The other day while backing off the trailer at the launch ramp I had an odd experience. It sounded like I sucked up someone's anchor line. After pulling the boat out of the water it appears my rudder had spun 180's and it was making contact with the prop.
My boat is a 2000 Malibu VLX. I have done what little research is available on this and here are the two scenarios I have heard of this happening:
One: The rudder's Keyway is damaged and it's still clamped down hard enough to steer but the rudder arm and rudder can be spun around due to excessive prop thrust (suction) when the boat is in reverse.
Two: Same as the above only the keyway is NOT damaged and this can happen at any time a person driving in reverse has the wheel locked in either direction. The thrust from the prop in reverse can "suck" the rudder beyond it's turning radius, twisting the steering cable in the process. In addition this scenario can happen on the "older boats" as their rudder boxes did not have positive stops in the rudder's range of motion.
Has anyone else had this happen and can you confirm or deny the second scenario as a truth or B.S.?
