    Probably O’Reilly Auto Parts, NAPA, AutoZone or similar store. I have a 16 ft fiberglass bass boat.
    One battery should be sufficient??? Wouldn’t have room for say 2 29 group….

    If it’s only for those two units, probably OK. But if it’s your main battery, used for all accessories and cranking the outboard, get a group 31 battery. You don’t want to have to rope-start the outboard after a day of fishing. Charge the battery fully after every outing, preferably with an onboard charger. There’s another recent topic here about proper wire gauge for sonar units. Check it out.
