Yes, it's a great hull. The TSC1 was an evolution of this hull so it's a little better than this hull, but this is still a very good hull. Good tracking and spray too, ahead of its time when it came out in 1990. I've had two of these and I currently own a TSC1 and a 200 so I'm a pretty good reference on this subject.
I'd look for a pullout GT40. Other than the ECU parts are common and plentiful Ford parts generally. Plus you'd have an extra GT40 for parts. If you want to fix the current one they are pretty simple to work on.
I'd be more worried about interior costs which can run into many thousands of dollars quickly.
Carpet sucks to replace in general.
Figure pullout engine: $2,500, Interior, $3,500, that's a decent boat for $6K best case (?)
