Has anyone tackled the removal and replacement of the rear Aux. Fuel tank on the Carver 355/356 AC/MY. I know Viper says cut the swim platform open and do the R&R that way, was wondering if anyone tackled getting out thru the aft cabin head panel? Elliott, had posted some pictures from back in there and I wondered if Elliott thought it would be possible to tackle the R&R of the Aux. tank from there? My neighbor's 2001 356 aux tank let go this winter and our 1998 355 is showing the signs ours is about to let go too. Gas smell in aft cabin now and then, same symptoms as my neighbor was experiencing. The $5K estimates noted in a past forum makes my wallet sick! Also if someone has had this happen did Carver Yachts step up to the plate with any help with the cost or supplying a new tank? Is there a non metal replacement tank?
