What is a good starting point for the ride plate? I heard 3 degrees, but is that up or down? Then what after that?

Depends on boat & set up! Try 2-2.5 degrees & that is related to the keel or bottom of the boat in front of the intake!

Make your adjustment at 2-2.1/2 (up) from keel line. I take my measurement from the bottom flat left or right side of the shoe as I know that its true with the Keel or bottom of the my Boat.
After a couple Full Passes, note speed...and how the bow and the Boat feel...then experment by raising and lowering the ride plate just a few degrees with SS Washers...and see how the hull responds. Just a few degrees make a pretty noticeable affect on my 21 Daytona.
I did'nt think you had a RidePlate and Shoe???

Hammer...
Are you running any kind of cavitation plates??fixed or adjustable?
I have a 21 Daytona 502, Legend setback, ride plate, place diverter. I get a little porpose at mid throttle that I can't get rid of.
thanks

Dean Nope no cav plates...I did have a very slight porpose...I dialed it away...with the ride plate. If I recall the plate was to far down (a few degrees)at the time...the hull was trying to pack air and lift but the lowered plate was pushing down on the bow...kinda fighting itself. This was at the upper rpm range, but now all's good.

Hammer..
Thanks for the reply. Never thought of that. I'll try dialing the plate back and see what happens.

One trend I noticed is that it seems the semi-v bottoms end up with more up angle on their plates than the tunnelhulls do. A buddy of mine that races (experienced with setups) started my semi-v out at 3 degrees and no wedge and ended up with a 3 degree up wedge and 4.7 degrees up on the plate. I haven't had a chance to see it at full speed, but I'm told that the only thing in the water is a patch of about 3 square feet. The sides are out completely (no spray off the sides). It's just on the verge of a porpoise and I think if it had any more up it would. I'm convinced that my setup is right on, and if I want to go any faster, I'd have to put some ponies to it.
I've seen lots of pump pictures (other setups) and compared them side by side and this trend (more up on semi's) seems to be pretty consistent.
Maybe someone with more setup experience could say why this is, or maybe I'm drawing an incorrect conclusion?
