Mike thanks for responding. I think I have the prop you describe. It does have the bent up ears.
On my way over to the boat yard the boat felt very sluggish and win I saw that tiny prop I thought there is the cause but reading about the prop it sounds good. 
What to do I would like a more responsiveness but don't want to spend a whole lot of$.
My boat has an A4 engine.
Thanks
Mark
