My 95 GTS 587 is acting up! It runs great for about 5 minutes, then just dies. I can restart it no problem, but then it dies again in seconds. I have cleaned out the fuel valve which was full of gunk, but that did not fix it even though it flows great and turns easily now. Next I took off the carb and cleaned out the gunk from the inlet and outlet and cleaned the screen filter inside. That did not fix. Before I decide to put a rebuild kit in the carb, are there any other ideas???

lack of fuel or to much fuel? how do the plugs look as soon as it dies? try very slightly choking it when it goes to die and see if it keeps running?

try cleaning the post and key, and checking connections........sounds like electrical
OK, it could be electrical, but it is consistent that it cuts off after 4-5 minutes, then can restart, but runs only seconds. If I let it sit for 15 minutes, it will run for 1-2 minutes again. Is there a overheat cut off sensor? It does not seem hot ( I can touch the block) but could something be malfunctioning in electrical that consistently? Thanks for your help

dude, dont start another thread, on same topic. We told you things to chase. You have fuel problem. Reason its running 4-5 minutes, is because the fuel lines are fuel, then they run out, hence motor quit. Then after 15-20 minutes of crank'n, its "refueling" the system again.
Tear the carbs out, stud..and go thru them...:cheers:, along with entire fuel system...fuel selector, inline filter, and pull the baffle out of tank, and inspect the hoses in there. They're probably laying, down inside tank.

I didn't know the full story, now I do......
OK, so I spent all day and rebuilt the carb. It actually looked very clean inside. No gunk build up in the filter or any other passages. I replaced all the gaskets, etc., reset the low and high speed valves and re-installed. This was after they sold me the wrong rebuild kit and I had to take it back and go to another store to get the 38mm one. Unfortunately the problem is still there!!! Sorry to have started a thread on the electrical. I thought maybe that was another problem. Anyway, I tried disconnecting the temp sensor and no change. I also tried grounding it and got the buzzer, so it appears to be working OK. I have cleaned all the fuel lines and the switch and the fuel tank pickups and inline filter. It still has the same symptom. Will start and run well for 4-5 minutes, then just dies no matter what speed I am running. Thereafter, it just starts and dies in 1-2 seconds. Made it back to the dock totally frustrated!! Any other clues??

you remember what color spring was in the n/s assy?

replace the o-ring inside the inline filter, or just get a new "inline" filter...(lawnmower filter)
tighten all calmps on fuel lines and exhaust couplers, too.

if you remove the fuel selector valve and soak it in cleaner and I mean soak it for a period of about 20 minutes { continuous} and then blow it out.. about 3 beers for the time involved you should see more crap come out... then try it..... see if that works....... timmyboy is johnny on the spot on this stuff please heed his advise

just fixed a gts with similar problems. Found the o-ring that goes to the inline filter, under the gas tank. Well it was shot, so replaced the filter with clear tube one, you find for lawnmower..etc. Youd be surprised if lost/bad, what the o-ring will cause.
Whats the compression?

fuel valve
Last year one of my SPX skis did the very same thing you describe in your post. The only way I got it to run for more than 5 minutes was on reserve. I cleaned the fuel valve and it seemed to be working. (fuel flowing) only not enough. The rubber seal inside was worn and frayed. I bought a new fuel valve and presto!!! no more problem.
Hope this helps :cheers:

Thanks for the input. OK, so it sounds like the next is to re-check the selector switch and fuel filter. I have replaced the filter with a new one this spring and thoroughly soaked and cleaned out the selector switch, but will re-check. Could it be that I dissolved the internal seals in the selector switch by soaking it in carburetor cleaner??? Also, I am thinking I should replace all the fuel hose while I have this apart AGAIN!!. What about the reference to the exhaust coupler? I don't know what I am looking for there. What am I checking and where?? I have not checked compression since it runs strong when it runs. Thanks again for your help. I will get the stuff ready to tear it down Saturday.
I am having a very similar problem, let me know if the fuel selector valve is the cause. It would save me a lot of time. Well I will probably start there myself anyway. I have a 93 xp and it stalls about exactly the same time and way. It has good compression, 160 in both. I would prefer to only take off carbs if absolutely necessary.
I took mine out, looks spotless. blew out with compressor and has good flow, nothing flew out. Looks like it has been converted to black fuel hose in past. A few small holes in fuel filter though. Fuel lines did look varnished on the inside, pulled out some solidified varnish from the selector line, will replace fuel hose. I should probably pull the carb too, because anything loose probably ended up there.
Mine cuts out at full throttle it seems, or when getting on it.
Hope it's cool I am posting in this thread.

Yeah, that's what I think, too. I bought all the line and clamps. Probably won't get to replacing the lines until later this week. I hope this works! When I was moving it to the launch ramp, I tried hitting the start/stop button when it died and it restarted instantly. Did that several times on the way. That seems funny for a fuel problem doesn't it???

not really. It's get'n choked, then when off, it's able to "bleed" past the clog, to get you that firing up again,then it repeats itself. Just replaced a few skis' lines, and DAMN, whatta mess, especially in the selector and internal filter....that sh** gets everywhere.

My opinion is you are way over thinking this. If you haven't already, go to the auto parts store and get about 30ft of fuel line. Then go to the sea doo dealer and spend $25 smackaroos for a fuel selector valve. Then go home and enjoy the rest of your day replacing fuel lines...one at a time. Don't forget the short lines between the carbs.:cheers:

Part way through the fuel line replacement and going well. Found that the selector switch I cleaned with carb cleaner earlier was not sealing so I ordered a new one. Also found that the check valves hi and low were not working. High one leaked both ways. Low one was plugged both ways. So I ordered those too. All hoses replaced and awaiting the new parts to finish up the job and try it out!
