OPERATION
58 eng
NOTE: The electronic starting system will automatically prime
(choke) the engine and increase idle speed for starting.
9. 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. This condition will
cause the engine to overheat. Have the outboard checked by
your dealer. Operating the engine while overheated will cause
engine damage.

When shifting, always stop at neutral position and allow the
engine speed to return to idle.
Always shift outboard into gear with a quick motion.
