I am looking to install a dual battery into my boat and and would really like the two trays to match. Does anyone know who made the original tray Sea Doo used on these? I can't seem to find one like it... maybe they aren't made any more. Or alternatively, does any one have an extra like from a parted boat they will sell? My Speedster 150 also has the same tray so I don't think it needs to be from a Challenger specifically.
