CAUTION
Avoid possible engine damage. If no water is coming out of the
water pump indicator hole, stop the engine and check the 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 authorized Mercury Marine dealer. Operating
the engine while overheated will cause engine damage.
Gear Shifting
IMPORTANT: Never shift into gear unless the engine is at idle.
Never shift into reverse without the engine running.
Your outboard has three gear shift positions to provide
operation: forward, neutral (out of gear) and reverse.

When shifting, always stop at neutral position and allow the
engine speed to return to idle.
Always shift into gear with a quick motion.
After shifting into gear, advance the lever further to increase
speed.
Stopping The Engine
Reduce engine speed and shift outboard to neutral position. Turn
ignition key to "OFF" position.
