[C320-list] Gori-Prop buyer question - Not a propmanufacturerdebate

[Chris Holt]

Do you know what Yanmar you have, the Eurpoean version or the Japanese 
version?
I believe the change from the Japanese Yanmar to the European Yanmar 
coincided with the transmission ratio change, correct?

Also, how many knots on average can you cruise at?

Thanks for you response!
