Let me start counting of what I have and what I want to add:
1. Motor starter
Possibly not fused.

You are probably right. The motor itself already has a fuse inside the
motor for the starter. I assume we don't need another fuse for the
same thing in the panel. I don't know for sure because I am still
reviewing the wiring.

2. Bilge pump
Possibly fused separately and not connected to the main breaker... but
directly to the battery.

You are exactly right. Although the panel in the boat has a slot for
bilge pump, the slot is not connecting to anything. The wiring for the
bilge pump actually goes directly to the battery switch and bypassing
the panel.

6. 12-volt outlet (not sure what it is for?)
A blender, of course...... daiquiris anyone?

May be for a live-baits well that I will add to my boat
