I have a 2005 Sportster Le DI with the ROTAX 947, 2-stroke direct injection.
I bought the boat used, and the previous owner had an aftermarket stereo installed on the aft side. The stereo is fused and wired directly to the starting battery's posts. I want to put in an on/off switch so I don't have to mess with the unscrewing the battery post's wingnut each time I want to add or remove power from the radio. Also, I want to install a USB charging port (for cell phones) and a 12-volt power outlet for plugging in my portable 12-Volt (120 watt) inflatable tube pump.
I'm considering adding a second battery, the deep cycle kind for running these accessories and also so I have a hot spare battery in the event that my starting battery dies. My current battery is an Autocraft M24-3 starting battery. I want the option to be able to charge both batteries with the boat's alternator, so I'm going to get a 4 position battery switch, like:
1.) Off
2.) 1
3.) 2
4.) 1+2
I'm looking at these two battery switches:

My question is four-fold.
1.) Do I need a battery switch with the (AFD) Alternator Field Disconnect circuit?
2.) Can my boat's charging system handle charging both battery types simultaneously?
3.) Weight balance is my biggest concern, so where is the recommended location to install the second deep cycle battery?
4.) Where is the recommended location for installing the USB charging port/12-volt power outlet, such as this one http://a.co/aXWwacK
