When I installed the Universal M-25XPB into my Catalina 36, Norm at WestByNorth (good guy!) HIGHLY recommended a flexible coupling for the shaft. The existing engine in my Ontario 32 (Yanmar 2QM20) has one, and I think it may be partly responsible for the quiet, smooth running of the 2-cyl. The Beta's COME with one.
But Yanmar recommends against them, saying they make it hard to get the alignment right.
What say you? Are flexible couplings A Good Thing?
