'85 Stars and Stripes Powerslot Prop Spray

I have a newly acquired 85 SS, fun boat and we've skied it a bit. Go figure, I haven't been behind it but 4 others have.

Anyways.. It's a mess with rooster tails and prop spray. I'm not positive on which prop is on it at the moment (I know, that would be helpful) and I don't have a picture of the spray handy (I know, that would be helpful too).

The humps/rooster tails aside, the weirdest thing is the spray coming from under swim platform. It looks like a jet ski with the trim all the way up, blasting a bunch of bubbly water out from the transom. I assume it's to do with the dish for the powerslot, and maybe some to do with the prop that's on there too. Is this normal for an 85 powerslot boat? Has anyone made it better?

Also, my hull/trasom is hooked down to lower the bow pretty far out from center on either side. Was that factory, or did someone do it after? It looks factory to me, unless someone did it wayyy long ago and it's blended really well. I've heard of it being both factory and fiberglassed in after.

Thanks, and I'll update with pics and prop info ASAP!

Spray/rooster tail

MC closed up the powerslot beginning with model year '86 to clean up the wake. I fabricated a concave trim plate for my '83 to accomplish the same thing:

Interesssttttttiiinnnggggg. Looks nice, beautiful boat too.

Does that clean up the wake far behind the boat (-35 to -22), or closer to the boat, like the "prop spray" I'm talking about?

Was that fabbed from scratch, or did you use some existing components for the plate and piece it together?

Custom Plate

I created a mold that mirrored the arch of the Powerslot on the front side and finished with a flat trailing edge on the rear. It was meant to lower the rooster tail and the hump at 15 and 22 off. It seems to work. Thanks for the compliment on the boat.

Any chance you want to make another or sell the mold if you still have it?

I'll look around the shop, but I think I got rid of the mold years ago. It wasn't very hi tech.
Just some bondo on a radiused wood base sculpted to the curve of the Powerslot. I covered it with packing tape as a release agent for the fiberglass.
