93xp trying to verify rpm since my tach is not working. Hooked up a timing light and says around 6000. Do I cut that in half since it is a two stroke engine? This is out of the water, trying to make sure the rpms are high enough out of the water because it won't start in the water but starts...

Ok just to give some info, 93xp new starter, battery, all fuel lines, rebuilt carbs, new primer system and lines, and more. Starts in the garage and fires right up first try. Put it in the water today to test drive and won't start in the water. Had this problem last year when I put it in the...

Just bought a pump and impeller used. Disassembled to check bearings, change oil, and confirm impeller pitch, etc. The impeller has the last three numbers punched out! Does that mean it has been worked on? Or maybe the pitch has been changed? (You can still distiguish 182)The guy I bought it...

Just bought a new impeller and removed the pump to install new one. How can I align without the special seadoo alignment tool? Thanks.

Ok here is my problem, I bought this thing not running and got it running last summer only to find the impeller splines were stripped. As I am looking for a new one I find that the flywheel case has a tag that says 587 on it. Today when I picked up a new impeller from a guy he had a 587 and a...

I need a new impeller for my 93 xp. I found an entire pump and shaft from a 95 xp 717. According to the part number chart for impellers I found the 95 717 takes part number 458 and is 11/24. The 93 calls for part number 182 and is 11/26. If I put this unit on mine what will it do?

Ok I need a new impeller for my 93xp. The splines are gone causing a no forward movement condition. Anyway I have found a few possibilites on Craigslist. One is a Skat track impeller only that has 69 stamped on it. The other is a pump from a 97 and is part number 271000497 11/22 pitch. Mine...

I need an impeller for a 93xp with the 587. I also need a wear ring so basically a jet pump. What years/models have swappable parts for this? Please PM for a response. Thanks, Tom

Have found someone close by parting out a 97spx 787 and was wondering if the pump would be the same as my 93 xp 587? I assume the impeller is part of the pump?

So I am going to replace the oring on the impeller shaft with a c clip to fix the problem of no movement and overheating. I spoke with the guy I am buying the clip from and he said I don't need to remove the nozzle and pump parts on the outside of the ski I can just slide the boot/rubber piece...

Finally got it in the water and would'nt move at all. Revved it at all different rpm's and no movement at all. Finally the buzzer went off telling me it is over heating. Shouldn't it not over heat if in the water? I assume the wear ring is shot? But I thought I would get some movement even if...

I rebuilt the carbs on my 93 xp with Winderosa kits. The only way it will start is with the throttle held wide open and takes about 30 seconds. I have read that the buttons on the diaphrams are too tall and cause the needle to leak and flood the engine? If this is what is causing my problem then...

93xp I pulled the hose adapter off the head yesterday to prepare to finally put this thing in the water and found some sort of mud/plant type crud in the nipple. I am trying to clean it out. My concern is that maybe this stuff in through the whole engine. How would I clean it out? I would...

Just shopping where is the best place to get a wear ring? Are aftermarket ones decent. Also I have seen some stainless steel ones, are these good or bad? I guess if the impeller hits it your done, but if not it would hold up longer?

93 xp finally running but backfires when trying to rev up sitting in the garage. Rebuilt carbs, replaced lines, everything else. What causes backfire? I want to get this resolved before I put it in the water with the seat on.

OK I made a degree wheel and the RV is correct. I did the solder clearance method per the seadoo manual and using the .032 solder my clearance came out to be .017 which according to the manual if I read it right I am .003 too big. So the manual says it could cause hard starting, and the RV...

Ok back again, 93 xp 587 I have rebuilt carbs, replace fuel lines, cleaned all assoc. fuel components. I have 140 psi compression and good spark. Got it to run for a few minutes then sputtered and died and won't fire again. Was talking to a small engine repair shop today and the guy said that...

Ok rebuilt both carbs replaced all fuel lines, cleaned out filters and selector valve. It will start with a squirt of brake clean then die. Replaced plugs with new NGK's BR8ES and fresh fuel. I have fuel pumping into carb out to the second carb but none to the return line. Is this normal? The...

I have a major vacuum leak on my 94xp and read on another site about someone exchanging thier rotary valve cover for another from SBT? Do these go bad or leak? Just trying to find my vacuum leak.

Ok I am narrowing this problem down, I think. When I choke both carbs with air filter covers it will idle but rough. Then it will go all the way up to 7k rpm and stay there till I shut it off. All my lines are tight, where can it be leaking from? I had to remove the intake and rotary valve...
