Raymarine Step Mount, For RV-100 RealVision 3D Transom Mount Transducer

Overview

The Raymarine A80479 is a stainless steel hull and step mount bracket for fitting an RV-100 RealVision 3D transom mount transducer to a stepped hull. It gives the transducer a proper mounting point where a standard transom position is not the right fit, which matters on boats where hull steps, strakes, prop wash, or aerated water can interfere with sonar readings.

This bracket is made for the RV-100 RealVision 3D transducer and is used when the transducer needs to be mounted on a horizontal surface at the step of the boat. The package is listed at 2 in H x 8 in W x 12 in L with a weight of about 1.4 lb, so it is a small but important installation accessory rather than a replacement transducer.

Key features

• Fits the Raymarine RV-100 RealVision 3D transom mount transducer for stepped hull installations.
• Stainless steel bracket construction suits exposed transducer mounting areas below or near the hull step.
• Supports mounting on a horizontal surface, which helps keep the transducer face in the correct operating position.
• Allows cable routing with the cable exiting toward the bow or toward the stern, depending on hull layout and installation clearance.
• Useful for boats where a conventional transom mount location may place the transducer in turbulence, aeration, or propeller wake.

Installation and setup

Mounting location is the key detail with this part. The RV-100 transducer should sit where water flow is as clean as possible, with enough distance from propellers, ribs, rivets, strakes, and other hull features that create turbulence aft of their position. On stepped hulls, leaving enough clearance for the cable is also important, especially when the cable exits toward the bow.

The bracket is attached to the RV-100 transducer after the standard transducer hanger is removed. Once the transducer and bracket are held in place, the mounting surface can be marked through the bracket holes before fastening. Careful alignment at this stage helps the sonar beam work from the correct angle instead of fighting the hull shape.

Compatibility and fit

This mount is for the Raymarine RV-100 RealVision 3D transom mount transducer. It is not a universal transducer bracket, and it should be matched to the RV-100 installation style and hull form before drilling. It is a practical fit for boats with stepped transoms or stepped running surfaces where the transducer needs a different mounting point than the standard transom bracket allows.

Use cases on board

This bracket makes sense for owners adding or refitting an RV-100 transducer on bass boats, flats boats, skiffs, and other planing hulls where bottom shape and water flow can complicate sonar placement. It is especially relevant when clean water contact below the hull step is more important than keeping the transducer on the vertical transom face.
