Don’t go crazy on electronics, get why you need for YOU use YOUR boat. Some folks will talk you into spending $15k 20k…
A couple of years ago I redid the electronics on my 53MY. I went with a pair of 9’ Simrad GO9 touchscreen, one for the FB and one for the PH. On sale at defender for $499

. I also installed a Simrad AP and considered adding a radar but decided I didn’t really need it for our use. It’s all NMEA2000 so very easy to install it all. If I needed a radar I probably would have added an extra MFD at each station.
The Simrad GOs are pretty nice displays, not as fancy as some Garmins but they work well and very customizable. The interface is pretty good and intuitive.
If you install a pilot make sure you use a rudder indicator (NMEA) as the « virtual » indicators are not accurate.
I just added a Simrad wireless remote for the pilot which works great.
As a full time captain I have used a variety of systems over the years from Furuno Navnet and Navnet 3d, Garmin touchscreens, Raymarine including big Axioms on our 35’ tender. While I like the big Garmins (and hate the Rays), the little Simrads are perfect for my 53, after all they got me from Miami to eastern Tn a year ago
