gtx 155 2010 help please

[AzurA]

my seadoo is taking in water lately
i thought it was a one time thing so i payed more attention to it lately and it took only a hour at the beach to get plenty of water in there , enough so i feel the weight when riding
i drained it yesterday, filled it with a hose to check for holes and leaks, nothing
so i did some reading online and noticed this mostly happens because of a worn carbon seal ?

so i have 2 questions please
1. parts here in israel are very pricy, about twice as much than in the states for a example, sometimes more, so i need to make sure its the part that is faulty before i order, so how can i tell if that is the problem for sure ?
2. is there a video that guides through the process of changing it? last year i took the prop out to change the wear ring, so i remember more or less but a video or a scheme would help
thanks in advance ppl

Have you checked the two plastic bolts above the jet pack? One is where the reverse shaft comes out to raise and lower the bucket and the other to the right. My 07 had a leak from there. If the 2010 is the same, it might be the problem. If there is a small separation, the water can get in there when it is stopped in the water. It was an $8 plastic bolt... There was also a clamp on the exhaust housing all the way on the bottom toward the back where it went from metal to hose. It is really hard to see, but if loose or corroded, can cause a leak...

could u please take a picture or something , im not sure what it is your referring to, its hard to look in my hull, i think i need to take the air filter out since its so huge i cant see anything :/

You can kind of cheat a bit on the Carbon Seal. Loosen the boot that is clamped onto the boat. Force the part you just I clamped closer to the Carbon Seal and tighten the clamp back down. Then take a zip tie and out it in the gap you just created by moving the boot. The tie will stop the boot from sliding back due to the extra pressure that is now on the boot. Take it for a ride and see if it quits or improves.

Unable to upload the pic that I took but I second checking the seals at the back where the bucket arm goes into the ski.

Replacing the carbon seal is not for the inexperienced mechanic. It takes specialized tools and some force. You've got to remove the pump, drive shaft, etc.

I sold my ski's, so I can't take a picture. However, if you are looking at the back of the ski, from the outside (if it is the same design as mine was), there is a metal arm that moves the bucket up and down when you go from reverse to forward. That arm goes through a plastic bolt. If that bolts starts to fail, water can get in when your ski is stopped in the water. If so, when in the water, you may see a the water dripping in. That is what happened to mine. My mechanic switched it out with a stronger bolt and it solved the problem.

i got it in the water now
went to check if i can see where the water are getting in
checked that place where the bucket are goes in, no water getting in from there
i held the ski in the water for about 20 min and couldnt find any place where water get into
my mistake was that it wasnt completely dry,so there was a little water in there and it didnt look like the water level is going up,although its hard to determine that this way.
next time i will soak every drop of water in there so i can be sure water are getting in when its "dead in the water" and not while riding
but just so i can keep exploring the problem, lets say the water dont get in when its parked, only when riding, does that mean its the carbon seal for sure ?

That would be my guess. But make sure all of our hoses and clamps are connected properly. To be sure, have it running in "neutral" with the seat off and check for a leak or spray at the seal. It should be visible, especially if you tie it securely to the dock and rev it.

 

[AzurA]

the thing is its very hard to see the seal
everything is so tight in there
i can reach with my hand and maybe feel a spray of water but seeing it from all sides is impossible :/

 

[Hacks]

Like 3ftdeep said, check the hoses. As I was fixing my problem I had noticed that the exhaust was lose and letting water in. So make sure thats real tight..

 

[3ftDeep]

I know it's hard, but you don't need to see clearly (there's a rubber flap covering the seal). All you need to do is confirm it's coming from that specific area. If it is, it's your seal.

As Hacks said, there is an exhaust hose that can spray water when you are riding the ski, my '08 had a loose metal clamp, the screw was tight, but the clamp was failing. Water can spray from there, hence the problem you describe. Check each and every clamp, not just the screw but see if you can move it with your hand. They should not move. That is an excellent suggestion! The faster you go, the more water will fill up inside the ski...

I forgot all about that. I would return and my '08 had water built up under the engine, but my '07 would be bone dry. That fixed the problem. I hope that helps, it would be a lot easier to fix than the carbon seal... There was also a metal pipe in the starboard rear that connected to a hose, more than a few inches in diameter. That clamp is impossible to see and get to, but I was warned that it could fail and if it does, it could sink your ski. You may need a light and a dental mirror to check that one out.

The joy of jet skiing! :thumbsup:

Loose exhaust can be the issue and will produce PLENTY of water. The Carbon Seal may leak when the engine is not running, but often not at all or very little. When the engine is on the seal can leak pretty bad if it is defective or a part that is connected to it fails.

SO, took it to the dealer
he changed the carbon seal
cost me about 300$
took it to the sea to check, rode it hard for about half and hour, hardly any water got it, gonna check it better on saturday
theres a small gap at the battery lid on the back that water does get in from there but nothing serious.

 

[3ftDeep]

$300 isn't too bad for the carbon seal. It's a bigger job than most people realize. Sounds like he charged 2 hrs labor, which is about right. If it has addressed the problem, it was worth it. Good luck!

 

[Spimothy Leary]

actually $300 isn't ridiculous at all, I think that was quite fair
