I just picked up a 2004 Utopia 185 and the test ride in the water was great. I brought it home and was checking over it again and hooked it up to the water hose and fired it up. Now I'm getting a rattling sound from the jet drive (engine's running very smooth). It wasn't noticable in the water but now that it's up on the trailer I can definetly hear it. I noticed that the intage grate/screen is hinged and could be the source of the noise.
