Yanmar vs Universal
FWIW: I did a lot of research on engines when I repowered. Basically, both Yanmar & Universal owners seem to be very happy with their engines. I didn't hear a bad thing about either. It seemed to me that there were two main differences that may or may not matter to you: The universals seem to be able to fit into tighter spaces. Though the overall dimentions are about the same, the Universal's transmission shaft is a little higher than the Yanmar, thus allowing the motor to sit lower in the bilge. The overall result is that the Universal will sit about 1.5" lower once it's installed. I'm comparing the Yanmar 2GM20F to the comparable Universal that they typically swap out for the Atomic 4.The Yanmar, however, has a 5 year warranty vs the 3 year that Universal offers. Having no experience with either, I went with the Yanmar because of the longer warranty but I believe either engine would have given comparable performance, and the Universal probably would have been a better fit.Good luck with your decision.Allen Schweitzers/v FalstaffC-30 Hull# 632
