Weird Noise 2009 Seadoo 130GTi

[kazanka101]

Hello,

The last time I took my jetskis out it started making an extremely weird whining sound. It still had power, didn't seem as much but also seemed as if the RPMs were higher than normal. I haven't yet taken anything apart but I wanted to see if anyone could narrow down what the possible suspects could be. I don't think it's an engine problem, at least doesn't sound like it. Sounds like it could be the impeller, shaft or bearings? Has anyone had a similar issue?

Bad pump bearings. If it gets bad enough, it can cause engine damage.

 

[nfdmedic]

I agree, replace the bearings and see if that resolves the issue

 

[kazanka101]

So I took the back jet a part. The cone definitely looks bad and is most likely the problem. I included pictures below. I wasn't able to get the impeller off though. I do use the jetski in the salt water. I bought it used with 108 hours and now it sits at 160 hours. I'm new to taking them a part. I watched a few youtube videos and then tried myself. I'm guessing the impeller is so badly corroded its stuck on there? Am I missing something? It's an 2009 Seadoo GTI 130.

You must remove the entire pump to replace the bearings and it requires a few special tools...

 

[kazanka101]

Yes, I understand that but the pump is stuck and I can't get it off the Jetski. Is there a puller type of tool to get the pump manifold off of the jetski? The 4 bolts holding it on are removed. I believe it's heavily corroded as videos I've watched it seems to just come off. I'm certain this has never been done at all.

I followed this video -

It seems this guy has a tube that I don't have but everything else was the same.

 

[nfdmedic]

were you able to get the pump off? The shaft could be rusted in really well if its never been off and you ride in salt water.

 

[kazanka101]

Yes, I ended up taking to a local Seadoo mechanic and they removed it for me. It was really stuck on but everything came off. I'm just waiting on the new parts. I decided to replace the entire pump and impeller. Ordered all the parts I needed and now I'm just waiting for it all to arrive so I can put it back together. Costly fix but in the future I know about this and will just check it out each winter to make sure its good for the following year.

I ended up going with the OEM impeller. I was looking at the Solas but reading reviews of some people had me worried that it would break and do more harm than good. What're your guys thoughts on those? What do you recommend?

I'm assuming this will solve my problem...Fingers crossed.

2009-2010 had a special drive shaft that has a rubber coating with a screw-on floating ring. Part of the coating came apart on mine and got logged in the impeller. I needed a new carbon seal anyway so had the mechanic replace the entire driveshaft with a newer model. Good thing because he could get the screw on floating ring off so had to cut the driveshaft to get it out. I needed a new wear ring also.

 

[kazanka101]

@gpounders, this is what the inside of mine looks like. The drive shaft doesn't seem to have any issues.

 

[gpounders]

@kazanka101 looks like you have the rubber coating like mine. Here is a picture of the shaft they had to cut out of mine. To replace the carbon seal you need to order that screw-on floating ring and since they don't make those anymore that part alone is near $90 so I opted for full driveshaft kit from SBT even before trying to remove because I read that it's very difficult to get those unscrewed after 11 years in my case. He had to align the engine also. Out the door, it was $1300. New bearings, floating ring, carbon seal, bellows, shaft, and wear ring and 8 hrs of labor.

How many hours do you have on the ski? Mine had 240, I am the second owner and the mechanic thinks that was the original carbon seal but the wear ring was replaced before.

 

[kazanka101]

@gpounders My wear ring wasn't as bad as I had thought it was. I only have about 160 hours. I am also the second owner. In my case no maintenance was ever done and the person I purchased it from had his own dock. The only thing that I did to it was a standard oil change when I got it and every year since. I started having this weird noise come from it the last time I took it out and I believe the sound is coming from the bearings being bad, given when I took the nose cone off it had salt water in it. I did also take the pump off and spin it.


My impeller doesn't even look bad from the picture but I wanted to replace it anyhow.

I looked up the SBT Driveshaft you mentioned... Sea-Doo Driveshaft Kit GTI 130 Rental /GTI 130 /GTI SE 130 /GTI SE 155 /GTX 155 /Wake 155

Was this it? I will have to keep it in mind and might end up doing it sooner rather than later.

What happened with yours? It sounds like the rubber/plastic came off and got into your impeller?

 

[gpounders]

@kazanka101 yes that is the kit plus a seadoo bellow. Yes part of the rubber came off and lodged in the impeller. Just remember when you have to replace the carbon ring you might need this kit because the screw on floating ring may not come off. Most likely that is due as they only last 100-150 hrs. Mine was over due

@gpounders

I was looking more and more into this and it could even potentially be my problem. Given I figure if it did start to happen I wouldn't have any power which I still did. Definitely going to look into doing this maybe during the winter. Currently the mechanic I took it to was booked for 3 or 4 weeks out. He was able to assist on taking off the pump but I told him I could take care of the rest. Yet the driveshaft will certainly require more tools that I don't have. Appreciate the advice with the drive shaft and making me aware.

