Great write up, Would a symptom of a bad wear ring be: No top speed? My 06 GTI-se runs fine, smooth power delivery, reaches max RPM, but top speed is 28MPH, where last year this was a 50MPH ski. I had a rag caught up in the impeller, and after some bad vibrations, I pulled all that I could find out of the exit jet, but after that, I get no top speed out of the ski, motor runs and revs fine. Almost like an slipping transmission in a car. Any help would be appreciated.

Lionking, sounds like a bad wear ring.
motor runs fine, and revs right up, but no thrust...

HI to all,
I have an Explorer. I think the pump is the same as the one in the article. I got the pump off and that took some doing since the studs were corroded to the housing. The wear ring is hard against the impeller from the same corrosion. I know I need a removal tool so my first question is where to get one. Suggestions? My second question is how will I remove the impeller if I cant turn it? It is so stuck and I dont want to damage anything. The third question is once it is out should I sand or use a wire brush on a drill to clean up the inside? The last question is once it is clean is there a good way to coat the pump so it wont corrode again?
Thanks in advance.

I have followed the instructions exactly and they have been very helpful, but my problem is when I pulled the pump I noticed that there is no boot on the driveshaft at the impeller end. When I pulled the pump the driveshaft remained sticking out of the hull end. As I have never seen one before can you tell me if the boot somehow inserts into the impeller and then the driveshaft goes thru the boot? I also keep hearing something about a carbon ring, where is the carbon ring located? Thanks, Steve

I have a 2009 speedster 150 255hp SC.... Took off my pump and can't seem to find anywhere online a spline/impeller removal tool! Would it work to put it back on the drive shaft put the boat in gear and crank on the 12mm allen wrench?

Nope... all you will do is turn the engine. AND... if you try to hold the driveshaft... you could bend it. So, it's not advised.
Here's your tool

Thanks... So even though this is a solas tool.. it works for the factory part? So when I receive this tool.. use my 12mm to hold where I removed the cone and turn the impeller tool counter clockwise? Right?

check out sbt they have removal tools for your impeller
Depending on your model, between 35-60 psi, and upwards of 90, depending on who you ask. Impros suggest 90 on their new stainless impellers.
I usually just tighten mine up with red loctite. Shaft spins opposite of threads, so it won't back off. Just make sure if your doing the older, 2 stroke pumps, you don't pin the thrust washer under the shaft. There is a lip on the shaft that can catch that washer. When you tighten the shaft, before you put your nose cone on, push the shaft in and out against the pump. There should be about 1/4" of play. It should also spin freely. If its tight and the impeller isn't hitting the ring, check your thrust washer....... If this is a 4-TEC, disreguard.

2004 Seadoo Utopia 185 Merc 240 EFI
Thanks Dr. Honda for the info.
Does anyone have an opinion on replaceing the liner (Sleeve) with a stainless wear ring and are they available for a 2004 Utopia 185 with a merc 240 EFI? Looks like both impeller and sleeve need to be replaced, I believe I will go with a Skat trac swirl and I think i would like to replace the sleeve with a stainless unit if it is available.
Can someone confirm the above procedure is the one for my boat and what parts are required to be replaced other than impeller and sleeve, I.E. seals and gaskets?
Thank you in advance,
Tim

The Merc boats are a totally different animal. They don't have a "Wear ring". They have a mid housing that is sacrificial. BUT... it's a $450 "Sacrificial" part. (in my book that's nuts) A seadoo ring is only about $45~$50
Normally, I don't recommend a stainless ring for a seadoo, since they don't do much for the performance, and they wear the impeller, and bearings quicker.
On the Merc boats... you dont' have a choice. It's either $450 for a new housing, or $450 for ImPros to install a stainless ring in your housing. Either way... it's hard on the impeller... but the stainless ring will continue to live.
Finally... as far as I know... the only aftermarket impeller for the Merc boats is from Solas. Merc makes a few diffident impellers... but they are all crazy expensive.

Thanks for the perspective
Thank you Dr. Honda
I was suspecting something was not rite but when I read the above post it stated All Seadoo boats so we should change that to all Seadoo boats with a seadoo engine and Pump. For you suckers with the Mercury stuff dig deep and take a deep breath if this has to be done.
Seriously thank you for the update, I felt mine was different just did not want to ask a question that appeared to be clearly stated ALL Seadoo boats and get flamed my very first post.
In you opinion am I better to have IMpros install a sleeve or purchase a new one. My dealer was $550.00 for a new one plus taxes and the impeller was 500.00 that is why I was looking at Skat trac and Solas.
I was noticing that the insulation all arond the engine compartment is deteriorating and needs replacing can you recommend where to get it. I was told I can purhase it in a sheet and cut to size.

Yeah Hoo, you got to pay to play, Good thing I cant play everyday Id be broke!
Okay, I need a little help. I have replaced my wear ring and put everything back together. I noticed that there were no shims on the unit when I pulled it all apart,but now that it is all together it is having a hard time turning over (enough that it wont start). What do you all suggest I do at this point?

Found a better tool to remove the wear ring.
I was at the lake yesterday and discovered I needed a new wear ring. No surprise, so when I got home I removed the pump and I was ready to cut out the old wear ring with the Saw Zall. Well I don't know why but I tried another tool that I had recently purchased from our friends at Harbor Freight.
The tool worked great, it went through the old wear ring like (as they say in NY) butter. I think I bought the tool when in was on sale for less than $20.00. Anyway it's much easier and safer than the saw zall.
