Brian, on Peregrinus, a B&G (Simrad) AC42 drives either of the Raymarine drives most of the time. This setup is in place since 2013 and so far, so good. Anyone with a 24V AC42, like ours, needs a DC-DC converter to 12V on the clutch output, as the Raymarine clutches are uniquely 12V even on the 24V drives. This is probably a non-issue for you.
We do run the drives with the Raytheon T-300 computer via its ST7000+ keypad about once a week.
