Check the shift link rod adjustment in forward shift position. The correct adjustment will position the shift cam far enough on the
roller in order to lock the reverse gate into forward position. The reverse gate should not be able to be forced up towards
neutral. Pull on the reverse gate by hand to verify.

Shift Cam Adjustment (Remote Control Models)

If not properly installed, the reverse gate can interfere with water coming off the rudder, suddenly and unexpectedly slowing
the boat. This can cause serious injury or death from occupants being thrown within or out of the boat. Adjust the shift cable
to prevent the reverse gate from interfering with water flow off the rudder.
1.
Attach the shift cable to the shift cam with a flat washer and a self‑locking nylon insert locknut, as shown. Tighten the
locknut against the flat washer, then back‑off the locknut 1/4 turn.
2.
Place the remote control handle into full forward position.
3.
Adjust the shift cable adjustment barrel so that the roller is at the full end of travel (bottom) in the shift cam.
4.
Attach the shift cable adjustment barrel to the bracket with a bolt and locknut. Tighten the bolt until it seats against the
adjustment barrel, then back‑off the bolt 1/4 turn. Hold the bolt from turning, and tighten the locknut on the bolt. The
adjustment barrel must be free to pivot.

5.
Recheck the shift cable adjustment in forward shift position. The correct shift adjustment will position the cam far enough
on the roller to lock the reverse gate into forward position. Push on the reverse gate by hand to verify it is locked into
position. The reverse gate should not move when pushed toward the neutral position.
IMPORTANT: The forward locking of the reverse gate must be met. If not, readjust the shift cable.
