TRIM AND TILT
ROUTINE INSPECTIONS
ROUTINE INSPECTIONS
General
Check for external signs of fluid leakage. Correct
causes as necessary.
Check the battery and make sure it is in good
operating condition.
Reservoir Fluid
Check reservoir fluid level every three years or
every 300 operating hours. System capacity is
approximately 21 fl. oz. (620 ml).
Refer to
Trim and Tilt
on p. 79 for filling proce-
dure.
Manual Release Valve
Check the manual release valve with a torque
wrench.
IMPORTANT:
The valve must be tightened to a
torque of 45 to 55 in. lbs. (5 to 6 N·m).
Stern Brackets
Inspect the stern brackets for binding with the
swivel bracket in the thrust rod area. Retorque the
tilt tube nuts as follows:
•
Tighten the tilt tube nuts to a torque of 45 to 50
ft. lbs. (61 to 68 N·m).
TROUBLESHOOTING
If the power trim/tilt system has malfunctioned and
the cause has not been determined, the
Symp-
toms Chart
on p. 323 should help locate the
problem.
Keep a manual release valve and a valve body in
stock for troubleshooting. Use these parts when
the
Service Procedures
on p. 323 call for the
substitution of known good parts.
If the trim/tilt does not work, and its motor neither
runs nor hums, troubleshoot the problem by refer-
ring to
TILT/TRIM RELAY TEST
on p. 141.
If the outboard tilts part way up but not smoothly,
or with a constant sound, there is probably air in
the system due to low fluid. Fill reservoir and
bleed (purge air from) the system.
To test for mechanical binding, open the manual
release valve and manually tilt the motor up and
down. If parts are binding, refer to
MIDSECTION
section.
If the outboard will not stay in shallow water drive
and drops down at fast idle, the wrong manual
release valve may be installed. Check for the
identification groove in the face of the valve.
