Check the throttle arm on port side of engine... it should be FIRMLY against the stop (ie: You should not be able to push it away from the stop with your hands). Not "pre-loaded"... but held against the stop.
Agree- ONE battery at a time on-line, and must meet the demands of the ENGINE and the boat Accessories.
One final thing: Do you have a Smartcraft Instrument, perhaps one that's reading FUEL level?
