Installing the Transducer Bracket. Repeat for the second hole.
5. Use a 1/2" (13 mm) wrench to tighten the assembly, but do not fully tighten the hardware at
this time (so you can make adjustments if needed after testing the installation).

| Confirm the Mounting Angle
You will need to adjust the initial angle of the transducer both vertically and horizontally to confirm
the transducer mounting angle.
1. Confirm the height of the transducer is high enough on the transom so it is out of the jet stream
when the boat is on plane and that it will be submerged in the water during trolling speeds.
To adjust the height, loosen the screws slightly in the transom bracket, and slide the bracket
up or down using the slots. If you cannot access the screws, you may need to uninstall the
transducer, adjust the height, and repeat the installation instructions in sections 1 and 2.
2. Adjust the angle of the transducer, so it is parallel with the length of the boat hull, with a slight
down angle (approximately 5 degrees).
3. Hand tighten the two pivot bolts, using a 1/2" (13 mm) wrench.
NOTE: You will finalize the installation after you route the cable and test the installation in
the following procedures.

| Route the Cable
You can route the cable over the transom or through a hole in the transom above the waterline.
Your boat may have a pre-existing wiring channel or conduit that you can use to route the cable.
Select the routing method that is best for your boat configuration, and purchase any extension
cables, cable clips, clamps, etc. as needed.
Δ It is best to route the cable to the side of the transducer so the transducer will not damage
the cable during movement.
