Figure 1-17 Transom mount transducer, mounting flush with hull
Installing the transom mount transducer projecting from hull
(for deep-V hulls)
This method is employed on deep-V hulls and provides good performance be-
cause the effects of air bubbles are minimal. Install the transducer parallel with
water surface; not flush with hull. If the boat is placed on a trailer care must be
taken not to damage the transducer when the boat is hauled out of the water and
put on the trailer.

Transducer preparation
Before putting the boat in water, wipe the face of the transducer thoroughly with a
detergent liquid soap. This will lessen the time necessary for the transducer to
have good contact with the water. Otherwise the time required for complete "satu-
ration" will be lengthened and performance will be reduced.
Do not paint the transducer. Performance will be affected.
