6. Adjust shift cable as follows:
a. Position the control box into forward position.
b. Position the reverse gate against the forward stop. With the reverse gate at this
position, adjust the cable barrel to fit into the barrel holder with slight tension of the
reverse gate against the stop.
c. After adjusting the shift cable, secure the cable barrel in place with the shift cable
retainer. Fasten the retainer by tightening both locknuts.
IMPORTANT: The shift cable retainer must be fastened with self-locking nylon insert
locknuts. These locknuts must never be replaced with common nuts (non-locking)
as they could vibrate off, freeing the shift cable to disengage.
WARNING
Disengagement of the shift cable can result in the boat suddenly shifting into
reverse. This unexpected action could cause occupants to be thrown forward in the
boat or to be ejected overboard. Serious injury or death could result.

7. Adjust the reverse stop (located on starboard side of the nozzle) so that the stop just
touches the reverse gate with the control handle in reverse position. Torque reverse stop
screw to 14 Nm (120 lb in.).
8. Check shift cable/reverse gate adjustment as follows:
a. Shift the control box a few times from the forward position to reverse position.
b. Return the control handle back to forward. Pull back on the reverse gate gently to
take slack out of the cable. Check for the 9.5 to 12.7 mm (3/8 to 1/2 in.) clearance
space between the reverse gate and rudder. If necessary, readjust the cable barrel.
