Keuka Lake, NY? If so, yep! What year is your boat? If its a 1:1 direct drive, you should have a 13"X13" also, check the condenser! Don;t trust Bosch anymore, they are no longer best (sad huh?), many people are having problems left and right with cheap points and crap condensers out of the box...

For your carb, now its dangerous but sure is a great way to see whats going on, is to: Take off the dog house and have someone else drive at WOT and watch the carb with the spark arrestor off. See if the secondaries are opening up and see if the venturies are flowing correctly, you might have some crap plugging up the carb... And if the secondaries aren't opening up all the way, open them up manually and see how she runs!
