Does anyone know if there was an option for dual batteries on the 200 Sport Nautique or for that matter the 200 Nautique? If so where did they install the second battery? I was considering adding a second battery to my boat but for the life of me I can't see where one could possible be mounted. The single battery location is in the port rear locker but there's no way to fit a second battery there. If anyone's done this or seen one I really like to see where that was installed.....
