replaced the rudder thingy it was bent and turned to far to the right he put a pencil on the shaft said that was allright I guess you put the pencil in the shaft and spin the prop if the pencil wobbles its bent so i replaced the rudder brand new the prop is just scraped real good not bent or nothing He thinks it was the rudder bend and turned way to the right i guess when i hit the buoy it got caught in the prop and that rudder bent and turned it but i just came back from the pond is running beautiful no problems TODAY!!! GOT RIGHT OUT OF THERE THOUGH 4-6 FT WATER THATS ALL i NEED

thanks for info
