Seadoo wake engine reving noise.

[Westminsterfly]

Hi y’all first time planting. I was riding my 2016 seadoo wake pro 215 today and realized while riding it all of a sudden was vibrating in my feet a lot more than usual and making a rough sounding noise like a car reconfirm it’s engine. This would only happen above 30mph typical or if I put it in sport mode and started from a stop. I took a video to try to better describe the noise it makes but don’t think I can upload it again new haha. Thanks so much for any insight into what could be causing it.

Starting with the obvious items.

1. Foreign object causing out of balance with the driveline.
a. Driveshaft clear, nothing wrapped.
b. Impeller clear, small rocks can get stuck between blades.

2. Impeller blade damage. Chipped blade.

3. Nose cone on pump loose. Loctite required.

4. Pump mount bolts broke or loose.

5. Pump bearing shot.

6. Engine mount bolts loose or broken.
