Update......
I took my prop to a shop and had them look at it. The mechanic said the prop looked as if it was rubbing on the gearcase and that my propshaft was bent. I told him I doubt the shaft is bent as I have not hit anything. Point proven with a magnetic base and indicator setup (I'm a machinist by trade). The shaft didn't runout more than .002 of an inch. Pretty good I thought. I showed him that I have the "hydro torq" hub insert kit and asked if there should be slop in it. The bronze insert was really loose in the delrin insert. He said maybe the prop was torquing under load.
I bought a new insert and will try it out this coming weekend. Illinois river went up over 2 feet overnight due to some pretty intense storms this weekend so there was too much debris to risk a test run yesterday.
Any feelings that I'm on the right track???

Keeping my fingers crossed!!
