Ive got a 91 Sunsation Rocket 24' with a built 454/500hp and Bravo1 with a HD Transom Assy... I just bought the boat a month ago, but have noticed the higher the speeds I run, the steering becomes very stiff / tight when trying to steer to the right only. At slower speeds it more balanced from right to left.

At the higher speeds, It seems to steer normal to the left normal though, and if I let off the wheel it'll start to creep the to left just a little bit.
But like I said, when really moving around 4000+ RPM, I really need to put effort into turning the boat to the right...

FWIW, there was a new steering helm and cable installed earlier this year along with the new transom assy...

Any ideas or what I should look for??
