These early skis were never designed to accept fuel that has ethanol in it. The result is that the fuel lines look fine on the outside but on the insides of the fuel line they are falling apart sending debris into the carbs or injectors and fuel petcock. Replace all fuel lines, clean injectors or rebuild and clean carbs and petcock and replace fuel filters.
I agree with sac rat. Easy to replace the fuel filter and check though. I was going to say possibly pickup screens but you covered that. You may have fixed it already.
No it didn't, but my Yamaha filled with water. The way I diagnosed it was putting it back on the water and just puttering around the dock until I found where the water was getting in. Probably the most common leak on a Seadoo is where the drive shaft enters the hull at the support ring and carbon ring.
I wont trust the wife 🤪 check your wear ring or replace it is easy to do and give you peace of mine. If that dont fix it, take the carb out again, start fresh do a rebuild, replace fuel filter, hoses and you be water ready, also notice you still have some old gray hoses, replaces those asap they clogged easy.
How did you remove the fuel pump assembly? I have the same model seadoo, but the pump assembly hits the top of the hull with 1-2” of pump still in the tank. I’ve tried pulling it out at different angles and twisting the pump to different positions. Did you remove the top black plastic piece from the aluminum body on the pump? Did you have to move the tank at all?
I had the same issue and no, I didn't remove the top of the pump. I moved the air ducts, drained the tank to almost empty and slid the tank forward. I got it out but I still struggled and it wasn't easy. If I ever have to do it again I'm going to take the extra time and remove the plastic housing of the ski above the tank. I believe that would give me easy access to the pump. Good luck.
@@papadonjetski9535 Easiest way on those is just pop the steering cable off. Then remove the 4 bolts holding the steering support assembly to the hull. Then just raise the steering up off the hull for the extra clearance you need to pull that pump module out.
@@anthernandez6014 I think I found them on Amazon for less than $15. It is hard to believe that fuel filters were the issue, but it ran great after changing them.
It did, and it ran great until last fall when it again lost power. This time, it is something different. I currently have the fuel injectors out to clean. Hoping they are the problem now so I don't have to keep searching.
You can go to a website like Partzilla (there are others just like it) and there it will walk you through finding your 94 Kawasaki parts diagram. Once you find the propeller, it will list the part number on the right. Then google that part number and you should see multiple places that sell your propeller and you can do a price check between them.
Yes, I did a follow up video. The filters turned out to be my problem, got the ski on the water and it ran great. I've had it out on the water many times since this video and it still runs good.
Did you change the 2 filters? It worked for me. Another commenter said his ski was doing the same thing and it turned out to be a broken reed petal. Something else to check if you haven't already fixed it.
hello I have a gsx limited 99 951 carburetor and I have the same problem in the trailer it accelerates well but in the water it does not accelerate as if it drowned you know that it could be thank you very much
Well, it could be the same problem I had with the GSX. The problem was the 2 fuel filters on the bottom of the fuel pump assembly. You probably have the same pump so my video will show you how to replace them. Or you could have carbs that need rebuilt along with new fuel lines. My GTI ran great on the trailer, but on the water it would die as soon as I gave it throttle. The problem turned out to be dirty carbs and old fuel lines. Once I rebuilt the carbs and replaced the fuel lines the ski ran great.
@@papadonjetski9535 good my gsx limited does not use electric fuel pump does not use internal filters in the same way remove everything and repair the buoy, I already rebuilt the carburetors, change all the gasoline lines, cooling line, spark plugs, check the rev valves I don't know what more review. Thank you very much I am waiting for any other suggestion
@@rookiethomas That has got to be very frustrating. One question, when you rebuilt the carbs did you replace the needle, seat and spring? If you did replace the spring then your pop-off pressure could have changed. Another suggestion, check your reed valves. You said you checked the rave valves...right? Check your reed valves to see if any of the pedals are damaged.
@@papadonjetski9535 hello replace the guides, the needles and the springs check the pop off and it is at 20psi. They review the sheets and they were good, but I had to disassemble everything and review it again to clear up any doubts. The strange thing is that when I tried it twice, I accelerated well, but when I let go and accelerated again, it no longer accelerated.
Yeah, the 2 fuel filters I replaced in the video fixed it. It has been running great ever since. I did a follow-up video on it after taking it to the lake.
