6
Cold Engine – Move the neutral fast idle speed feature to the fully closed
position (a).
Warm Engine – Advance the neutral fast idle speed feature on the remote
control to the maximum fast idle speed position (b). After engine has started,
immediately reduce idle speed to normal.
Note: Cold Engine – air temperature is below 40°F (4°C) – After starting the
engine, slowly advance the neutral fast idle speed feature to increase idle speed
until engine is warmed up.
7
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.
Note: Starting Flooded Engine – Advance the neutral fast idle speed feature to
the maximum fast idle speed position and continue to crank the engine for starting.
Immediately reduce engine speed after engine starts.
8
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 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.
Warming Up Engine
Before beginning operation, allow the engine to warm up at idling speed for 3
minutes.

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
Open fuel tank vent screw (in filler cap) on manual venting type fuel tanks.

If the engine is cold, set the throttle grip to start position (a). If engine is warm
or flooded, set the throttle grip to position (b).
Note: Cold start – air temperature is below 40_ F (4_ C), After starting the
engine, slowly advance throttle speed until engine is warmed up.
7
Manual Starting Models – Pull the starter rope slowly until you feel the starter
engage, then pull rapidly to crank the engine. Allow rope to return slowly.
Repeat until engine starts.
8
Electric Starting Models – 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.
RAPID ACCELERATION HAZARD – Before shifting your outboard from
neutral into gear, decrease engine speed to slow. This will prevent a rapid
acceleration that can cause people in the boat to be thrown from their
seats or out of the boat, causing injury or death.
