Gear Shifting - Mercury 50 4-Stroke Manual

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 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.
WARMING UP ENGINE
Before beginning operation, allow the engine to warm up at idling
speed for three minutes.

• Do not shift outboard into reverse when the engine is not
running.
