INSTALLATION

TRANSOM INSTALLATION

∙If the propeller(s) is (are) forward of the transom, it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered.

Step Two - Drill the Mounting Holes

1.Remove the mounting template from the front of the Operations Manual.

2.Hold the template on the transom of the boat in the location where the transducer will be installed (Figure 4). Align the template vertically, ensuring the lower edge of the transom meets with the bottom corner of the template.

3.Using a pencil or punch, mark the two mounting holes shown on the template onto the transom. Do not mark or drill any other holes at this time.

4.Using a 5/32” (4mm) bit drill the two holes to a depth of approximately 1" (3cm). On fiberglass hulls, it is best to start with a smaller bit and use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.

Step Three - Assemble the Transducer

1.Attach the Pivot to the transducer body as shown in Figure 5, using the #8 – 3/8” (9mm) long allen headed pivot screw, the headed pin, the two flat washers, and the two toothed lock washers.

Note: The toothed lock washers must be positioned between the transducer and the pivot ears. The flat washers must be positioned to the outside at the pivot ears.

2.Using the AIlen wrenches provided, loosely tighten the pivot screw (Figure 6). Do not completely tighten the assembly at this time, so the pivot angle can be adjusted later.

3.Insert the pivot/transducer assembly into the mounting bracket as shown in Figure 7. Do not snap the assembly closed.
