Raymarine B45L Thru-Hull Depth Transducer, Bronze Housing, Fairing Block, 114 mm Stem, 22 mm Hole

Overview

The Raymarine E26019-PZ is a B45 bronze long-stem through-hull depth transducer with a fairing block for Raymarine instrument systems. It sends an analog depth signal to compatible Raymarine depth displays and instrument interfaces, making it a practical fit for boats that need a fixed hull-mounted depth sensor rather than a transom-mounted option.

The bronze stem-mount body is suited for fiberglass and wood hulls, and the included fairing block can be cut to match hull deadrise up to 26°. Installation requires a 22 mm (7/8 in) hull hole, with a 114 mm (4.5 in) stem length for this long-stem through-hull format.

With a 45 ft cable and 200 kHz depth operation, this transducer is well suited to cruising sailboats and powerboats where a clean underwater installation and dependable depth information matter for navigation, anchoring, fishing, and shallow-water awareness.

Key features

• Bronze through-hull, stem-mount body for fiberglass and wood hull installations.
• Included fairing block supports hull deadrise up to 26° and can be cut during installation for proper face alignment.
• 22 mm (7/8 in) hull hole requirement helps confirm fit before haul-out or yard work.
• 114 mm (4.5 in) long stem suits installations where extra stem length is needed through the hull and fairing.
• 45 ft cable gives practical routing length from the hull location to the instrument area.
• 200 kHz depth operation for Raymarine depth instrument use.
• Analog depth output for compatible Raymarine instrument systems and interfaces.

Compatibility and fit

This transducer is intended for Raymarine depth instrument installations that use an analog depth transducer input. It is commonly paired with Raymarine ST60+, ST290, i40 Depth, i50 Depth and iTC-5 based systems. ST70 installations require the matching ST70 Depth Pod, sold separately.

Fit should be checked against the vessel hull material, available inside-hull clearance, cable route and instrument interface before installation. Because this is a through-hull transducer, the installation location needs clean water flow, room for the fairing block and safe access inside the hull for securing and servicing the assembly.

Installation and setup

Plan the job as a hauled-out through-hull installation. The fairing block is used to help keep the transducer face aligned with the water flow, which is especially important on hulls with deadrise and on boats that run at different speeds or heel under sail.

Route the 45 ft cable away from sharp edges, high-heat areas and heavy electrical interference where possible. Final connection should match the Raymarine instrument or interface being used, especially on mixed older and newer instrument systems.

Materials and marine use

The bronze housing is a good match for underwater service on fiberglass and wood hulls, where the unit will be exposed to saltwater, vibration and normal hull movement. The fairing block also helps manage water flow across the transducer face, which supports cleaner depth readings on cruising boats, fishing boats and coastal powerboats.
