Use a Mercury Precision or Quicksilver accessory (or equivalent) flushing
attachment.
To avoid possible injury when flushing, remove the propeller. Refer to
Propeller Replacement, following.
1. Remove propeller. Refer to Propeller Replacement. Install the flushing
attachment so the rubber cup fits 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 cup 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.
IMPORTANT: Do not run engine above idle when flushing.
4. Adjust water flow (if necessary) so excess water continues leaking out
from around the rubber cup to ensure the engine is receiving an
adequate supply of cooling water.
5. Check for a steady stream of water flowing out of the water pump
indicator hole. Continue flushing the outboard for 3 to 5 minutes,
carefully monitoring water supply at all times.
6. Stop the engine, turn off the water, and remove the flushing attachment.
Reinstall the propeller.
