Hey guys
New to the site . I'm having a hell of a time with this ski. It was left out last winter not winterized. I pulled entire exhaust system out and inspected. So far I have a cracked expansion chamber that I can easily weld. My curiosity lies in the center of the extension pipe that connects to it. On the outside it looks great. The inside however looks to be about 75% blocked by a swollen section. It looks too perfect to be ice damage though. It's almost as if it was designed this way. Can anyone verify ?
