Transom Mount Transducer; Inside-Hull Transducer - Furuno FCV-585 Operator's Manual

4.3 Transom Mount
Transducer
The transom mount transducer is very com-
monly employed, usually on relatively 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 trans-
ducer.
DO NOT overtighten screws. They may be
damaged.

Choose the installation method depending on
the rise angle of the hull.

525-5PWD mounting locations
Installing the 525-5PWD
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 for self-tapping screw
(5x20) in the mounting location.
2. Attach the transducer to the mounting loca-
tion with self-tapping screws.
3. Adjust the transducer position so the trans-
ducer faces right to the bottom.
If necessary, to improve water flow and
minimize air bubbles staying on the trans-
ducer 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 mate-
rial to eliminate any air spaces.
