Electrical not reaching panel

[Skidude17]

I have a mercruiser serial number 0F598365 in a ‘96 Searay where the electrical isn’t reaching the panel. When I put a remote starter switch on the starter, I get one solid click, but the engine doesn’t turn. I have 2 batteries with fresh charges. I ran it for a couple hours today, but it died on the way back to the dock. Where should I start looking?

Load test both batteries
Clean all four (4) battery terminals
Check that alternator is charging
