8-7 POWER TRIM AND TILT
Inspect the PTT cap seal and O-ring.
Replace if cuts, nicks, or excessive wear is found.
NOTE:
It is recommended that the O-ring always be replaced once the
tilt cylinder has been disassembled.
Inspect the shock valves (spring, rod and ball).
Replace if there are any signs of rust or pitting.
Inspect the cylinder bore for evidence of a rough or grooved
surface.
Light honing may rectify slight surface roughness or scarring,
but a deeply scarred surface will require replacement of the tilt
cylinder.
Inspect all O-ring (manual release valve and main check valve).
Replace if nicked or cut.
