Raymarine RV-100 RealVision 3D Transom Bracket Kit, Stainless Steel

Overview

The Raymarine R70521 is a transom bracket kit for the RV-100 RealVision 3D transducer, used when replacing damaged mounting hardware or setting up an RV-100 transom installation with the correct bracket components. It is made for the RV-100 transducer and includes the stainless steel transom bracket, mounting screws, kick-up pivot hardware, transducer carrier bracket, and carrier mounting bolt.

This kit helps keep the transducer in the proper position on the stern so sonar returns stay consistent while the boat is running, fishing, or moving through changing water conditions. The kick-up pivot hardware is useful on transom-mounted installations because it helps the assembly move if it contacts floating debris, a stump, or another underwater obstruction.

The RV-100 transducer and cable are not included, so this kit is best used when the transducer itself is still serviceable and only the mounting hardware needs to be replaced or renewed.

Key features

• Direct fit for Raymarine RV-100 RealVision 3D transom-mount transducers.
• Includes the stainless steel transom bracket used to secure the transducer at the stern.
• Kick-up pivot hardware helps protect the transducer assembly during an impact with debris or bottom structure.
• Useful as a replacement or service kit when original RV-100 mounting hardware is missing, worn, or damaged.
• Supports proper transducer alignment for dependable sonar operation on outboard-powered boats and similar transom-mount applications.
• RV-100 transducer and cable are not included.

Installation and setup

Install the bracket on a clean, solid section of the transom where the RV-100 can remain in clean water flow while the boat is underway. Placement matters because turbulence, aerated water, or interference from strakes, steps, trim tabs, or prop wash can affect sonar performance.

Before drilling, confirm the transducer location, check clearance for trailer bunks and swim platforms, and make sure the bracket can pivot without obstruction. Seal fastener holes with an appropriate marine sealant during installation to help protect the transom core from water intrusion.

Compatibility and fit

This kit is intended for the Raymarine RV-100 RealVision 3D transducer. It does not convert other transducers to RV-100 mounting and should not be treated as a universal transducer bracket. It is a practical match for boat owners who need to restore the original transom mounting arrangement without replacing the full transducer and cable assembly.
