[Alberg30] Alberg 30 Sail No. 335

[T. Kevin Blanc]

If it has an Atomic 4, the original prop was most
likely a 2 blade 13x7. The shaft is 7/8". There is a
keyway, but any machine shop will be able to help you
with that - it'll probably be dictated by the prop you
buy. Some folks do away with the keyway if you
carefully fit the prop and shaft.

You might want to do some research on the most
appropriate prop. A three blader (different size and
pitch) might be better if you don't care about the
extra drag.
