Hi
My 2016 Mercury FourStroke 115 EFI has developed an intermittent grinding noise when running at idle in neutral. I recorded this video you can hear the noise at 24 seconds, 56 seconds and 1:04.
Does anyone have any idea what it might be? I have changed the impellor but still the same. If it was a bearing I don't really understand why it is intermittent?
Many thanks
PS the bubbles are Salt Away if you were thinking I was flushing the engine with detergent.
