I'm in the process of rebuilding a 1985 Chris Craft Stinger it has Twin 454 I/O with Alpha One outdrives. The engines will be a mild 310 HP. What kind of props should I go with I would like to be able to run 60-65mph if that is possible with two mild big blocks.
thanks for any help.

mercury has a "prop selector" feature on their web site that's pretty good too. www.mercurymarine.com

How many RPMs do you want to turn?
I'd start with 23's...maybe 25's?

I would have to say go with the 23's.
Do you have anyone you can borrow from that will let you do some prop testing?
If so thats your best bet
