If the “engine hatch is wired to the dead port motor”, by linking the batteries (like you would to start that port motor) wouldn’t that give power to the dead battery and its accessories? All boats have a link/emergency start for the batteries don’t they?

Maybe the battery isn’t the only problem.

You can usually power it back through the switch to lift it enough to solve your problem. Also if you remove a side vent, the pin can often be reached which will unhook the ram at the connection point

May be able to "back feed" through accessory (cigarette lighter) plug with a "jump/booster pack".

Thanks for that insight. I ended up reversing a boost box through the 12v cigarette lighter. Now looking at a bad inverter that wasn't changing from the 30A shore power inlet.
