2001 seadoo gti 717 power loss

[Ajs]

So I was recently given a non running seadoo gti with the 717 motor in it. It had zero spark so after checking everything, I replaced the stator. Has spark now and even runs. Took it out on the water today and it seemed like it was down on power. It would top out at about 40 (not sure what they are supposed to do) and it would severely lose power while turning. It was also down on power from the start. If I started from a stop and gave it gas, it was like the boat needed to slowly build up power. Not sure if this could be impeller or wear ring or what. Any thoughts? When I got it on land I looked at the impeller and noticed heavy gauge Braided fishing line all tied up on the shaft. This line was probably an issue cause by the previous owner. If anyone has thoughts, I’d be happy to hear, thanks in advance

Sounds like you need a new wear ring. The specs are in the manual, you can check with a feeler gauge but it should be real tight

I forgot to mention this in my previous post, but the seadoo engine would start fine, but when I was running it, it would seem to “cough”. After about 20 minutes of riding it in the water (at around 30mph) I went to trailer it and it died as I was coming to the ramp. I couldn’t get it to fire up again and had to swim it the rest of the way in. I’m not sure what this could be and really appreciate any input

I may have given you the wrong advice, I was thinking that it was running correctly, but just lacking in power, I would follow the usual steps, check your compression first, check your spark which you say is good so usually if compression and spark is good, I would go over the fuel system, pressure test or change o ring in fuel filter, test and clean or change the selector valve, use good fuel line, and rebuild the carburetor with back to OEM kit from osdparts.com and follow Mikidymac’s carb rebuild thread

I began checking the fuel system. Lines look great and other than very small debris in the filter, they were clean. I will replace the filter. Tried pulling carb apart to clean and rebuild. Got it all taken apart except for the screw that holds the jets in. It looks like someone has been in this carb before and completely stripped out some of the screws. Ordered a new carb to put on within the next couple days. I’m hoping that this new carb will solve my issues since the ski has good compression and spark.
