There are some CF posts elsewhere on this forum you can search. We have over a 1000hrs on each of our 60's without any issue. They have been real champs. During our stay in South Africa I had engineservice from Yanmar who also supply SD60s to the local builders and the only issue they've reported in 3yrs (as of Jan 16) was where the shifter was not aligned correctly between fwd, neutral and reverse causing malfunctioning. Our experience has been all good.
