Hi all,I'm a relatively new owner of a 1980 Hunter 30. I have almost no control when putting my boat in reverse. Unfortunately, I'm not sure what kind of prop I have, the size of it or the size of the shaft. I'm pretty sure it's a two bladed prop and most likely it's the original. Can anyone point me in the right direction for controlling prop walk or possibly changing the prop to a 3 bladed one or feathering one that would give me better performance especially in reverse.Any help would be greatly appreciated.Cheers!-Bryan
