That might depend on what size motor he has on his boat. My 90hp Merc 2strk will usually keep my Group 24 starting battery pretty close to fully charged, just from the idling I do at the ramp & running around the lake. And that's even when I don't run more than a couple of miles away from the ramp. My big motor, the guages, and the livewell pump are the only things run by that battery, though, as I do not have a depth finder at the console. My LS has it's own separate battery & the Hook 7 runs on the trolling motor battery (68ah AGM).
AND .... just to be sure that my starting battery doesn't poop out on me, I carry a jumper cable.
