Hi All,
I have been looking to bid on a boat and have a short vid of the engine running and it sounds to me like there is a knock going on. not sure if I am right and would appreciate any thoughts on this.

Welcome
There is a slight something but unless something else shows it's head during inspection I wouldn't be concerned.

Is the engine stone cold there ? If so..might just be the usual cummins VM cold diesel knock.
