4. Permanently Mounting the Transducer
1. Make sure the position of the transducer is marked.
2. You may have to disconnect the cable to the control head and reconnect it at the end
of this procedure.
3. Remove the water from inside the hull and thoroughly dry the mounting surface. If the
surface is excessively rough, it may be necessary to sand the area to create a smooth
mounting surface.
4. Slowly and thoroughly mix an ample quantity of two-part slow cure epoxy. Avoid
trapping air bubbles.
5. Coat the face of the transducer and the inside of the hull with epoxy.
6. Press the transducer into place with a slight twisting motion to purge any trapped air
from underneath, keeping the end of the transducer that has the mounting knuckle
pointed forward, towards the bow of the boat.
NOTE: Proper operation requires the end of the transducer that has the mounting knuckle to face
towards the bow of the boat.
7. Weight the transducer so that it will not move while the epoxy is curing.
NOTE: When the epoxy cures, no water is necessary inside the hull.
8. If you unplugged the transducer cable at the beginning of this procedure, plug it back
into the control head.
NOTE: Neither water, spilled gasoline, nor oil will affect the performance of the transducer.
