RXT-X taking on water after mods !
i have just fitted riva stage 1 kit to my RXT-x & took it for a test, at first it ran 8040 revs at 71.1 mph, it then threw me doing a slalom & starting cavitating (i think), i crawled to land to find the hull full with water 1\2 way up the engine mounts, took about 5 mins to drain & then it ran at 7940 revs at 71.1mph & after only 2 runs it died again cavitating as before, when i removed from water this time i noticed water was pouring out of where the drive shaft goes into the hull like a tap & was again full of water,
does this sound like the carbon seal has gone & do you think fitting the stainless ring & new impeller could have caused this, my ski has only 20 hours on the clock, also how do you check if it has gone on an RXT-X,
any ideas guys ?

I would vote on it being the carbon seal..If water is pooring in from there then it is more than likely toast..You shouldnt have any issues with taking on water just by putting in a new wear ring and prop..

20 hrs is pretty quick to burn up a carbon seal. Do you have a nose cone on your impeller? If so it could have come loose on the shaft. This can cause the carbon seal to leak. Alot of people including me do not run nose cones.

This is very interesting, just got a call from another T-X that was taken on water with 50 hours and appears to be thru the boot so must be carbon seal related.
What gives on this one?
Have you looked at boot to see if something is missing?
This ski also with mods and prop?

When I had my 07rxp new last year
the carbon seal started leaking at 3 hrs, I couldnt figure where all this salt residue was coming from after each ride.
Then one day left the ski sit for a couple of hrs and found 6'' in the hull.

BOy, wouldn;t you think that BRP would recommend changing the seal at 100 hours? Maybe they know that they will make more money with water ingestion if they don't... Ron

Considering the x models have stage 3 power from stock, seems the stock carbon seal isnt up to the job. It needs to be changed out with a aftermarket one to cope with the extra hp..
