Refer to Storage procedure. See Storage section.
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.
IMPORTANT: The engine must be run during flushing in order to open the
thermostat and circulate water through the water passages.
Rotating propellers can cause serious injury or death. Never operate the boat
out of the water with a propeller installed. Before installing or removing a
propeller, place the drive unit in neutral and engage the lanyard stop switch
to prevent the engine from starting. Place a block of wood between the
propeller blade and the anti‑ventilation plate.
1. Remove the propeller. Refer to Propeller Replacement. Install the
flushing attachment so the rubber cups fit tightly over the cooling water
intake.
