NOTE: Your transducer may not look exactly like the transducer shown in the illustrations, but it will mount in exactly the same way. 531390-1_C 2 Side Imaging Transducer · On boats with stepped hulls, it may be possible to mount the transducer on the step. Do not mount the transducer on the transom behind a step to avoid popping the transducer out of the water at higher speeds; the transducer must remain in the water for the control head to maintain the sonar signal. [. . . ] If this is not possible, select a location on the transom where the hull forward of this location is smooth, flat and free of protrusions or ribs. Step 2. Mounting the Bracket In this procedure you will mount the bracket, using the mounting template provided as a guide. This template allows you to mark where the mounting holes should be drilled. Hold the template on the transom of the boat in the location you have selected. Align the template vertically, matching the lower edge of the transom with the bottom corner of the template. Rib 2a. If you are routing the cable over the transom of the boat, secure the cable by attaching the cable clamp to the transom, drilling 9/64" diameter holes for #8 x 5/8" wood screw(s), go directly to procedure 7, Connecting the Cable. Running Position Adjustment The running position of the transducer is now completely adjustable. Subsequent adjustment may be necessary to tweak the installation after high speed testing. The mounting bracket allows height and tilt adjustment; the pivot screws allow angle adjustment. NOTE: Side imaging is best performed at boat speeds from 2 to 6 mph. If the boat is stationary, the same information is displayed over and over. If the boat is moving too quickly, there will be gaps between the strips of information. Slower speeds are good for longer ranges, while faster speeds can be used at shorter ranges. Screw Stainless Washer (fits over screw threads) 2b. If you will be routing the cable through a hole in the transom, drill a 5/8" diameter hole above the waterline. Route the cable through this hole, then fill the hole with marine-grade silicone sealant and proceed to the next step immediately. Place the escutcheon plate over the cable hole and use it as a guide to mark the two escutcheon plate mounting holes. Remove the plate, drill two 9/64" diameter x 5/8" deep holes, and then fill both holes with marine-grade silicone sealant. Place the escutcheon plate over the cable hole and attach with two #8 x 5/8" wood screws. This will be required for in-warranty service. 531390-1_C 7 Side Imaging Transducer Humminbird® Service Policy Even though you'll probably never need to take advantage of our incredible service policy, it's good to know that we back our products this confidently.
