You are now ready to install the transducer. Find the section that refers to your specific transducer installation method.

Transducer Installation Overview

Proceed to the installation section that matches your transducer type. Your choices are as follows:

•858c, 958c: DualBeam PLUS™ (XNT 9 20 T), Transom Mount

•858c, 958c: DualBeam PLUS™ (XNT 9 20 T), Inside the Hull Mount

•898c SI, 998c SI: Side Imaging® (XHS 9 HDSI 180T), Transom Mount

•All units: Trolling Motor Transducer Installation

NOTE: Due to the wide variety of hulls, only general instructions are presented in this installation guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. It is important to read the instructions completely and understand the mounting guidelines before beginning installation.

NOTE: If the included transducer will not work for your application, you may exchange it, NEW and UNASSEMBLED, with mounting hardware included, for a transducer appropriate for your application - often at very little or no charge depending on the transducer.
