How far off keel centerline, left and right, is the optimal placement for water pickups on the cav plates. How far forward off the the trailing edge also, if that matters.

Call Mikey at Prime Marine. (909) 484-8329 with all the experience he has rigging ski race boats he would be a solid source.Quote:

Yeah, I want to make sure they are getting clean water. I also wonder about the bottom angle, 15 deg, 12.5 deg and flat. Not sure what the GN Raysons and the like are, 7 deg maybe.
my water pick ups are 7" from center and 1.5" from the trailing edge of the plate with a 20* slash cut on them
cp performance part number Cavitation Plate Style -10 AN Water Pick-Up
410-301101
comes in many sizes
I'm doing -16's and I making them now, so no need for CP's number but thanks. 7.0" off center sounds a little too close to center for some reason. Just from looking at other boats, I was thinking around 12.0" off center. But I am curious if there is some standard to this? Something that figures in the diameter of the prop + the angle of the bottom + distance from the prop, sort of thing.Quote:

Damn Jerry, I never noticed how many turnbuckles you have on that thing. Looks bitchin anyhow.
Here is a pic of mine on my Schiada.

Looking at Marc's, I'd say those are about 10-12 off center. And even with the pads, so about 1.5 - 2.0 from the end of the plate.
That Prime Schiada looks about the same also.
Mine are half way between the inner most turn buckles and the next ones out, and even with the turn buckle pads.Quote:

Mine are low because where they come thru the transom they go directly into the sea strainer for a clean connection.Quote:
