You ever worry about the boat battery? How long can it run the pump? Are you charging the boat batteries or just letting the motor charge them while underway?
Batt drainage is not an issue...unless your alternator isn't working.Most draw less than 2 ampshttp://www.depcopump.com/catalog108/23.pdf

Most newer motors with auto-type alternators put out 40-60 amps - no problem there - but my old Black Max does 10 amps total on a good day at speed - less at idle, so I am actually slightly draining the batteries when trolling with a depth finder, gps, radio, and livewell pump running. :( But another reason to have 3 batts on board, with one fully isolated...
