    2.5ltr to 3.0ltr conversion- OD not mating up.

    I have slowly been replacing my tin 66 Starcraft Sunchiefs original 2.5 liter with and "R" drive with a 89' GM 3.0 liter and Alpha 1 drive from a donor glass boat. Engine pretty much fell into the original foot print with only slight tweaking being needed. Gimbel and thrust plate also mated...

    3.0l Mercruiser Year ID Help

    I am having trouble ID'ing the year of my newly acquired 3.0l Mercruiser 130hp engine by serial# to determine exactly what I have. The 3.0l and Alpha1 drive came from a single donor late 80's Renken glass boat and obviously mate up nicely together. I have used the stickeys to no avail. Serial#...

    1966 Sunchief Restore II- In the Beginning

    Got started today by removing some interference and then the OD assembly from the transom. All components looked reasonably decent to my untrained eyes. I have decided to covert this to an outboard set-up due to $$$ constraints which I know is making some of you cringe... However with some of...

    66 SunChief 21'

    Found this 1966 Sunchief last week- hull, hardware and trailer look great. Owner says he posseses all engine components but block is cracked he thinks and it is completely dis-assembled... Would anybody venture a guess what it's worth as described or what you'd pay ballpark?
