ROUTINE INSPECTIONS
ROUTINE INSPECTIONS
General
Check for exte rnal signs of fluid leakage. Correct
causes as necessary.
Check the b attery and make sure it is in go od
operating condition.
Reservoir Fluid
Check reservo ir fluid level every th ree yea rs or
every 300 opera ting ho urs. System cap acity is
approximately 21 fl. oz. (620 ml).
Refer to Trim and T ilt on p. 39 for filling proce-
dure.
Manual Release Valve
Check the manual release valve with a torq ue
wrench.
IMPORTANT: Tighten valve to a torque of 45 to
55 in. lbs. (5 to 6 N·m).
Stern Brackets
Inspect the stern brackets for binding.
Tighten starboard tilt tube nut 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 h as not been d etermined, th e Symp-
toms Chart on p. 341 should help locate the
problem.
Keep a manual release valve and a valve body in
stock for troublesho oting. Use these p arts whe n
the Service Proce dures on p. 341 call fo r t he
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. 105.
If the outboard tilts part way up but not smoothly,
or with a const ant sound, there is probably air in
the s ystem du e t o l ow fluid. Fi ll re servoir an d
bleed (purge air from) the system.
To test fo r mechanical binding, op en the manua l
release valve and manually tilt the motor up and
down. If parts are binding, refer to MIDSECTION
section.
If the outboard will not st ay in shallow water drive
and drops down at fast idle, the wrong manual
release valve may be inst alled. Check f or th e
identification groove in the face of the valve.
