TO PURGE:
IMPORTANT: Fill plug and O-ring must be tightened securely before purging sys-
tem.
IMPORTANT: Run Trim System in short "jogs" until pump is primed and trim sys-
tem moves. If trim motor is run without priming pump, driveshaft failure could re-
sult.
Cycle outboard through entire trim/tilt range 4 times. Check fluid level after purging sys-
tem.
Push down on outboard when trim rams are slightly extended. If rams retract more than
1/8 in. (3.2 mm), air is present in system. Cycle system again and check fluid level.
