Okay Laduckhunter, I do see some great lines in that boat. I also see many years of service from her too. I see you have a Merc 115. But it doesn't look like the tower of power series. Is it a V6?
The variance in costs from one person to the next has a lot to do with a few things. First the material one choses. If you go the cheap route and use really cheap particle board wood and some can spray paint as a sealer, well, you will be doing it again next year or sooner. However, if you use quality exterior grade plywoods, Arauco, or even Marine grade plywoods that are factory glued together to be use outdoors and laminate two sections together to achieve the correct transom thickness and use either polyester or epoxy resins and the correct fiberglass materials, then it is going to cost more, BUT will last longer then you will ever use it.
There are many such project currently being worked on these forums. And there is even a "how to" section on transoms, stringers and floor replacement that you should look up and read to get familiar with the concepts and see how things proceed. Very good informative reading for sure.
As you work on your boat project, remember if you cut corners and do shortcuts, you will be looking to do it again down the road. But if you take your time and use quality materials and resins, it will last longer then original for sure.
But your boat does have some real appeal to it and I see a very nice Bass Boat coming out of this one. :thumb:
