As I understand it 90% of the performance difference is generally in the engineering
I understood what you were saying but the point is that if I had dropped 2" of pitch I would have been over rev'ing....
The reason I mentioned the 4 blade is that I think you mixed up the rule of thumb that I've always heard for 3/4 instead of al/ss
DEF not trying to point fingers... I guess you and I have just had different experiences w props....
as it is, he's not buying a prop right yet anyhow so it doesn't much matter

Yep... totally agree. The fact is that props are so infinately variable that it's almost useless to say "this is what you have to do" vs "That is what you have to do". The ONLY way to know what prop is right for your boat is to actually know what you want your boat to do, and then try several different props until you get the one that's dialed in for your needs.
