1. INSTALLATION
1-12
Installing the transom mount transducer projecting from hull (for deep-V hulls)
This method is employed on deep-V hulls and provides good performance because 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 “saturation” will be lengthened and
performance will be reduced.
Do not paint the transducer. Performance will be affected.
Triducer
525ST-MSD
The triducer is designed for thru-hull mounting.
Mounting considerations
When selecting a mounting location keep the following points in mind:
•
Air bubbles and turbulence caused by movement of the boat seriously degrade the
sounding capability of the transducer. The transducer should, therefore, be located in a
position where water flow is the smoothest. Noise from the propellers also adversely
affects performance and the transducer should not be mounted nearby. The lifting strakes
are notorious for creating acoustic noise, and these must be avoided by keeping the
transducer inboard of them.
•
The transducer must always remain submerged, even when the boat is rolling, pitching or
up on a plane at high speed.
•
A practical choice would be somewhere between 1/3 and 1/2 of the boat’s length from the
stern. For planning hulls, a practical location is generally rather far astern, so that the
transducer is always in water regardless of the planning attitude.
