Re: Identify this lower unit?

David, it’s tough to tell without a ruler in the photo for size, but it looks to be smaller than the Speeditwin lower unit. And the number seems early. Without seeing it in person, I think it looks like something from an early Sportfour or Elto Super A.

Edit: OK, a little more research indicates that the bolt pattern isn’t right for the Sportfour or the Super A. Those had the bolts outside the exhaust inlet. What size prop will fit?
