Speaking of water incursion. When removing the exhaust I found the newer style rubber flapper I installed just 2 seasons ago is toast. One half of it just tore right off. I'll have to try and fish it out if it's still in the y pipe. Anyone have any thoughts on those flappers? Seem like junk to me if they're going to fail that quickly. The metal one with the rubber coating survived almost 20 years before the rubber wore off. Even then the metal frame was still there and I could tell it needed replaced by the clanking.
