Overview

The Raymarine E66066 is a transducer adapter cable that lets Raymarine A-Series fishfinders work with older hsb2 and DSM-series transducers. It adapts an 8-pin DSM-style transducer connection to a 7-pin sounder connection and carries depth, speed, and temperature data.

This is the part used when a boat already has a compatible DSM-family transducer in place and the owner wants to keep that transducer during an electronics upgrade. It is a practical option on refits where replacing an in-hull, thru-hull, or transom-mount transducer would add extra labor at the hull.

Key features

• Adapter cable for using hsb2 and DSM-series transducers with Raymarine A-Series fishfinders
• 8-pin DSM-style transducer connection to 7-pin sounder connection
• Supports depth, speed, and temperature functions when the connected transducer carries those outputs
• Works well in upgrades where an older display and separate DSM module are being removed but the existing transducer is staying in service
• Suitable for existing in-hull, thru-hull, and transom-mount transducer installations that use the matching DSM-style plug

Compatibility and fit

The main fit check for this cable is the transducer plug style and the display you are connecting it to. It is intended for boats with an older transducer that was previously used through Raymarine hsb2 or DSM sounder hardware, and it bridges that transducer to an A-Series fishfinder without changing the sensor at the hull.

It is a good match for owners updating a working fishfinder setup on a cruising or fishing boat where the transducer itself is still worth keeping. That matters most on installations with in-hull and thru-hull transducers, where replacement can be far more involved than swapping the display at the helm.

Installation and setup

Installation is straightforward at the electronics end of the system: the existing DSM-style transducer lead connects to the adapter, and the adapter then connects to the A-Series unit. When routing the cable, keep the connection supported and away from places where it can sit under strain or collect water behind the dash or inside the electronics compartment.

Before ordering, confirm that the transducer already on the boat is one of the older DSM-family types and that the display you are connecting has the matching A-Series sounder input. If your current setup uses depth, speed, and temperature, those functions depend on the transducer being wired and equipped for them in the first place.
