I have a 2001 342 with the Boss package. Twin 502 MPI's. Never did get to check speed with a gps however speedo reads about 71 wot. I have everything but the generator. I really like the boat. Moved up from a Checkmate 242. One of the main reasons I got the Baja over the brands you mention is the cockpit space. Even got married on the boat at a local waterfront rest, on 7/04/01. enough room to 5 people to stand for the ceremony. Well anyway I really like the way it performs.
