Propeller size and shaft deminsion

[P69]

Sta Sea Dawn,

FWIW:

I have a 367, Universal 5444,  Hurth transmission, Walter V (RV20) drive with 2-blade RH prop.
At binnacle, move shifter fwd, boat goes fwd. move the shifter aft, boat goes in reverse. In reverse, propwalk is strong but I don't remember the direction clearly. I think propwalk in reverse is to port.

I am the only one of the owners of a 365...hull number 193...
that has a 17R10-1 1/8 prop.  I have the westerbeke 40 HP ...Paragon...walter v-drive...  The tranny locks into indent and goes 5 knots at 2000 rpm forward and holds in reverse and goes backward.  I can control prop walk with helm.  Reverses well enough for me to walk in and out of my slip single handed....I know everyone says change it...but it works.........seems to me if I change, the indent and tranny will reverse positions?

Is it possible that your propeller is mismarked?  The W40 (Perkins 4-108), Paragon transmission and Walter v-drive (R10 Pearson Special) should produce in forward gear a left handed propeller (counter-clockwise) rotation when viewed from the stern.  You can check this by running the engine in forward at low RPM in the slip.  If the shaft from the v-drive to the propeller rotates counter-clockwise when viewed from the stern, you have a left handed system.  Propellers are are usually designed for better performance going forward but this may not be obvious.
