CAUTION
Allow engine to cool down before disconnecting blue drain
hoses. Engine water temperature can exceed 160° F ( 71° C).
CAUTION
Ensure bilge pump is operating before beginning procedures.
Excess water in bilge can damage engine or cause boat to
sink.
1 Reconnect the UNCLOGGED blue drain hose to the bracket.
2 Ensure CLOGGED blue drain hose is in correct position below its
connection point to the block.
3 Turn on bilge pump.
4 Start engine. Allow it to run at idle until the obstruction is cleared
from the hose or for approximately 1 minute, whichever occurs first.
5 Check for water draining from the blue drain hose. If after 1 minute
of idling, the blue drain hose is still clogged, go to Step 6. If water is
draining, shut off engine and return to Step 3 of 3.0L Single Point
Drain.
