5.Replace the O-ring and Backup O-ring on the transducer holder. It is highly recommended that the O-rings be replaced when the transducer is removed from the holder or stalk. Make sure that the contoured side of the ring is facing away from the mount. Lubricate with Molykote111 Silicone Grease or equivalent.

Note: Replacing the O-rings at this point minimizes the chances of damaging the transducer by dropping it.

6.Apply a small amount of nickel anti-seize (N.A.S.) compound (P/N 2-9-9960-134) to the outer threads of the transducer holder (see Figure 7-6).

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 7-8).

8.If applicable, install the mount cover by rotating the tag and sliding the mount cover over the 1 1/4” hex head of the transducer holder. Align the mount’s two screws with their respective screw holes and tighten. The screw holes can be located as they are marked with an arrowhead, “V” on the mount rim.
