Gear Shifting - Mercury 4 FourStroke Manual

OPERATION
10. 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 may cause serious
engine damage.
