My boat has a 300R, it has power steering, the cranking battery was mounted on the far right side of the bilge ( starboard ) then the power steering pump was next to it, so if for some reason you had to replace battery or even get to it you would have to remove the power steering pump, so the dealer swapped them around, not sure if this was an oversight by the factory or what. They did not have any problem flush mounting my Lowrance HDS 16 Live at the bow. They should have boat ready today but it will be next week before i am able to go pick her up, have a dang tourney tomorrow, about to leave out here in a couple of hours.
