Hydraulic System Troubleshooting
Support outboard with tilt lock lever when servicing
power trim system.
IMPORTANT: After debris or failed components
have been found (during troubleshooting proce-
dure) it is recommended that unit be disas-
sembled completely and ALL O-rings be re-
placed. Check ball valve components and
castings must be cleaned using engine cleaner
and compressed air or replaced prior to reas-
sembly.
IMPORTANT: Power trim system is pressurized.
Outboard must be in the full “UP” position (cylin-
der fully extended) prior to fill screw or manual
release valve removal.
Refer to instructions following if disassembly is re-
quired.
Follow preliminary checks before proceeding to trou-
bleshooting flow diagrams (following).
Preliminary Checks
IMPORTANT: Operate Power Trim system after
each check to see if problem has been corrected.
If problem has not been corrected proceed to
next check.
1. Check that manual release valve is tightened to
full right (clockwise) position.
2. Check trim pump fluid level with outboard in full
“UP” position and fill if necessary. Refer to “Fill
and Purge the Power Trim System”.
3. Check for external leaks in Power Trim system.
Replace defective part(s) if leak is found.
4. Outboard not holding tilted position (falls to trim
in position) indicates debris or defective compo-
nents in trim valve assembly. Clean or replace
components as required.
5. Check manual release valve for broken stem and
one O-ring remaining in the release valve pas-
sage. (Separate the manifold assembly from the
cylinder to dislodge broken stem.) Install new re-
lease valve and test system.
6. Check for nicked, deteriorated or misplaced O-
rings throughout trim system.
Leak Down Check – Pump and
Manifold Assembly
NOTE: Scribe (d) pump housing halves before disas-
sembly.
1. Debris or chips between valve and seat (a). Usu-
ally imbedded in rubber valve seat.
2. Nicked or deteriorated O-ring (b).
3. Nicked, deteriorated or misplaced O-ring be-
tween manifold and trim cylinder. Refer to “Man-
ifold Removal” for O-ring location.

4. After reassembly, insert driveshaft and check
pump rotation resistance to turning – housing
halves can shift/turn during reassembly. Align
scribe marks (d) carefully.
