It’s a Volvo penta prop so the hub is already installed on it, it just slides on. My only thought is that since it had already a different size prop, maybe the thrust washer isn’t the correct one.
First time boat owner, I have a 2005 four Winns horizon 200le with I/O 4.3 Volvo penta) that Ibought used. Previous owner put an different size prop (14 1/4x21) I bought the stock size prop ( 14 1/4x23)as the other one had damage. My issue is that if I tighten it any more then finger tight...
