No idea if this design will work,any feedback would be greatly appreciated

Looks like it should push the air out of the way! How did you form it?

But kinda reminds me on my 1st attempt at a spoon, which didn't work.

Here is a picture of my epic fail, good thing it was just a prototype:




The problem with that one was it was too abrupt.

On my next try, I made a long shovel, it has a slight Vee to it. Now I can handle up to 3 inch chop.

If it is cavitating in glass smooth water, it may be the the pump shoe isn't sealed well.

Hammer and dolly,and anvil,aluminum was already somewhat curved when I started

 

[Paintman]

Mine isn't near as abrupt,pics are hard to take from the bottom but I think the transition is pretty mild

 

[Paintman]

Put a solas concord 9/15 pitch impeller on and it made a world of difference, don't think I'll even need the spoon now,hardly even cavitates in 4 inch chop

My manual adjust trim nozzle,no more pourposing

Can you measure how many degrees down (from hull plane) you ended up with?

Looks like maybe 7 or 8 but hard to tell from a photo.

It at the farthest point in the picture,I'm going to adjust it upwards next time I take the boat out,just trial and error I guess
