Battery Isolator switch and Perko switch

[Rranger]

If beatennto death sorry but have a perko switch installed and looking to add a battery isolator switch.1994 135hp merc outboard. Do I need an alternator protection device to prevent a power dump. If not should following this pic be my quite.?

Excluding the line to the alternator.

It’s either the isolator or the ACR. You can’t have both in the circuit

What battery switch?
Starter typically goes to “common” where you currently have the power panel connected.

Sorry about first pic I posted, the one below is a better one for my present setup with out having yet installed a ACR or Battery Isolator yet. Which is my point is one better than the other? I can get a 140 amp Battery isolator for $40. Main concern is keeping starter battery charged, which I understand this will do.
