Thanks. Found a 15 x 9 3 blade in my spare parts and wanted to verify. Changing out my current folding prop due to barnacle fouling and subsequent engine vibration. curious to compare performance.

what is the ratio of your transmission? If this is not original anymore the standard 3-blade 15R9 is not matching.

John-
Your transmission may be the same as ours: Hurth ZF10M. If so, the "A" ratio is 1.79 and "B" ratio is 1.86. I believe A means the forward gear ratio and B means reverse..
