Step 2 (Fiberglass Boats) BRACKET INSTALLATION - If your boat has a stepped transom located below and under the main transom, the compact transducer design allows mounting in this area. This mounting location is recommended for good reading at very high speeds. (See Figure 5).
To install the metal bracket on a fiberglass boat, locate the template on the transom in the same manner as for an aluminum boat. (See figure 4). NOTE: On boats with more than 15° deadrise angle it may be necessary to mount the transducer slightly off parallel with the water level. (See Figure 6).
Mark and drill the three 9/6," dia holes as shown on the template. Attach the metal bracket using the three #10 self threading screws supplied. Be sure to align the holes so that they are centered vertically in the three slots found in the bracket. It is important to use a silicone sealant between the screwhead and bracket in order to prevent leaking.
