I took the Jaguar turn fin over to my Mechanicsville connection and had him put the whammy finish on it and just now mounted it to the sponson. This fin is really nice and I like the big machined washers to securely hold it in position as well as the huge range of adjustment Bob puts into these. also the pic is deceiving, there is more curve at the lower part of the fin than the pic makes it look like. Hopefully I will get the two motors broken in this weekend using my 80 Crapshooter and then I'll wait for the next nice weekend to get the Jag wet.
