It has been a few years so I cant remember the exact amount. I can dig up the receipt if it's important, but it will take me a while. I think 5-7k. The inside of the engine compartment (transom+sides) was gutted right out to the exterior fiberglass. The stringers were completely removed from the transom to the bulkhead and I think even the bulkhead itself was replaced. Every thing was replaced, re glassed and repainted on the inside. Some minor repair was done to the exterior paint. I do have some complaints about the work but will discuss them privately. I don't believe you have a Formula, but this is who they recommend for structural repairs (for what that's worth to you).

I'm not as brave as some of you...took ours to Rich Sutphen to replace the transom...s/b finished in a week or so...
