Left turn syndrome

Hello everyone, got my 01 xlt1200 ski out and today running great, but I've noticed I have no safe control in my left turns and read a little about it being called "left turn syndrome" it worked last year until my main drive line bearing went out and ended up replacing plus the shaft. The jet nozzle are equally moved from left to right, etc. Does anyone know why this maybe happening and possibly fix?

Thanks

Unsafe, meaning at high speed, I have little to no control with negotiating left turns! this is also at very slow speeds.
Last year I had my main drive bearing go out and I replaced it and another pluse a main drive shaft, used my same stock impeller.
since I had the exhaust out having to move the engine forward to get the midshaft and main bearing out to replace, I know my carbs needed to be reworked. I rebuilt the carbs and got it back in the water with 100% full thrust fwd and to the right (plenty of power)! if I turn to the left it takes pretty much takes the whole lake to turn! "very unsafe! I thought it maybe the nozzle but checked it and right and left are to specs (24)

I don't understand why I have ample power fwd and right but not left. Ive read that the engine torque/pump load, etc has an effect to this phenomenon but I never had the problem before. Seems like it had to be something going on with the pump system. I may pull it and look closer at all the specs.
Sorry so long!!

Make sure the nozzel is centered when the bars are centered. Ive helped with this before but its been a while. Let me do some searching. Could be the cable is frayed internally and compressing. Also check for excess play.

Thanks rodsatheart,

The nozzle is fully functional to the bars. 24 right and left as in the specs. the only thing I haven't checked is the impeller to wear ring clearance.
as of yesterday, I finally removed the wear ring housing (after snapping one bolt) never had it off. I took measurements and its out of spec on the bottom 1/3 of the ring. I don't know what else it can be. I can replace the wear ring with a new one and go from there.

I don't think there is any way the wear ring could cause your issue. But here is a great price on an OEM replacement. $122. (See print from riva)
If you can't get the broken bolt out. serch eBay by the part # for a used transom plate. Lots of them out there. I Broke 3 on one earlier this year after weeks of soaking and heating.(saltwater ski) Reseal transom with 3m 5200 caulking.
Do you have the step plates/trim tabs on either side of the ride plate? If so is the right tight and up flush. Are they plastic and warped or flat? Or how about the front right corner of the ride plate is it below flush? Any drag on the right rear will make left turns difficult.
