Let me start by sending my best wishes to those with family or freinds in the Gulf states devastated by Katrina. My family and I have you in our thoughts.
Secondly I have taken liberty with the word "wheelage" if asked it is a complete "BUSHism".
Here's the scoop 330hp Cummins 1.5:1 gears with 3 blade props cruise= 26 kts @ 2400 rpm. Top end 2800 rpm @ 31.6 kts. I'd like to go 4 blade for 2 reasons, smooooth ride and increased performance at cruise speed.
I'm looking for some info on 4 blade wheels; specifically sizing from some folks who have experience with this package. Hell for that matter anyone who switched from 3-4 blades can give me a hint if the cruise numbers go up. Thanks as alway for the help.
