Nice looking boat. Am I right in assuming it's a 43" hull? If so, it would be legal to race in sport 60 but not in scale, if that is what you were planning to do.
I'm guessing that the motor is a K&B and, if so, will be hard to find parts for. You may want to swap it out for a CMB as they are current and parts are readily available.
One thing you will need to do is to put braces between the rear of the hull and the tails. If they aren't braced, the tails will flex and break, as will the hull where they are attached
