Troubleshooting Shift Problems

NOTE: The following information is provide to assist an installer in troubleshooting, if hard
shifting or chucking/racheting is encountered when shifting into forward gear.
1. When installing the control box in the side panel of the boat, ensure that the cables have
enough clearance to operate. This is necessary because the cables move up and down
when the shift handle is moved. If the control box is mounted too far back towards any
fiberglass structure, the cables will be interfered with, this will cause very hard shifting.
NOTE: The control box housing can be rotated in 30° increments to improve cable routing.
2. Ensure that when the shift cable from the control box is lead through the side gunnel of
the hull, that it does not have any extremely sharp bends in it as this will cause the stiff
shifting.
