John,

Hope that solves your problem, and if so, glad I could help.

I've seen the stainless flaps on somobody's website, but I don't know where. If I get a chance today I will look. My 88 Comp came with stainless SuperTrapp "mufflers" which evidently were either an option, or only used for a little while. One of these is missing and I can't find a replacement. It was taken off when the boat got swamped 10 or 12 years ago, and never put back on. The friend who owned the boat divorced his crazy wife and took a job in DC, leaving the boat in Tennessee. He called and just gave it to me last July. The Supertrapp mufflers attach to the transom where the flaps normally are, so I have ordered some thru hull fittings, and flaps, and plan on converting mine to flaps. I had forgot about the stainless ones, but they may be better than the rubber.
