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 at least every three years or 300 operating hours. System capacity is approximately 15.2 fl. oz. (450 ml).
IMPORTANT: Use only Evinrude/Johnson Bio degradable TNT Fluid to fill the hydraulic system. Refer to Trim and Tilt on p. 66 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).
ELECTRICAL CIRCUIT TESTS
Relay Testing
When the trim-UP button is pressed, the UP relay is energized and connects the blue trim motor wire to the battery positive (+) terminal. The green trim motor wire remains grounded. When the button is released, the blue trim motor wire returns to a grounded position.
When the trim-DOWN button is pressed, the DOWN relay is energized and connects the green trim motor wire to the battery positive (+) terminal. The blue motor wire remains grounded. When the button is released, the green trim motor wire returns to a grounded position.
Refer to TILT/TRIM RELAY TEST on p. 130 for relay testing procedure.
Trim and Tilt Motor Current Draw Tests
Careful analysis of the electric motor's current draw and trim/tilt unit operating speed aids evaluation of the electric motor and certain mechanical components.
Use a battery rated at 360 CCA (50 Ah) or higher that is in good condition and fully charged to per form this test.
IMPORTANT: Specifications are for static hydraulic tests. DO NOT attempt to perform the following tests while the boat is moving.
