Hi Ben

I don't think I'm going to be able to help there. Oyster couldn't supply any written info for the taper, which is why I sent the photo to Brunton and they then worked from that. I think it's a fairly standard taper - perhaps if you show your engineers the photo of 'Athene' they may be able to confirm that. Sorry I can't be more helpful.

Hello again Gordon,
I was hoping you may be able to help me with written info on the taper dimensions of the 435 prop shaft from your propeller install. I'm currently working with engineers on a new prop but I can't find anywhere the shaft taper dimensions although I believe it may be a standard SAE size. As we are not hauling the boat yet I was hoping to get the ball rolling in regards to the new prop while she is in the water.
You've been more than helpful so far and any info is much appreciated. Hope you are having some good sailing.
Regards
Ben
