Seatalkng/NMEA2000 Power

[ledouxjj]

I am just finalizing a new dual MFD Raymarine system using two es128 MFDs. I have also installed a Maretron NMEA backbone system to support monitoring all the engines, weather, etc. My first question is this, I believe the Maretron cables are of heavier gauge wire and therefore a lower power loss. So should I be powering the entire NMEA2000/SeatalkNG system from the Maretron or Vice versa?

Second question is since Raymarine does not make a 183 to 2000 converter am I safe to assume I can use the 183 interfaces at both MFDs to connect to my ICOM VHF and SSB Radios.

My first try was powering the NG/2000 buss through the SeatalkNG and connected my third party Class A AIS via the SeatalkNG/NMEA2000 adapter but I was not getting all the AIS data sent to the MFDs. The unit is an AllTec.
