Motor for Columbia 28

[4play]

I have saved a Cloumbia 28 from the junk yard. Just finished the hull and now starting to work on the inside. It is ready for sailing around the bay and now I have been looking for a 9.9 hp to mount in the motor well. So am I looking for a short, long or xlong shaft? It looks like to me the long shaft should work but this is why I am here asking.

Thanks for the help.

Long shaft only!
