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: You can have the outboard tilted or in the vertical operating position during flushing.
1. With the engine turned off, place the outboard in either the operating position (vertical) or in a tilted position.
2. Disconnect the flush connector from fitting on the bottom cowl.
