    The thru hull fitting will work fine...RXT and GTX have the same hull. No one, to my knowledge, has tried the waterbox on an RXT/GTX. Personally I think it will fit fine because the distance from the j-pipe to the transom is the same on RXP/RXT/GTX, the riva flow-thru exhaust pipe is the same for rxp/rxt/gtx. How about you being the first and document your install...If for some reason it dosen't work you can always sell it and get what you have in it back out.

    I'm almost certain it would fit, but i would hate to sell you one and it not fit. Once all the back orders for the RXP water boxes are filled and an i have an extra one i will fit it to an RXT just to verify.

    The RXT and GTX hull are the same? If you could do that, it would be great! I just love the sound of that thing!

    I have an 2002 NA GTX, and this weekend at Norris Lake, it overheated and Melted the rubber insulator on the first waterbox, plus a sensor and maybe a couple other things.

    Anyway, I was wondering if any of these exhaust mods might fit an NA GTX?

    Any other options other than just replacing the expensive OEM parts?

    Thanks,

    Mike

    I know.

    Here's the whole story.

    I had my ski at a dealer/friend for a problem starting. He ran all kinds of tests, fuel pressure, ignition tests, etc, but never found any problems. He claims it was probably bad gas. He said they put around two hours on it during various tests.

    Anyway, picked up the ski on the way to Norris lake. Put ski in the water. Long idle out of the no wake zone, like a half mile or so. So far no known issues. Got up on plane and rode not more than a 1/4 mile. Engine started bogging and then threw a code. Pulled lanyard. Turned around to look under seat and saw smoke poring out from under seats. Popped the back seat, saw way too much smoke and made a hasty exit from ski. Swam a short distance away and watched. Smoke started to diminish, but not very fast. Got closer and splashed water into compartment and could hear sizzling when water hit the exhaust. Ski stopped smoking about 15 mins after it started. Climbed on board and looked, waterbox cover is seriously melted, sensor near waterbox disintegrated and fell out.

    Got a tow back to marina and trailered ski. Called dealer "friend." Song and dance about sucking up a piece of wood starts... Water was clear enough to see 15 feet down. I KNOW I didn't run over any debris.

    I tried pulling the hoses on top of the exhaust and blowing through them, none of them had any restrictions...

    Not sure what to try next. Maybe try running ski on the hose for very very short period and checking hoses?
