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.
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 propeller. Refer to Propeller Replacement. Install the flushing
attachment so the rubber cups fit tightly over the cooling water intake.
2. Attach a water hose to the flushing attachment. Turn on the water and
adjust the flow so water is leaking around the rubber cups to ensure the
engine receives an adequate supply of cooling water.
3. Start the engine and run it at idle speed in neutral shift position.
