Installation procedure
1. Lightly roughen the transducer face with #100 sandpaper. Also, use the sandpa-
per to roughen the inside of the hull where the transducer is to be mounted. Wipe
off any sandpaper dust from the face of the transducer.
2. Dry the face of the transducer and the hull. Coat the transducer face and mounting
location with marine sealant. Hardening begins in approx. 15 to 20 minutes so do
this step without delay.
Transducer
3. 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 marine
sealant.
4. Support the transducer with a piece of wood to keep it in place while the sealant
is drying. It takes 24 to 72 hours to harden completely.
