Out in the lake ...motor starts to sputter a little...stop and check gas...almost empty, change tanks. Motor starts back up...stalls after a minute. Can't get it restarted. Finally battery wears down. Stuck in middle of lake with the kids. Tried recharging battery....tried new battery. Just keeps turning over till battery drains. I'm not sure...but guessing maybe something got sucked up in the fuel line before I changed tanks. Filter maybe? I don't know....I'm not very mechanically inclined.. I have to guess its something rather simple preventing it from firing. Need some expert advice here. We have a short boating season here in Maine. Thanks

On an old motor like that, it is hard to guess. Take a compression test, and check for spark on all 6 cylinders. If those are good, suspect the carbs. You may have some sort of screen on the fuel pumps. Maybe that got dirty?
