10 second video of motor sound - Anyone have any ideas? Yamaha F115

[Yamaha115neworleans]

Hey fellas,

I have a Yamaha f115 (2005) that I love, only 260hrs, it has started making a sound at idle that I cannot diagnose:

The sound kicks on periodically, I only notice it at idle, and it must be a system or part that does not run constantly when motor is on. Meaning it is cycled on and off by the motor.

I think this because it routinely makes the sound for about 10 seconds and then stops uniformly. Then about ~30 seconds later it repeats. And so on.

Any ideas?
Thank you all!

That high pitched sound that starts about half way through the vid?

Pull the lid, listen to the sound with a stethoscope ,broom handle, or chunk of hose. Listen at various parts of the engine.

Same here, too much wind noise.
