I've been searching the threads for over and hour and cannot find the answer to this question:

How many excess amps are available to run accessories (e.g. a bilge pump)? I'm planning to add one, but it won't be a positive addition if running the pump puts too much drain on the electrical system.

And yes, I see that plenty of people have installed 750 GPH pumps (approx 3 amps) without any negative feedback, but I'm hoping to get some actual specs.
