Starting The Engine - Tiller Handle Models - Mercury 50 4-Stroke Manual

7. Turn ignition key to the "START" position. If the engine fails to
start in ten seconds, return the key to the "ON" position, wait
30 seconds and try again.
8. After engine starts, 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 will cause engine damage.
WARMING UP ENGINE
Before beginning operation, allow the engine to warm up at idling
speed for three minutes.
Starting the Engine ‑ Tiller Handle Models
Before starting, read the pre‑starting check list, special operating
instructions, and engine break‑in procedure in the Operation
section.
Failure to provide sufficient cooling water will damage the water
pump and cause the engine to overheat. Provide a sufficient
supply of water at the water inlets during operation.
