Hello to all the experts:<br /><br />It's me again with something new that hopefully you can give me some good news/answers.<br /><br />First and foremost, my boat has been repair which, I 
decied to get a major tune up. It runs very good.<br /><br />When I took my boat out for a test trial just to see how it runs, I was so happy that I could have stayed on the river all day. Here's where the problem begin. When I was going up stream I know for sure that I hit a rock because my engine got so loud, I thought it was going to come off the boat. So quickly I got back in the main channel and continue my boating. I did notice that the engine stay louder then normal. So after 20-30 minutes later, I notice that the engine had started to knock or jerk. The knocking would happen only once every 3-5 minutes. So I decied to get my boat off the river before I get stranded. When I was putting my boat away, I checked it over to see any damage, but I didn't notice nothing. The only thing that I notice was that you could turn the prop by hand with no fiction in between. So, I would wait for your suggestion, ideas, inputs or whatever you have for me.<br /><br />Thanks<br /><br />PS. I fish on the mississippi river in God's country. La Crosse, WI
