Hello, I recently purchased my first jet ski, a 1996 sea doo xp. After taking it out on the water for the first time, it ran great, and rode even better. After maybe 20-30 minutes of riding, however, it struggled to get up on the water. The engine revs fine, it didn't bog, but I would have to use all the throttle I had in order to get up on plane. It would run ok once it got going, but it took maybe 5-6 seconds of full throttle to even get up onto the water. It also felt like I lost some top speed, almost like the throttle wasn't fully opened. I am currently in the process of rebuilding the jet pump (new bearings, wear ring, jet pump cone, etc). Furthermore, when I took off the old jet pump cone, it was full of water. The o-ring on the cone looked very mangled and worn out, and there was a large strand of metal inside the cone. Also, on the engine side of the drive shaft, one of the rubber bumpers was missing entirely. Would any of these lead to the kind of issues that I am experiencing? Is there something else that I am missing that should be replaced or inspected? I apologize if I overlooked anything or am asking a question that has already been asked, but I have gotten mixed answers and am currently very stumped and confused.
Any advice or tips are greatly appreciated. Thank you!
