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.
NOTE: Engine can be stopped or running at idle speed when flushing the cooling system. Do not flush
