Raymarine ECI-100 Universal Engine and Control Interface, NMEA 2000, IPX6

Overview

The Raymarine E70227 is a universal engine and control interface that links compatible engine data to a Raymarine SeaTalkng network so it can be shown on a compatible multifunction display. It uses a 12 V SeaTalkng connection and a 12 to 24 V engine CAN bus connection, with operating ranges of 10.8 to 16 V DC and 10.8 to 31.2 V DC respectively, in a housing that measures 109.2 x 30.2 x 21.35 mm.

On board, this unit sits between the engine network and the helm display so supported data such as RPM, engine hours, fuel flow, temperatures, pressures, battery voltage, trim, gear status, and alarms can be brought onto the screen. When paired with a Raymarine EV-2 autopilot and a compatible drive-by-wire steering system, it can also pass steering control data for supported installations.

Its environmental rating is IPX6 and IPX7, with 95% relative humidity tolerance and an operating range from -20°C to +55°C. That makes it a sensible fit for protected mounting spots around the helm, inside a console, or in other service spaces where spray, heat, and vibration are part of normal use.

Key features

• Bridges compatible engine CAN data onto a Raymarine SeaTalkng and NMEA 2000 network for display at the helm
• Displays data for up to two compatible engines when they share the same CAN bus
• Works with Volvo Penta EVC, Yamaha Command Link, Yamaha Command Link Plus, Yanmar, Honda, Caterpillar systems with MPD support, and other propulsion systems that use standard J1939 or NMEA 2000 protocols
• Adds drive-by-wire steering integration on supported systems when paired with a Raymarine EV-2 autopilot
• IPX6 and IPX7 waterproof rating with EN 60945 compliance for marine electronics use
• Small housing at 109.2 x 30.2 x 21.35 mm and 43 g for installs where space is limited
• Uses a 5 A breaker or fuse for a single-device power circuit

Compatibility and fit

This interface is a good match for boats already running Raymarine displays over SeaTalkng or NMEA 2000 and an engine package with compatible CAN data output. One unit can handle up to two compatible engines on a shared CAN bus. If each engine is on its own separate CAN network, one ECI-100 is needed for each network.

Engine-side connection hardware depends on the engine family and control system. Some installations need a Volvo EVC link cable, Yamaha Command Link Plus cable, DeviceNet cabling, or a J1939 tee and adapter layout. That matters during planning because the interface itself is only one part of the full engine-data path between the engine bus and the display backbone.

For owners who also want autopilot steering through the propulsion package, steering support is tied to the engine and control system in use. Supported drive-by-wire steering systems include Volvo Penta IPS, Volvo Penta Aquamatic joystick control, and Yamaha Helm Master when the network is built around a Raymarine EV-2 autopilot.

Installation and setup

The housing is light and easy to place behind a dash or inside a console, but the mounting spot still needs enough room for clean cable bends and access to the diagnostic LED. It should be mounted on a secure surface, kept close to the vessel's DC supply where possible, and placed about 1 m away from magnetic compasses when the boat layout allows it.

The supplied power cable includes a drain wire for RF grounding, and the DC system should be negative-grounded or floating. It should not be connected to a positive-ground system. On boats exposed to washdowns or regular spray, the enclosure rating helps, but connectors and service loops should still be routed in a way that keeps the installation tidy and protected.

This interface makes the most sense for skippers who want engine data on the same screen as charts and radar, or for boats moving toward integrated autopilot control on a compatible drive-by-wire package. It also suits repower jobs and helm refits where adding another standalone engine display is not the goal.
