[Public-List] Motor Replacement continued

Fri Aug 21 07:52:57 PDT 2015

My mechanic told me that the most likely candidate is the Yanmar. Although apparently the original engine beds are gone and have been replaced to kinda fit the Vetus. We'll see over the next week or so what actually needs to be done to rebuild the Vetus and then go from there.
