Hey Pete, I saw that thread too. But our Toyotas (mine, at least) don't have any pull to the right. Not sure if this is different between the '99 (which I think you have) and my '01.
The pull that they are talking about is a hard pull, like if you let go of the steering wheel, the boat would start running in circles. The old Centurion we used to run around in did this pretty bad.
So anyway, I don't think our Toyotas "pull". I know mine doesn't.
