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:


spoon 004.jpg

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