Rode my 2011 gti 130 se last Sunday with no problems. Today my jetski had a weird vibration and tops out between 35-40 mph. When I rode it long enough it would eventually fluctuate between 35-45mph with an occasional reach to its top speed at 54mph. When it gains speed it kinda sounds like the engine when jumping waves kind of like it’s sucking air. I took it to a shop and he did a diagnostic which had no codes but the IBR that was replaced last year. He checked the spark plugs which were bad so he replaced those. Did a compression check that came back 151,152,154. Took it for a test ride still runs with a vibration and tops out between 35-40mph (not sure about RPMs) I brung it back and he checked the fuel injectors. All good. What could be the problem??? He thinks maybe bad gas (which I just put in this ski and the other) or the computer is bad.
Ps. I was not using the learners key, I tried it in sport mode same issue, I personally looked into the intake under the ski and the wear ring looked good I guess but no significant gap between the ring and impeller.
