I need an isolator for my boat, it has a 1985 50 hp Mercury outboard & I have no clue what amperage isolator to get. I am running a starting battery & a marine battery for accessories. Can you help me with this?

That engine is likely only charging a 16 amps max…
I’ve got 2003 90hp merc 24v trollingmotor, batteries wired in series for 24v. How would I separate the 2 batteries to charge off motor?

When two 12 volt battery’s are hooked together ( in series ) positive terminal to negative terminal and negative terminal to positive terminal they become 24 volt. If you want to use both battery’s in a 12 volt application, connect the positive terminals together and the negative terminals together. Now the batters are in parallel giving you a large reserve 12 volt battery bank.
