1. INSTALLATION

Installing the transom mount transducer
This type of mounting is very commonly employed, usually on reactively small I/O or
outboard boats. Do not use this method on an inboard motor boat because turbulence is
created by the propeller ahead of the transducer.
There are two methods of installation: flush with hull (for flat hulls) and projecting from hull
(for deep V-hulls).

Transom mount transducer mounting locations
Installing the transom mount transducer flush with hull (for flat hulls)
A suitable mounting location is at least 50 cm away from the engine and where the water
flow is smooth.
1. Drill four pilot holes in the mounting location.
2. Attach the transducer to the bracket with tapping screws (supplied).
3. Adjust the transducer position so the transducer faces right to the seabed.
Note: If necessary, to improve water flow and minimize air bubbles staying on the
transducer face, incline the transducer about 5° at the rear. This may require a
certain amount of experimentation for fine tuning at high cruising speeds.
4. Fill the gap between the wedge front of the transducer and transom with epoxy material
to eliminate any air spaces.
