7. Carefully install the transducer holder assembly into the transducer mount. Make
sure the threads of the holder and mount are correctly aligned. Use a 1 1/4” socket
and screw the transducer assembly into the mount. Tighten to securely seat the
assembly in the mount. Do not over tighten (see Figure 3-3).
