That Cat is also 3 years older and shouldn't you be comparing that 308 to an vio80? Also the SV100 to the 310 might really be the match up that should be here.
I work for a yanmar dealer and will say I’m impressed by yanmars build quality. In the 3 years I’ve worked on yanmar equipment I’ve never seen an engine failure yet nor pump failure that hasn’t been the fault of the operator.
