En el manual pone que se pueden conectar equipos NMEA o bien a la centralita del piloto o bien a la parte trasera del display de control.

How to connect NMEA equipment
If you have equipment on your boat that transmits or receives NMEA 0183 data
(e.g. GPS), you can connect this equipment to the SmartPilot. NMEA equipment
can be connected in any combination of these ways:
• using the SmartPilot computer NMEA input/output
• using the NMEA input on the back of the SmartPilot controller. (Refer to the
Controller handbook for NMEA data details)
• using the SeaTalk/NMEA interface (part number: E85001) to convert the
NMEA data to SeaTalk data.

Segun el manual admite las siguientes entradas NMEA:

SmartPilot computer NMEA inputs/outputs
Note: Do NOT connect more than one piece of equipment to each SmartPilot computer
NMEA input.
NMEA connectivity overview
Note: When connected to a NMEA navigator, S2 & S3 systems look at NMEA 1 first. If
NMEA 1 has no data, it then looks at NMEA 2. If both channels have the same type of navigation
data, NMEA 1 is used.
S1 Systems S2 & S3 Systems
The S1 has a single NMEA input/output to
receive and transmit information from
NMEA equipment.
S2 and S3 systems have two sets of NMEA
inputs/outputs to receive and transmit
information from NMEA equipment.

Según eso parece que si los datos de velocidad de la corredera le entran vía NMEA, esos datos podrian ser enviados despues via SeaTalk por el display del piloto. No pone que admita datos de la sonda,
A ver que te dicen de Raymarine
