I have a 1993 sea ray 170. Not the biggest but fun times on the lake. I have a couple questions. 1. There is a little chunk in the foot that is missing. Do I have to buy another foot or is there another option. 2. I currently have a 19" pitch 3 blade prop and have a little vibration not much but noticeable. I was thinking about going with a 4 blade but wasn't sure what pitch I needed to go with or If it would do anything at all. This is my first boat and not real versed in all this stuff. It's a 3.0 inboard motor rated at 4400-4800 rpm.
