Do you know what the OD of the stern tube on a 1979 Bertram 35?

If it’s got the original engines and running gear, you can probably get your question answered on the Bertram owners forum.
Many changes may have taken place since 1979!
There’s nothing like an actual mechanical measurement to replicate the exact part you need.

Post a good picture and I’ll show you where how to measure it. Shaft diameter is also a good way to elimate what it is NOT.
