mounting surface of hull and transducer with rubbing alcohol.
c) Get a quantity of epoxy and hardener, mix them in a certain proportion and thoroughly,
slowly stir them on a paper plate. Avoid forming air bubbles in the epoxy.
d) When the epoxy looks unworkable (about 20 minutes are needed from the beginning
you mixing them), make sure there are no air bubbles in the epoxy layer, then spread a
thin layer of epoxy on the surface of transducer, a comparably thick layer to the surface
of sand area on the hull.
e) Press the transducer into the epoxy of the sanding area on the hull with a slight twisting
motion, forcing any air bubbles out from underneath. Make sure the face of the
transducer will be parallel with the hull after you finish all the above job.
Warning: do not bump the transducer while the epoxy is wet. It will take about 24hous
for the epoxy curing completely.
Note: weight the transducer with some heavy object to prevent it from moving during
the epoxy curing,
When the epoxy cures completely, drain out the remained water from the hull.
f) Route the cable to the control head, and now it’s ready to use.
