Thanks Brian. I did not mention that it is a '01 Outback. I bought it this winter and it was the third time I have had it out. Sorry. I will check the prop tonight. If it does appear to have backed off slightly, is that something I could tighten with a wrench or does a pro need to do that?
Another question, when I was under the boat looking at it after I got it out of the water, I noticed a chunk out of the wooden runner on the left side of the trailer at the back. The carpet was cut and a sizable chunk out of the wood. I never noticed this before. My question is, with the guide poles on the trailer is it even possible that the prop could have hit the runner while trailering? If so, I would think that I would have felt it. Maybe it happened when the last guy had it. I just thought it was odd. Thanks.
