Finding Good Prop Pitch to Begin
First off I do not have a Tach and will not have one for a while.
The ski is out of the water for some paint so no way of testing.
I'd like to find a "ballpark" pitch to begin and then go on from there.
The current prop is wayy too much for this little 1200, Its a 14/24 Dynafly. I'm thinking of starting off with a 13/20-21. Last time I was out with the ski it ran 69.4 with almost no plate angle, riva sponsons on the down position, and trim tabs shimmed 4.2mm. I have the ski set up for mostly handling as you see. The Goal is 72-73 with great handling.
Riva Trim Tabs
Top Loader Intake Grate
Stock Uncut Head
Just purchased a Speedwerx head but have done no testing with this set up. The stock gasket was letting some water in so I'm sure that slowed me down a bit too

A 20-21 will most likely still be too big.
What size exit nozzle?

I want a little room to grow as well thats why I thought a 20-21 would be best.
