prop question

[smokeonthewater]

well that's possible but I think it's more likely that it was due to a better designed prop... I don't believe that the alum flexes that much (some, yes) but rather the manufacturers don't generally put near the engineering into a $100 alum prop that they put into a $400 SS one.... 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
