Info on Kaama props

Please help. Any one know what the stamped number on a Kaama prop converts to .The number on both my props is 18347. One is right hand and one is left hand. The diameter is 17" and they have three blades I have no idea as to the pitch.

Thanks

Re: Info on Kaama props

It seems that when you remove the lock nut the diameter and pitch are stamped in the face of the hub. Mine are 17X23. :evilb: I am looking to lower my top rpm by 500 .I am hitting the rev limiters now at 6000. The engines dynoed out at 600 hp at 5500.I am running 13% over drive at the out drive. I have twin disc transmissions but have not found the ratio of these yet.Anyone care to take an educated guess at what I should be looking for. I have read that four and five blade props are smoother with less vibration. Should I be seeking these as well.
