Yeah I wasn't buying it either. The engines is brand new from Beta. They had a dealer perform all sorts of tests, but can't figure out why I'm getting steam. Suggesting now that my exhaust run is too short. But, I have two of them (catamaran), and the exhaust on the other side is just fine. I'm going to give them some more time to rectify before I end up stirring up too much trouble.
