New to this forum, and really need the help. I have a Prostar 190 with the Multiport LT1. Great boat with fairly low hours. Recently had the exhaust come apart at the muffler and caused the engine to die out. After repairing the Muffler leak, now the engine seems to "Skip" at certain RPM's. Especially at launch and around 3,500-4k RPM's. Certainly hear it in the exhaust note. Really trying to figure out what could be the issue. Plugs look fine, no leaks. Anyone ever heard of this issue before? Any help would be greatly appreciated!
