I have an axiom pro 16, Evolution pilot, cp470, Ray73 and ECI-100 all connected properly and working properly.
All software is up to date.
I have 2 Yamaha 115 outboards connected to the ECI-100
I need the STW.
The engine gauges can use either GPS data (if available) or engine data to provide fuel flow, economy units and speed.
I have a requirement for STW whilst fishing as well as to SOG.
I anchor in deep water (350meters) using a Min Kota, and I need the current speed. STW when stationary give the speed of the current.
From this I can work out how far from a fish source I need to be to hit the spot when there is current.
I am pretty sure this is provided by the engine when its on, but I cannot see it on the MFD
I believe the engine uses a pitot tube of some sort to derive the speed.

Under diagnostics Speed Through Water does not detect a source.
The NMEA data of the ECI-100 shows the appropriate sentence, though I haven't looked at it whilst underway.
Is it just that the MFD does not decode the STW from the ECI-100 at all?

If this sentence is not fully decoded in the MFD, does Raymarine have a speed transducer of some sort to connect to the STng network to get STW
