What tha Moose says is pretty much spot on. You add his power and your touching $50k, my brother's rebuild was at the same number.....maybe a bit more, with trailer, original hull purchase, top, engine, etc..

However check out new boat prices and you will quickly find out $100k will maybe buy you a 23' boat as nice as Kens. Good luck.
