Drain on my main boat motor battery
#5
Sounds like you could have a short somewhere. Boat stereos are basically the same as any other car stereo other than water resistant. Wires are negative, positive( powered all the time ), and ignition which turns the stereo from standby to on or ready. If yo do not have a dedicated switch for the stereo or accessory, the positive and ignition can be wired together. This would make the stereo in "ready" mode all the time but is not "on" and uses very very little power.

The battery s witch is just that. Wired inline on the positive between the battery and the fuse block. There are many variations of these from Perko, BEP and others. On-off, bat1-bat2-off, VSR(voltage sensing relay) and so on.

If you decide your in the market for a switch, I have two Perko's left over from my boat build that I could make you a great deal on(I went with BEP, smaller).
