Flushing the Cooling System (Continued) - Using
Gear Case Flushing Attachments
To avoid possible injury when flushing, remove the propeller.
Refer to Propeller Replacement.
1
Remove propeller (refer to Propeller Replacement). Install the
flushing attachment to 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 flushing
attachment 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.
4
Adjust water flow so excess water continues leaking out from
around the flushing attachment 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 hoses. Continue flushing the outboard for 3 to 5 min-
utes, carefully monitoring water supply at all times.
6
Stop the engine, turn off the water, and remove the flushing at-
tachment. Reinstall the propeller.
