Locking Down The Transducer (Optional) - Humminbird HDR 610 Installation And Operation Manual

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