Classic Australian Wooden Power Boat Association

I have 2 Austral props a 12IRSF and a 12JRSJ i would like to know what pitch they are .I have tried to find a sight on line with no sucess .

Like me, you have probably been baffled by the code stamped on the boss of Austral props. To clarify I emailed the good people at Austral and received this helpful response....

Typical numbering is 12JRSJ
This means 12" diameter ,J = 15" pitch, R = RH rotation (clockwise), S = Supercup and final J = 1" Morse standard bore.
Pitch codes are as follows
F=12, H=13, I=14, J=15 and K=16
Bore codes are
H=1"SAE, J=1"Morse, K=1.125"SAE

Now the mystery is solved.
