I'm no expert but i have learned alot about my pump set up this year but still have a long way to go.
First i got all the measurments and wrote them down before i started,ride plate angle,shoe depth,loader depth,nozzle size.
So far i have only tested intake pressure @ 10:00 on the suction housing and made shoe depth changes according to what pressure i seen,next year i am going to test in 2 places.
you want consistent water pressure above 40 psi during a pass but not much above 60 or so.MOst impotant is what the pressure is @ on the big end.If it is too much you'll have shut down problems and not enough you'll loose some performance.You may be able to get away with more or less pressure,just depends.
Shoe depth is important,a good starting point is 1/8 to 1/4" above the keel line,don't go below keel line for any reason,a small change will make a big difference.I change it .060 @ a time with some shims that i made.
Also do you have a back cut shoe?Those hulls like a backcut, that helps with the lift on the big end.
You wedge the droop down and raise the ride plate to free it up .
Nozzle changes make a big difference in suction pressure also,smaller nozzle higher pressure.
I would get all the measurments and a garmin hand held gps and find out where your @ and make one change @ a time and see what it does,you'll be surprised what a small move may make and you'l learn wheather it was a positive change or not.
Give us all your measurments and nozzle size and will bench race all winter,by spring we will have it dialed in. :grin:
