As mentioned in my other post, the rubber strap that holds down the rear of the muffler on my 2011 180 Challenger snapped in two (17hours). I replaced it, but found out that just this morning SeaDoo has issued a recall because of this and naturally my replacement strap is the old style, lol! (was only $12 from Riva).
Proper preplacement strap part number ends with 093
