    Water Pickup

    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.

    I asked a similar question and was told that due to airation by the plates, I should consider moving the pickups under the boat out of the prop blast. I'm working on a true flat though. On your cruiser I would think back more would give you more lateral options to stay wet and out of the prop wash.

    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.

    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.

    Julian rigged the Biesemeyers with a single pick up under the boat (at the blast plate). If that comes loose or fails at speed your boat will likely sink.

    I have 2 #12 pick ups separated by 9.5 inches (centered) 9 inches behind the transom. I still use the blast plate pick up, but mine is set up for the oil cooler and v-drive and I check it for tightness every trip.
