Air bleed. It’s to make the pump run quieter. When am home I can send you a picture of the instructions to adjust it.

That would be great. This one is just wide open. Has cavitation getting on step pretty bad. Impellers are good.

So it’s not hooked up to anything? Should be hooked up to a fitting up top that has a screw in it. Right between your trim hoses. That would cause cavitation.

What’s you impeller clearance?)

Couple 85

A couple 852 I did awhile ago

Yup found the valve and where it was supposed to hook to. This one also has other issues with the gasket to the intake. Is the back of the pump supposed to be curved or flat?

That should be flat.

That much of a bend I’d be looking for cracked pump housing.

You have found your cavitation problem.
