I have a "new" Blue Seas Systems plastic battery box, model 4D, which would hold a single 4D battery. This thing has been kicking around my boat since I bought the boat, and my guess is that it has been aboard since the boat was new, circa 2003 or so. When I got the boat it was being used to store Racor filter cartridges (new, in wrappers). As near as I can tell it has never been mounted and never had a battery in it. It's a bit dusty but otherwise in pristine condition. I'd like to get this off the boat. New they run about a C-note, but I'm willing to let it go for $35, plus shipping or whatever other arrangement we need to make for you to get it from me. We are currently lying Chattanooga, TN, at the riverfront docks. We'll be here at least another two weeks. From here we will be proceeding downriver all the way to the Ohio and thence the Mississippi. If you happen to be looping this season, we'll probably pass you and can arrange a handoff. Email me directly if you are interested. -Sean m/y Vector lying Chattanooga, TN http://OurOdyssey.BlogSpot.com
