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 engine using a water
system that exceeds 310.26 kPa (45 psi).
