1995 17 ft Parker ex. NC Wildlife boat. All of the Parker boats that the NC Wildlife uses have a heavy box-like brace around the splashwell that adds strength to the transom which allows them to over power them. My 1995 17 ft Parker has a Johnson 150 and my 2003 18ft T-Top Parker has a Mercury 200 . Both boats handle the motors well without any transom damage . Is this feature just for commercial customers and is there any other modifications on these two models other than the transom brace?
