Hey troubleshooting guys and gals need some help. 2007 230 challenger Se with twin 215sc engines.

Was cruising river tonight went over a pretty good wave from a wake surfer doing about 25 and accelerating thru like normal, didn’t feel like a hard landing, about 30-60 seconds later my starboard oil light/alarm goes off. I immediately turn it off and move over to side of river. First check is oil. Oil is fill and looks like new, it’s only month and half old. Check of coolant and all looks good. Don’t see anything out of place in engine bay. Fire engine back up and it starts fine but super rough. Not like something stuck in impeller shake, just rough. Port engine is super smooth. Shutout and wait then repeat fluid checks. Also checked as best I could to see if mounts have shifted and don’t look like they did. Also nothing leaking in engine bay when running either. Decide to try to get back to marina. Start off slow with both goes without any warnings. So I push a little. RPMs jump up faster on port(not the one having issues) than the starboard. And seems really sluggish as if I’m dragging something. Get up on plane for about a minute and alarm again. Repeated steps and no change can’t see anything. Limped back to marina and docked for night.

got it home. Pulled jets and inspected, nothing around impeller etc. started with jet off and still running rough. See video link below.

replaced plugs with new. Verified spark by grounding and turning over each. Checked resistance of coils to and in spec with book. Even swapped with other good engine and same result.
Checked supercharger and feels like good engine. No spin etc. both coolant and oil are full. Oil is about month and half old XPS.
Thoughts?
