Flushing The Cooling System
Flush the internal water passages of the outboard with fresh water after each use in salt, polluted, or muddy water.
This will help prevent a buildup of deposits from clogging the internal water passages.
Use a Mercury Precision or Quicksilver accessory (or equivalent) flushing attachment.
NOTE: Do not run the engine while flushing the cooling system.
1. Remove plug and gasket and thread in hose coupling.
2. Attach a water hose to the hose coupling. Turn on the water gently and flush the cooling system for 3 to 5
minutes.
