[Germanrider]

Hello I have a scary noise in my superjet dont know where it comes from.
Today I want to check the Hood hose and regogniced that the noise is on cam.
Today I filmed the engine to show you the noise.
Would be nice if you can hear it. It is the howling noise you here in the movie uploded here

some one have an idea what could it be?

Outside when I am riding the ski it louder than on the movie and specally I hear it when I just idle a little bit.

Not sure what sound I am listening for? Sounds rich and like normal vibration sounds.

Sounds like impeller rub to me.

Have you tried running it and putting your hand on what I’m assuming is a AM waterbox in the left corner of the screen? The one that looks like it’s having a seizure? Lol

Sorry don’t know what you mean

Bottom left corner of the video there is something violently shaking around that seems to match the rattling noise I’m hearing. Appears to be a aftermarket waterbox.

Find a buddy with a trailer and drop it in the water enough to run it with the hood off, best way to see whats going on, i lesrn my headgasket was on its way out this way and discovered that it was filling my engine bay with water, could work for you to find your issue.
