We are going to install a 2000 watt inverter in a 1989 Prestancia. I understand the cables have to be as short as possible and large enough to handle the current. Thinking of installing it beside the hot water heater with the battery bank on the other side (and other side of the boat). Any thoughts? Comments? Lessons learned?

A 2000 watt inverter may draw as much as 200 amps at 12 volts when fully loaded. For a wire just 2 feet or so you might get by with 2/0 battery cable. For the slightly longer distance you're talking about (10?) I think 4/0 would be the minimum size.
