I am looking at a 1970 Cal 43 for sale. Cal only made 14 of these boats so there is not a whole lot of information available for them. The one I am looking at is hull #2. The boat is in great shape in my opinion. It has a Westerbeke 4-107 in it with about 400+ hours. Does anyone have any information on Cal 43s or on the W4-107 engine? Thanks.
