ROUTINE INSPECTIONS
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. 81 for filling procedure.
Manual Release Valve
Check the manual release valve with a torque 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 has not been determined, the Symptoms Chart on p. 339 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. 339 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. 144.
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.
