Prop ID

[kevdp4]

I have been running this prop for 14 years on my boat. I have been very happy with the performance of the prop but I have spun the hub twice now. It is a four blade polished stainless that has no scratches or dings. I cannot tell the pitch of the prop, I assume I can measure the diameter.

The only number is F7RM31194002 on the hub rim.
Can anyone tell from this number what I have? (Pitch and diameter)

I would like to have a new hub pressed in but I don't trust the reliability so i probably will get a new prop. Would like to get the same setup.
