Raymarine E66054 P66 Transom Mount Triducer

The Raymarine E66054 P66 Transom Mount Triducer is a purpose-built fishfinder transducer designed for anglers who demand accurate sonar performance without the complexity of through-hull installation. This transom-mount unit delivers real-time water column imaging and bottom definition to a range of Raymarine Echo Sounders, making it ideal for recreational boaters, tournament anglers, and anyone running moderate-beam vessels who wants to quickly locate structure, thermoclines, and active fish. The compact, rugged design mounts directly to your transom, eliminating the need for haul-outs or expensive marine fabrication work.

Built on Raymarine's proven triducer technology, the P66 combines multiple frequency channels in a single housing to deliver high-definition sonar imagery across shallow flats and deep offshore water. The transducer integrates with Raymarine's digital sonar platform, processing raw acoustic data into crisp, real-time target separation and bottom hardness discrimination. Its stainless steel and composite construction withstands saltwater corrosion and impact from docks, rocks, and debris—a critical advantage on hard-fished waters where gear gets punished. At just 2 pounds, the compact profile minimizes drag and hydrodynamic interference, preserving fuel efficiency and handling characteristics on plane.

The Raymarine E66054 P66 Transom Mount Triducer is fully compatible with the SL Series (SL755RC, SL760RC, SL1250, SL1250RC), HSB2 Plus Series (L755RC, L760, L760RC, L1250, L1250RC), and HSB2 HDFI Series (DSM250, L770D, L770DRC, L1260D, L1260DRC) Echo Sounders, covering most modern Raymarine fishfinder platforms. Installation requires only a stainless steel bracket, coaxial cable connection, and transom mounting bolts—typically a 30-minute job requiring no specialized tools. For boaters upgrading legacy systems or adding side-imaging capability to an existing display, this transducer provides proven performance and Raymarine's extended warranty support.
