Has anyone else ever noticed thier prostar leaning or listing to the right??
Last night I gave it a tune-up, wires, plugs, oil change, etc..
We put it back in the water, and my wife was in the passenger seat, and I drove.
I eased the throttle to about 22mph (trick speed) and noticed it was "leaning" to the right!
My wife said it has always been that way. I've never noticed it before! We were driving straight! Anybody else????

Just a difference in weight between you and your wife. Those boats are very sensitive to weight balance because the boat is relatively light. You will notice a difference in the wake with as little as 20-30lbs difference side to side. Also prop rotation (right hand or clockwise) has a tendency to make the difference a little more pronounced. No big deal. Load the gear on her side to even it if you like but nothing to worry about.

1990 prostar: also leaning a bit to the right if I drive by myself.

You could be right! I brought my tool box along and placed it behind the drivers seat as well.
I didn't think of that until just now. I do weigh about 195 and she is 110 soaking wet!
I was just courious if anyone else noticed this?

Its normal, like BrianM said. All about ballast. I notice it with my 197 as well, thats why my board racks are on the passenger side, even it out.

I'm thinking it was just my toolbox, trick skis, Wakeboard all of which were behind me!

Thanks! It's still under renovation, but we can't stop skiing long enough for any real work to get done on her!

I made up a couple of canvas ballast bags that I filled with old tire weights. The bags are about 50lbs a piece. We ski a lot with just a driver and throw the bags in as far to one side as possible. I have found if you set the bags up under the combing pads the 100 lbs is enough to completely even out the wake.

As said above even the new 197s do it which is why MC offers the MTS system which is just an integrated ballast on the passengers side.

I have a 60# sandbag along the gunwall behind the oberservers seat in my 1990. 2 would be better, but it helps. When the boat leans to one side, it makes the ski wake really rampy on that side.

I had the same boat and the white dash reflected up into the windshield on bright sunny days. I had to keep a black towel under the windshield. Still a nice boat.

My 96 prostar "leans" to the right too even when the weight in the boat is evened out. I think its the right hand prop rotation that does it.

Change the prop rotation to RHH. It'll back up funny, but will not lean with just the driver when underway.

The old Stars and Stripes does the gansta lean when I take her out for a cruise on my own so I usually put the craftsman tool box on the far passenger side in front of the bench so it evens it out with the extra weight and the battery being on that side too.

Its normal.

I'd be happy if I could get it to back up straight

I know of one person who can do that. I'm not that person.

These boats are "tender" i.e. sensitive to weight placement. A LH prop makes the boat list to the right. My SkiPro I/O with a RH prop lists to the left, although it's not as pronounced as the MC.

My TriStar has the battery mounted at the transom, right in the middle. I was thinking of moving it to the portside corner to even things out.
