If you get a new charger, the holes likely wont line up. Then, all you have to do is get a piece of starboard or some type of plastic cutting board, make a template using the old holes in the boat, fasten the board to the boat, and then fasten the charger to the board. That way you can use the old holes in the boat and not have to drill more. This assumes of course that the new charger will fit in the same area. If you do go new, and with MK, stick with the PC series as it gives you more options for battery choices.
