3-2 E INSP ADJ CONTROL SYSTEM PERIODIC SERVICE CONTROL SYSTEM Steering master inspection 1. Inspect: Steering master Excessive play → Replace the steering master. Refer to “STEERING MASTER” in Chapter 8. Inspection steps: Move the handlebar up and down and back and forth. Check the excessive play of the handle- bar. Steering cable inspection and adjustment 1. Inspect: Jet thrust nozzle clearance a , b Difference → Adjust. 2. Adjust: Steering cable joint (steering master end) Inspection steps: Set the control grip in the neutral position. Turn the handlebar from lock to lock. Measure clearances a and b . If clearances a and b are not the same, adjust them. Adjustment steps: Set the control grip in the neutral position. Loosen the locknut 1 . Disconnect the steering cable joint 2 from the ball joint 3 . Turn the cable joint in or out for adjusting the clearance. Turn in Clearance a is increased. Turn out Clearance b is increased.
3-3 E INSP ADJ CONTROL SYSTEM NOTE: If the steering cable cannot be properly adjusted by the cable joint at the steering mas- ter end, adjust the cable joint at the jet pump end so that the same clearances are obtained. Refer to “REMOTE CONTROL CABLES AND SPEED SENSOR LEAD” in Chapter 8. WARNING The cable joint must be screwed in more than 8 mm (0.31 in). Connect the cable joint and tighten the locknut. T R.. Locknut: 6.4 N m (0.64 kgf m, 4.6 ft lb) Throttle cable inspection and adjustment NOTE: Before adjusting the throttle lever free play, adjust the trolling speed. 1. Measure: Throttle lever free play a Out of specification → Adjust. Throttle lever free play: 4–7 mm (0.16–0.28 in)
