My feeling is that you either have to leave the system all on or all off. I think disconnecting individual items is counter productive. Any lengthening of battery life you would get from disconnecting the solar would be minimum. If the boat is in the water, the bilge pump needs to be on, the system needs to be awake, and because it will use power in this mode it will need to be charged. If you take the boat out of the water you can turn everything off.
If you leave it in the water for the winter in a climate where it freezes sometimes, the batteries will not be able to be charged at low temperatures but will continue to be providing power and so will eventually run out. In this case I recommend disconnecting the lithium batteries and running your bilge pump off the start battery.
