I have the same 50a (and 30) in the bow locker and it iwas a Tiara option at the time for the 52 (not sure about the 41). I responded to a post in the fall regarding this same topic. Trace the wire back and you will most likely find an automatic transfer switch probably in the ER of behind distribution panel. If someone did an aftermarket install it would still need either a manual or automatic switch or safety locked breakers.

Reel Magic has the right suggestion. Check with Tiara and you will most likely save a lot of time. They should be able to send you a schematic and tell you where to find the switch.
