2. INSTALLATION OF TRANSDUCERS
5. Attach the transducer to the hull.
Press the transducer firmly down on the hull
and gently twist it back and forth to remove
any air which may be trapped in the silicone
sealant.
6. Support the transducer with a piece of wood
to keep it in place while the sealant is drying.
It takes 24-72 hours to harden completely.
