the slip would be around 8% if its the srx and running 23 pitch. that is good for srx prop.
it probably is 23 again because the blades are bent down not up, and you added a touch of pitch to leading edge, so 23 pitch again.

the main thing is it it going fast, so slip dont realy matter, the boat looks good too.

what is pull away like ? is it better with the ring you made for gearcase ?

and will you be putting solid mounts in the bottom now you are running surface ?
