Bart,

One factor that may influence IVO prop success is properly remounting
it after removal. The info I got from Johnny at northwest-aero.com
- a news post - is that the knurled plates are really needed and
that when the prop is removed it should marked and later remounted
in exactly same position/orientation it was before. Otherwise the
"knurls" do not seat together the same way and they wear off and
the prop goes loose and you will likely have problems.

I'll second the factual notion.
