[DavidHaggar]

Hi all , my name is David , i have 3 weeks ago bought a 2004 GTX 185 with 124 hrs, i took it out today for the 2nd time . i was towing a tube for about 5 mins , then it lost power and sounded different . if i tryed to accerate it had massive vibrations and flet like a car does when the clutch is slipping. i no nothing about jet skies so have no idea what might be wrong , or when i can take it to get looked at , if some could help i would be really grateful .
Thanks in advance

Check your pump for debris. At first....I'd venture to say a plastic bag, leaves, a stick...something was injested by your pump.

Hi
most Rotax engine vibrations are due to it not firing correctly so it is either your spark plugs or a fuel issue
is it rough on idle or only when you give it some throttle
ie vibrate all time and icrase intensity with rpm
as you say ski has 130 +hrs on it has it been serviced ???


Suggestions

try putting some new plugs in easiest option first

fuel filter check if clear

(look under seadoospines sticky on the forum for checking the little fuel filter inside the fuel pump on the carbs

few weeks ago had the same issue with my 95 xp

pulled the carbs off removed pump cover and pulled out the filter and it was rammed with cr*p cleaned it and within 1/2 hr was back in business

so it will be hopefully an easy DIY fix and save you a trip to the dealers

let us know if you need more info or help

we are a great bunch here and everyone will do all they can to help you


and finally welcome to Seadoo forum

Welcome....

:agree: with both. They have given you good insight as to what you may be looking for. Troubleshooting in the dark is hard, so make sure you give as much info as you can, related to your problem. Also, give all info on the steps you've already taken to fix your problem.

Lastly, because this thread is already a "trobleshooting" thread, I'm going to move it to the proper category. If you'd like to do anohter welcome thread, please feel free to do so......:cheers:

Hi all , yhanks all very much for your prompt advice . i found a small piece of drift wood about the size of a bottle top stuck in one of the impeller blades , im not sure if that would be enough to cause the problems i was having , but now i have to wait till next weekend to put it in the water and try it .

and no it seems to idle ok and normal , with my limited knowledge i think the engine is ok .

thanks again , i test test it and let you no how it goes ,

Yes, that's all it takes to do what you described. With a very small stick caught in the impeller, you will lose almost all thrust and will vibrate a lot.
Check your wear ring for damage from the stick.

cool thanks Chester , that puts my mind at ease a bit , i just cant wait to get it in the water and test it ,


excuse my ignorance , what is the wear ring and where is it ?

thanks heaps

ware ring

Ok so what i understand from the ware ring is take a flash light and look inside the back of the ski where the water shoots out look at the impeller it sits in what they call the ware ring there should be 1mm/.040.measurement between the impeller and ware ring if there is more than that u should replace due to lack of power i think what he was saying is to check if the stick dammaged this due to the fact that it is made of rubber

Thanks heaps to everyone

cool thanks Kenny , found it .
It looks to be not too bad , i just had it in the water for 2 mins and it appeara to be fixed , woo hoo......
i am taken it out after work today for a real test , i will get my friend to tow me and see if it still has the power to oull me up from a deep water start on 1 ski , cant wait..........

Thanks to everyone that has helped me, with this problem , i am very suprised and amazed at what a gruop of people with the same interests will do for each other , even when we have not met . thanks again i hope one day i can return the favor .
ps , i will keep you all updated after this weekends full test

What a 1/4 inch gap between the wear ring and the impellar???

 

[pythonz281]

no on the 1/4 inch gap i read that somewhere and i found the right answer

the space should be no more than 1mm/.040. between the two

Sorry guys !

Rubber??????

Your correct on your measurements. It's best to have the impeller close enough to the impeller wear ring that you can barely see light around the edges. But the maximum amount of clearance is .040". When you get close to this tolerance limit, you'll notice a loss of power.

The easiest way to check it is to look from the suction side, into the impeller. If you can have someone with a flashlight shine in from the back of the nozzle, you can judge the tolerance. You'll find this easier as the years go by and you continue the maintenance on it your self.

The wearing rings vary in composition. You can purchase them in stainless, which I oppose, or you can by them stock. The stock models are very hard rubber with a teflon insert inside that is kind of like the bone structure holding the rubber rigid.

The reason I'm against the stainless rings is because the rings are meant to wear from abrasives like sand. Sand spinning out at the edges of the impeller hitting the wearing ring is slowed greatly as it bounces off the ring. This minimizes the sandpaper affect on the rest of the pump and nozzle.

I know a lot of users like their stainless wearing rings, it's just my personal experience with the type I use and experience with sand blasting equipment.:cheers:
