peculiar that the only two reported instances of this thus far are on the exact same year and model boat.. I'm going to chase the vent line, which I think I've seen when I pull the center floor panel, this weekend. I ran a tank from full to 3/16 and had no problem with engine performance in spite of the vacuum.. I assume you also haven't had engine troubles caused by this either??
