[Stillrunning]

I used two sheets of 3/4 ply that I used west system to join them with a few screws to pull them together I then covered with a thin sheet of fiberglass. I had to put on one section at a time and I believe it was in four sections( when I say one scetion at a time it was secure one add the next) .I had two people helping one mixing the resin and the other helping to put it in. Instead of using thru bolts i drilled holes for wood screws below the water line then any other holes I had for tow cleats, scups etc.. I used a small peice of wood with a wood screw to pull it tight (the small peice of wood is on the out side like a washer). Then I collected all the different clamps I could find and went to town. Places where I used the small peice of wood as washers rub some wax around the out side of the hole because resin will squirt out and the wax will keep it from bonding to outer gelcoat. Using this method you will not damage the outer gel coat. I then came back and drilled out all the thu holes and coated them with west system. I used West System on recommendations from a friend who works on boats its more expensive but he siad don't go cheap on the transom. One other thing is to dry fit everthing first to see which way is best to install the new transom. I hop this helps some.
