Transom Mount Transducer - Furuno GP-1670F Installation Manual

5. Mount the transducer and fairing blocks and tighten the locknut. Be sure that the
transducer is properly oriented and its working face is parallel to the waterline.
Hull
Note: Do not over-stress the stuffing tube and locknut through excessive tightening,
since the wood block will swell when the boat is placed in the water. It is suggested
that the nut be tightened lightly at installation and retightened several days after the
boat has been launched.
Transducer preparation
Before putting the boat in water, wipe the face of the transducer thoroughly with a de-
tergent liquid soap. This will lessen the time necessary for the transducer to have good
contact with the water. Otherwise the time required for complete "saturation" will be
lengthened and performance will be reduced.
DO NOT paint the transducer. Performance will be affected.

Transom Mount Transducer

The optional transom mount transducer 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.
DO NOT overtighten screws; they may be damaged.
