Hi guys (heres a short story about my problem)

I have recently bought a GSX Rotax fuel injected Seadoo. Its been fine until today. I am riding and suddenly it has no power, it feels like the petrol line isnt pumping. Anyway, i slowly bring it back into shore, and take it home. I then change sparks plugs and take it out the next day..I am riding for about 20mins with no problems... and BAM!!! same problem,it has no power when i try to accelerate. I then bring it back to shore and test it on the trailer, It is fine!!! go figure, It did this to me three times. WHAT shoud I do???????? What is the problem?????? I am scared to take it out nymore because i have been poking and proding around. Please give me a tip on the problem..cheers

I have a GSX RFI with the same problem. Did you find the answer to your problem? Thanks John

I would remove the spark plugs, hold it WOT and crank it. If fuel comes out of the spark plug holes, it's getting fuel. Check the gap on the plugs. If the gap is too large, it can cause a similar problem. After getting service from my dealer, I took the ski out and it ran great for about 20 minutes then just started bogging down. Pulled the plugs to discover they were wet (with fuel). Got a new set of plugs, gapped them myself, and never had a problem again.
