NOTE:
Adjust the cable joint at the jet pump end.
Refer to “REMOTE CONTROL CABLES AND
SPEED SENSOR LEAD” in Chapter 8. Adjustment steps:
Set the control grip to the neutral posi-
tion.
Loosen the locknut 1
.
Disconnect the cable joint 2
from the ball
joint 3
.
Turn the cable joint 2
in or out to adjust
the steering cable length c
.
Steering cable length
c:
218.8 mm (8.61 in)
NOTE:
Check that the sum of lengths c
and d
is
581.8 ±
1 mm (22.91 ±
0.04 in).
If the sum of lengths c
and d
is out of
specification, adjust length d
, and then
check the jet thrust nozzle distances
again.
WARNING
The cable joint must be screwed in more
than 8 mm (0.31 in).
Connect the cable joint and tighten the
