Installing the transom mount transducer
This type of mounting is very commonly employed, usually on rela-
tively 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).

Figure 1-16 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 (sup-
plied).
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 experi-
mentation for fine tuning at high cruising speeds.
4. Fill the gap between the wedge front of the transducer and tran-
som with epoxy material to eliminate any air spaces.
