In Gulfport Ms. there is a 99 45" Marathon that had Katrina water almost over engine , but not over the floor inside. Inside looks great, but I can only imagine what Gen. and all wiring beneath floor looks like. It has been sitting since Katrina and really looks nasty outside. It is handled by WWW.salvagedirect.com I do not know if it will be auctioned or sold as is.
It would be a great place to find hard to replicate parts for Marathons and others. Dan
