View Full Version : PROSTAR 190 with LT1 Issues. NEED HELP!!

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!

OK, I will bite...

Even though your LT-1 has relatively low hours on it I would guess it is more than 10 years old. If you feel/hear the engine skipping a beat I would take a good look at the plug wires. They can wear out from just sitting around...
