I am going through the electrical power distribution wiring on my recently purchased 2001 Dauntless 160
This 2001 160 DAUNTLESS was re-powered in c.2015 with a 2015 Yamaha 115. The re-power was done by a certified Yamaha dealer. The boat got new gauges and a plexiglass panel that holds the gauges and switches. There are no breakers next to the switches. There are no fuses or circuit breakers other than the two shown below in Figure 1.

I added a sub-panel for the stereo, SONAR, VHF radio, and a cigar lighter socket.
Q1: What [circuits] do the DC main breaker and bilge breaker [protect]?
Q2: Should I add an additional fuse for the sump pump and navigation lights?
Thanks
