Hi! I’m having this same issue on the same boat. How did you fix it? I’ve took it to a shop, and they’re at a loss and said they won’t touch it because it’s a liability. It has the second rudder in the front (the mechanic had never seen before. he thought it was added by a previous owner) the front and back rudder are turning the same way, and he thinks that’s the problem. The boat when driving in the water turns itself violently to the right no matter how fast I’m going. The first time it did it it bout threw us all out.
