1.4 Transducer 525-5PWD (transom mount)
This type of mounting is very commonly employed for outboard motor boats. Do not
use this method on an inboard motor boat because turbulence is created by the pro-
peller ahead of the transducer.
There are two methods of installation: flush with hull (for flat hulls) and projecting from
hull (for deep V-hulls).

1.4.1 Installation 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 self-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.
