I am currently having my 1974 222aquasport redone, I did most of the stuctural stuff myself, transome, and deck, and stringers, but hate finishing work, so I decided to have someone do the rest, and decided to have mine look more toward like how a boat looks out of a mold because I figured I would rather go the extra mile and have it done the exact way I want, so far he has put 130hours into it, and It seems about half way so I,m thinking 200-250 hours total of work. It depends on the hourly rate your get, the least I think you will find is 25 and the high will be 50-75 easy I think depending on the place and the need of money. Bottom line is you can buy a new boat easy for what these guys have in their boats and what I will have in mine, especially if you buy a new motor!
Also you have to figure all of the new parts that your have to buy, gauges, hyd steering,list goes on these nickel and dime the Sh*t out of you, but you have a boat laid out exactly the way you want it, which is why I am doing mine, I have had alot of average to high end manufactored boats and always want something a little different and unique.
