Suzuki DF 115 ATL Minimal vibration on idle. Normal?

[Karnic]

Hi All.
Lately i was running outboard in tank and noticed a minimal vibration. Attached please see video. Was just curios if its normal or not on a four stroke. As you can see vibration is minimal but what are your views.
Also may i take this opportunity to ask on idle what RPM should read. At the moment mine is displaying a bit less than 600 RPM on idle ( 550-580).
Appreciate your kind views.

Looks perfectly normal to me.......exactly the same as my previous Honda 135 hp outboard

The correct idle speed should be given in the handbook.
