I have a 2007 176XT which was upgraded to a 24volt trolling motor by the original owner, with the third battery being stored in one of the rear plastic storage bins. I called up Ranger or Stratos or whoever it is that answers the phones down in Flippin Arkansas to inquire about getting a bracket for mounting the third battery in the rear compartment of the boat with the other batteries like I had seen on the webpage for the latest 176VLO. They sold me what they called a sump board(part number 4759094) which is what they use to cover the bilge pump area in order to mount a 3rd battery for 24volt trolling motor setups. For $30 delivered I figured it was worth it in order to get one of my storage compartments back, but they were not able to tell me if it was secured by anything or if it just sat in place. So I am wondering if any 176VLO owners with the factory 24volt trolling motor setup would be able to tell me if their sump board is just set in place or is actually secured to the fiberglass with screws or something?
