Problem has been solved and the boat steers like a dream ( Like it had for my first two years.) Bennington had gone above and beyond in everything they did. I was just simply caught in the middle, knowing their was a serious issue that was not normal in any way.
I actually drove around and took pictures of other Yamaha 90 hp engines from another dealerships with Rotary steering and then went into the dealership where I bought the boat. I showed them all the pictures with the tab in a totally different position and they were still insisting that the reason my tab was in that position was to try and correct the steering problem. I even asked them to bring a tech out so I could ask him that with the tab in that position, which direction would it make the boat turn. He said it would make it go to port ( left ) and they all once again said it was because of the rotary steering I had. I was LIVID. I finally said if they came to my boat, put the tab back to a 12:30-1:00 position and we went out on the water and if it did not fix the issue I would buy the upgraded helm. To their surprise, it fixed the issue and my boat was back to normal. Thank goodness! So glad to have my boat back and be able to enjoy it again AND finally feel like I wasn't a crazy woman. Thank you to everyone who helped me here on this forum and a huge shout out to Bennington. I am a customer for life.
