Be willing to bet it has something to do with your livewell. Almost every time, I have heard of something like this, it was because of livewell issues. I thought I was sinking a boat one time because water kept coming in, couldn't figure out what was going on until my buddy said his butt was getting wet! Turns out we didn't have the plug in the livewell that he was sitting on top of.
