Transducer 525-5Pwd (Transom Mount) - Furuno BBDS1 Operator's Manual

The fairing block should be smaller than the transducer itself to provide a channel to divert
turbulent water around the sides of the transducer rather than over its face.

2. Drill a hole just large enough to pass the threaded stuffing tube of the transducer through the
hull, making sure it is drilled vertically.
3. Apply a sufficient amount of high quality caulking compound to the top surface of the trans-
ducer, around the threads of the stuffing tube and inside the mounting hole (and fairing blocks
if used) to ensure watertight mounting.
4. Mount the transducer and fairing blocks and tighten the locking nuts. Be sure that the trans-
ducer is properly oriented and its working face is parallel to the water line.

Note: Do not over-stress the stuffing tube and locking nuts through excessive tightening, since
the wood block will swell when the boat is placed in the water. It is suggested that the nut be tight-
ened lightly at installation and retightened several days after the boat has been launched.

Transducer 525-5PWD (transom mount)

This type of mounting is very commonly employed for outboard motor boats. Do not use this meth-
od on an inboard motor boat because turbulence is created by the propeller ahead of the trans-
ducer.
There are two methods of installation: flush with hull (for flat hulls) and projecting from hull (for
deep V-hulls).
