here is another link to a westerbeke 30 that is not listed in the manuals section... it is the newer style "Westerbeke 30" than what is listed in "manuals" section
this is the stock engine that is in a 1977 cal.... the 4-91 currently shown in the manuals is for the earlier W-30 engine, and it was called A "Westerbeke 4-91", and was installed in earlier boats....
if someone could post this there, it may be helpful to others..
