Hello All,<br /><br />I had almost had a completely good boating trip until I went to load back up. when coming back into the dock I got a little shallow and hit something hard with the rear prop, it bent over two blade ends on the back and now with the engine running at idle out of the water it sounds normal, as soon as I advance throttle (in neutral) I get a weird vibration and the engine noise sounds allot different than before, I went up to about 1500 RPM or so. I first noticed this in the water when loading up since I had dropped of the family and put the trailer in the water, when I came back around to load the boat, I noticed a vibration and noise when bringing her around to drive onto the trailer? So any ideas where to start?
