Hi, I was wondering if anyone out there has a solution to my problem. I have a 2001 prostar190, that does not track very well while pulling a skier through the course.Has anyone out there had the same problem . If so is there any way it can be fixed ?

A dealer says all I have to do is have the rudder filed to cause the boat to pull one way more. Does that sound right?

The back end just seems loose.

Have you ground down the rudder at all? This causes a slight imbalance in the amount of lift of the rudder thus requiring the driver to add torque to the wheel to counter the rudder torque. This "loading" the rudder will help the boat to track well.

Not to question your abilities but do you have much experience pulling someone in a slalom course? It is somewhat different than trying to pull someone in open water.

Theres nothing wrong with rudder or shaft.

possible...there is an edge on the rudder. How much does it drift from course start to finish...

The "loose" feeling that he described is caused by the dead spot that the rudder has on center at speed...he has nothing wrong with the steering or shaft.
It is a common feeling on a boat that has not had a rudder ground.

I have not done anything yet, but I think your on the right track. I just bought the boat off of my brother .My buddy and I only used it in the course once last summer. We were not to impressed with the tracking . I have 25 to 30 years of experience driving and skiing through a course. I was very surprised that this boats tracking was so poor.

Yes, grinding the rudder is not a hard task...but its not one that you want to mess up. If you grind too much you will end up having to replace the rudder.

Have you checked your scags, or shark fins? If their not straight then you will also have tracking issues... My brother had one bent and his boat kept pulling to the right.
