Prop help

[Andy Slaviero]

I'm new into this hobby, and in need of some help. ??? I currently have a Aeromarine 36in Sprint cat with an O.S.81-VRM, and an Aeromarine 44in Avenger cat with an A90-HP. I'm in need of some help with prop choice for these boats. They will be raced this season, and I have no idea on were to start. Any help will be greatly appreciated, and would like to buy them allready done.

Thanks,

Andy

Andy,

I think a 255 on the 81 CAT and a 260 on the A90 CAT.

Thanks,

I found this site a while ago and it gives you good starting point for all sorts of boats and methods of power.
