Seadoo runs great. But when about an hr comes around at full throttle.. it seems the engine wants to spit.. like a plug fouling. . All of a sudden it will drop to 3800 Rpm then back to 5k. I have to almost drop all the way to 30mph to run without engine spitting.. I have new spark plugs and gapped correctly. I cannot figure out what's going on, it only seems to do this after engine is warmed up. But other than that it runs great. Please help
