4. Partially open the water source to about 1/2 maximum. Do not use full water pressure.
CAUTION
Engine overheating can cause engine damage. To avoid, observe the water
temperature gauge and ensure the engine is operating in the normal ranges.
5. Place the remote control in NEUTRAL, IDLE speed position and start the engine.
CAUTION
Suction created by seawater pickup pump may collapse the flushing hose, causing
the engine to overheat. Do not run engine above 1500 rpm when flushing.
6. Operate the engine at idle speed, in NEUTRAL, for about 10 minutes, or until discharge
water is clear.
7. Stop the engine.
8. Shut off the water tap.
9. Remove the adapter from the seawater pump inlet hose connection and reconnect the
seawater inlet hose. Tighten the hose clamps securely.
CAUTION
If boat is in the water, the seacock must remain closed until engine is to be re-started
to prevent water from flowing back into cooling system. If the boat is not fitted with
a seacock, the water inlet hose must remain disconnected and plugged to prevent
water from flowing back into cooling system, boat, or both. As a precautionary
measure, attach a tag to the ignition switch or steering wheel of the boat with the
warning: Open seacock or reconnect water inlet hose before starting engine.
