Remote control lever rattling at 4K+ RPM

[Rossioloveio]

Hi all! I am a new owner of a 2014 Yamaha SX240 and noticed a rattling/strong vibration at RPMs of around 4K and higher. It seems to be worse or more prevalent when turning (even slightly) to the right. I’ve checked intake and impellers, but no obvious impediments. Performance remains stable, with speed, RPMs, etc. remaining constant - just the rattling/shaking.

Could this be an issue with the remote control lever itself? Or indication of a bigger issue? Or probably nothing - it’s just a quirk of a used boat? I’ve posted a video for reference.

Thanks in advance for any input!

Most likely means that a reverse gate is hanging in the jet flow. Raise the low nozzle and you'll be good.
