Len, I have never done that, but I do find it to be stable, ie)not drifting 
at all. It seems I get the same RPM vs boat speed as I always have. I'm sure 
its not accurate, but all I need is repeatability. With the old prop it 
would max out at 3300, then with the Kiwi only 3000, and the pitch change 
clearly did show up on the max rpm.

How do you calibrate your tach?
