looking for original 3 blade prop size on 1995 36 MK11 with M35 diesel
"15 R 9" is stamped into our prop powered by an M35B....so 15" dia. with a 9" pitch

Ours is also a 15R9. 1998 mkII originally with the M35B.

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.

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..