The pump alone seems to be a costly fix currently running me about $1k. I got the ski about 5 years ago for about 4x that amount. I assume these maintenance's don't come up much as long as you take care of it though.

 

[gpounders]

@kazanka101 I thought I needed new bearings in pump also but mechanic said they were ok. Noise could have come from small rock still lodged in impeller. He straighten the edges and sharped as much as possible and with the new wear ring the ski feels so much better on the turns, no move cavitation and blow outs. Hole shots and top speed also improved by 2-3 mph. I see the pictures looks like water did get into your pump bearings. My ski is fresh water only. As long as you have no leaks at carbon seal, then ride on.

 

[kazanka101]

Do any of you use Sea-Doo Parts & Accessories | Sea-Doo Parts House for getting parts for your jetski? How long do they normally take to process your order? I've tried calling them and haven't been able to get an answer or a call back.

I ordered parts so I can put my jetski back together but I ordered them almost 2 weeks ago today and still processing...

 

[nfdmedic]

i like partzilla but they often have to order the parts to ship to you. It is usually cheaper there but you will have to wait longer to get the part. Not bad in the winter when fixing but summer seems to take forever! If I need something quick I usually hit up a local dealer, they can usually have parts in 2 days

 

[gpounders]

My mechanic recommended the original Seadoo parts for the floating ring, carbon seal and bellows. The newer floating ring is wider and thicker so it seals better and lasts longer.

 

[kazanka101]

Apologies for the late update. I did get this all put back together and working again. @gpounders I did notice some of the plastic/ruber cracking from the drive shaft. Yet I'm thinking about waiting for the winter to do that as it's almost the end of summer and I've barely been able to use my skis.

Everything appears to work great. I feel as if the ski actually sounds a little bit different. RPMs are practically the same. I didn't use anything after-market.

When removing the old jetpump and putting on a vice I tried to spin it. It was definitely stuck but once I got it moving it was good. Definitely was the bearings.

The bad part is I took it out a day after and it worked fantastic and then the following day I took it out again and all of a sudden lost power right out of the inlet. I got it back to the dock and looked at it and everything seemed to be working good. I was about to take it all apart again but right before I crawled up under and it appears it sucked up a starbucks bottle and that was the cause of my problem... The bottle never made it through the jetpump but it was enough to make it seem as if there was no power. I looked prior at the dock and never saw anything but I'm wondering when driving it knocked it loose.

Anyhow everything is back in working order and it's running great! Thank you guys for pointing me in the right direction with this.

@gpounders

Funny thing... I put both jetskis in for the first time yesterday and it looks like that rubber on the drift shaft is coming off just like you were saying.

I ended up cutting a bunch of it off so it can still be driven but I plan to get the parts to do it. You had a mechanic do yours I was curious if there was any instructions on it at all? I heard you might need an engine alignment kit yet I don't have any movement in my engine and all the mounts look solid. Wouldn't it be a 1 for 1 replacement then? Obviously replacing with the 2011 drive shaft as the 09-10 are defective.

I also noticed water in the engine compartment. Not a lot though. Drove it around for about 2 hours and probably got about 2 or 3 cups full of water out. I'm assuming this is the carbon seal that lasts 100-150 hours you were talking about?

Do you by chance have the list of parts besides the SBT Driveshaft? I looked up ( https://www.seadoopartshouse.com/oemparts/a/sea/500d5dd7f870020908257794/propulsion ) and it appears some of those parts you can't buy. Should I be looking at the 2011 diagram and ordering those? Just don't want to buy the wrong items you know.

 

[gpounders]

Just by the parts for a 2011 model or this kit https://www.shopsbt.com/jetski/sea-doo-driveshaft-gti-gts-pro-130-155-rental-se.html

This gives you the carbon ring but you will need a new boot also which doesn't come with the kit. Just order the 2011 boot. The mechanic aligned the engine be he was doing all that work and had the tools. If yours is fine, then don't worry about that. You should replace the wear ring while you have it all apart.

Just be aware, you might need to cut the old driveshaft to get out if you can't unscrew it. That was another fault of the design. Good luck. With the new wear ring mine runs great, increased the top speed by 2mph

If you are only getting 2-3 cups of water per outing, I think you are safe to use it until fixed. The only risk is if more rubber comes off and gets in the prop.

 

[kazanka101]

@gpounders

So I ended up doing this... In your previous post and several others they all said to use the OEM for seals because aftermarket sometimes arent perfect fit which can cause leaks. What 'boot' part are you talking about? Looking at the diagram for the 2011 I'm thinking you're talking about #30 'Bellows' but unsure.

SBT shaft
OEM carbon seal kit
OEM bellow with bearing seal

At given its a watercraft and I'm using in salt water, I don't want the risk of something happening and causing more damage. It's been rough out recently so I figure I'm just going to wait until I get the parts. I did pull a lot of the loose rubber off but still can't get to all of it and the remaining pieces are closer to the engine.

here are a few pictures of it all currently including before I pulled the rubber off.

 

[kazanka101]

Got it all done. Haven't had it on the water yet but it definitely seems to be running smoother. By smoother...it sounds healthier.
