I hate to be the pessimist, but afterall, it is my nature...
Scott, you just put together a list of what it would be worth to part it out, not to put it back on the water, and certainly not what it would take to make it competitive again.
Steering and drive are going to cost at least $1500 to be gone through.
I actually see less than the 3-5K in Hull/Deck work. Maybe $2k if you can do a bit of work yourself.
Carb, junk it and just buy a new one, you'll save money.
By the time you start adding it all up, plus time and labor, you're gonna be into it for for close to 20K
On top of that, the boat needs paint and a rub-rail.
It needs all new interior, and all new controls and gauges, (full deal, cables and wiring). And, you need someone to put it together.
I don't mean to be farting in church, but, If SLP wants to do this, I'd rather he knows what he's getting into.
