7. Locking Down the Transducer (Optional)

NOTE: You have the option to lock down the Two Piece Kick Up bracket if you do not want the transducer to kick up. Please be aware, however, that the transducer can be damaged if it is locked down and it strikes debris in the water.

Locking the Pivot Arm

1.To lock down the transducer, trace the position of the mounting bracket. Force the pivot to the Up position to gain access to the mounting screws, then re-align the mounting bracket against the transom of the boat to match the traced silhouette. Check the bracket position with the level again to make sure it is still level, then mark the fourth mounting hole using a pencil or marker (see the illustration Using the Mounting Bracket to Mark the Initial Drill Holes). Unscrew and remove the mounting screws and the transducer assembly and set aside.

2.Drill the fourth mounting hole, using a 9/64" drill bit. Use a marine gradesilicone sealantto fill all four drilled mounting holes, especially if the holes penetrate the transom wall.

3.Re-position the transducer assembly against the transom of the boat, then hand install the first three screws (two on the outside edges and one in the 3rd mounting hole). Make sure that the transducer location and the pivot angle have not changed, then fully tighten all three mounting screws (see the illustration

Fully Tighten All Three Mounting Screws). Hand-tighten only! Snap the pivot back down.

4.Install #8 x 1" wood screw into the 4th hole to lock down the pivot arm (see the illustration Locking the Pivot Arm). Hand-tightenonly!
