STARTING THE ENGINE (CONTINUED)
WARNING
RAPID ACCELERATION HAZARD - Tiller Handle Models - 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.
11 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 Remote Control Models - When shifting, always stop at neutral position and
allow the engine speed to return to idle.
3 Tiller Handle Models - Reduce engine speed to idle before shifting.
4 Always shift outboard into gear with a quick motion.
5 After shifting outboard into gear, advance the remote control lever or rotate the
throttle grip (tiller handle) to increase speed.

EMERGENCY STARTING
If the starter system fails, use the spare starter rope (provided) and follow
procedure.

WARNING
When using emergency starter rope to start engine, the start-in-gear pro-
tection 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.
