I do not have a definite line in the sand for what was the last boat with the original transom angle. I know that Warpath, Warpath II, The Team Apache Boat (banner boat), all have the earlier transom, and I think Stinson said in a prior post that it was only the early boats. Off the top of my head Lethal Weapon, Island Runner, Shaka, etc. do not have it so the change took place somewhere in between, I know it does not answer your question too well

. Anybody?
