Most of these were left overs from building electric boats. A few things from gas large scale boats. Most items are new and in the bag. I believe the stainless turn fins are Virginia Sport 40s. Pictures are part of the details, I’ve been out of hobby for 7 years plus, probably can’t answer many questions by this point but I’ll try my best if needed. Plenty of OSE part numbers on bags to look up prices and get specifics. The turn fins & carbon battery trays alone will probably cover the auction start price. The fighter cat motor mount is definitely a hard to find item by now, it already was back when I got it.
