I have a 2002 GTX 4-TEC and generally like it. My only dislike is the OPAS (Off Power Assisted Steering) system. It tends to make the boat behave strangely at relatively slow speeds. It is quite easy to disable the system...which is what I did.

Hope this helps!

This year Sea-Doo is making the RXT and GTX Limited which are both 215hp 3 seaters. Both have enough power to do anything that you could possibly want, they are stable in rough water but still fast enough to beat almost any stock 2 seater on the market in a race. They are not cheap however, I have been doing my research as I am buying one or the other and prices start at $10.5k for the rxt and $12k for the ltd. Just curious Jetskier, which method of disabling the OPAs did you use? I am stuck between Riva and R&D.

You are correct! My bad. At 215 hp both of these are going to be very fast right out of the box. My guess is that they will push 70 mph and that is very fast on a PWC.

I looked at the Riva webpage and there appears to be two ways to do this. They show a block off kit to fill the void in the event that you completely remove the OPAS. This seems to cost on the order of about $300. The second method is to use a spacer. In this case the fin is held in the retracted position under all conditions. I originally used an aftermarket aluminum billet part that fell off. I then decided to make my own out of PVC tubing. I cut to the same length as the aftermarket part, filed a notch in the top and filed a groove around the waist of the part. I secured the spacer on the shaft with a cable tie. No problems so far! Riva seems to have a part for about $19.

prostar, the GTX 4-tec, without the supercharger, will go just a little bit faster than your old GTX (I have the 1999 GTX Limited). My buddy has one, and when we go head to head We stay right next to each other, and he very slowly pulls away from me. The 4-tec has plenty of power, and is very capable of pulling a skier or tuber. Of course the supercharged is a lot more powerful, but also a lot more expensive!
