SXR 800 Pump replace or repair

Looking for a solution for the pump issue of corrosion getting between the stainless sleeve and the pump housing. Anyone have experience with this? I would like to fix what I have or have it done if there is a good way to remove and replace the sleeve.

I’ve been looking for a replacement and have considered the Solas pump option Since I‘m having no luck finding a good used pump. Anyone use the Solas pump? If so are there any issues with the installation?

Used pumps: I keep seeing listings for pumps from various 750 models but the 800 has a different model number. What other pumps if any can be used for the SXR?
OEM parts are so expensive and everything is sold separately ,,,,,,,

What is the best solution? This is my primary ride and is only used in ocean surf.

I ran the Solas pump for a few years in our SXR, it worked great, less cavitation. Like any pump switch there’s always things you have to figure out, waterlines, nozzles, etc. but overall it was pretty easy.

You can recline a pump yourself if you’re savvy enough. I believe Atlantic Jet Sports sells replacement liners.
When I did it I used a small cutoff wheel on a dremel to add a slit in the sleeve, then worked it out. Clean all corrosion in the pump housing. Heat the pump and freeze the new liner and it dropped in. Typing it out made it sound simpler than it was, but it was totally doable and I did it in a couple hours.

I've replaced a few liners now on Kawi 750/800 pumps, just did a 650 pump as well. It's pretty straight forward. I bought 20 ton press just to do my SXR pump 5 years ago.

I have a 1990 TS, that sits in the water year round. I live on the backwaters of the Mississippi. After 4 years of sitting in water, the pump became quite brittle from the corrosion, so much I replaced the housing. This lead me down the road of ANODES!!

Long story short, even in "fresh water" your stuff can galvanic corrode. If you leave it sitting in water, put an anode on the pump! The aluminum pump housing is the least noble metal without an anode. I install anodes on my re-manned pumps now. You can get a ski doo one for $5. Cheap insurance.

I also put bearing retaining compound in between the sleeve and the pump housing. This will keep water from entering the area and leaving salts. You'll just have to heat the pump up to remove the liner next time ;)

Put a solas pump kit, with trim and their reduction nozzle in my sxr due too stock pump looking like a beaver got ahold of the stator veins. Got a smoking deal on it from the sketchy looking opentip website. The pump bolted right in. Only issue i had was the pro watercraft ride plate had an interference fit with the trim/reduction nozzle, nothing a little sanding didn't fix. Currently not running the downward trim, but if I was to run the trim, not sure if the pro watercraft plate would work without extreme modification.

I used to replace my Seadoo liners and grease the housing before inserting the liner but never thought of anodes. Great idea!

Find a good pump and seal the edges of wear ring.

Also a good idea and I have found what appears to be a good pump and plan to seal the edges of the liner When it arrives.
I still want to get the original pump rebuilt and Keep the other for a spare.

Thanks for all the response guys, I do appreciate the help.

I now have a pump that came from a 750 that I was told would work fine. I also have a New Solas KP-DF-13/22 from the Solas application chart. Now this is a large hub impeller and the pump looks like it’s made for a small hub. It seems to me that this would cause excessive exposure to water pressure on the front pump bearing and seal. Should I be using a small hub impeller instead?

what do people do when they use a 750 pump for a SXR?

I looked up impellers for a 750 Kawi and they all seem to have different part numbers starting with KE instead of KP. That may be the hub
size?

I have not taken the original pump off yet, plan to get it Monday and send it to Atlantic jet sports for re-lining.

The SXR 800 came stock with a big hub impeller. Making it a mixed flow pump not axial.
Click to expand...
Mixed flow and axial flow refer to the way the water enters and exits the pump, not the size of the impeller hub. Almost all watercraft jet pumps are axial flow , notable exceptions are the JS550 , WR500 and Kawasaki Ultra series, I won't go into it here follow the link if you want to know more.

As for the mismatch on the impeller and pump hub diameter you need to run an impeller that matches the hub size, it won't work correctly any other way .

I believe you. Thats what I was thinking too. Now I’m wondering if I need a different driveshaft as well. ?
Many people say the 750 and 800 pumps are the same, it's obvious to me now that they are not.
Now the impeller, should I go up a little from a stock 750 ? like The limited recommended pitch?
I usually just use what the solas chart recommends , I’ll probably talk with someone at Atlantic and Impros about it too before my next purchase.

thanks for your input



This is my first time taking the pump off a Kawasaki and the SXR is the only one I’ve owned. I have 2 now an 03 and 2010.
My experience is more with Seadoos that’s what I started with and worked on mostly my own for 20yrs. Now it’s mostly stand-up and the SXR is the perfect fit for me. I’m riding and wrenching a lot less now

I would defiantly talk to Impros about the impeller, they surely know a lot more than I do , I am just an old hack that has a lot of limited knowledge on a a vast array of watercraft related subjects.

You are very knowledgeable and I would like your opinion . What impeller would you suggest for this Stock SXR 800 engine and hull with the 750 small hub pump? I’m a recreational surf rider so top speed doesn’t matter
The info I could find says there’s only 5 hp difference between the 800 and 750 . I was thinking for surf riding the solas concord ke-cd-09/14 that is listed on their chart for the stock 750-SXI might be good . I have no experience with different combinations like this so I would appreciate opinions of those who do.

Look up the impeller reccomendation for an SXI PRO . that is as lose as you will get to an SXR.
