How to fast tell if the VRO pump is working on my 1985 EVINRUDE 90hp VRO V4

[Auriga]

Hello,
Recently bought a used 1985 evinrude 90hp vro from a buddy. Not sure if the vro pump is working or not, and I asked him what to see to tell if the vro pump is working, which the pump looks shiny and been told the pump were replaced several months ago. After start the engine after stall for about 2 times, it runs well and sounds good. And I see some white smoke out of the exaust which I think looks like the oil been burned, is it a sign to tell the vro pump is working?
Plus, the vro primer is full of oil which I cant squeeze it and there are barely some oil in the tank when I pick it up.

Mix up some 100 to 1 oil /gas mix in fuel tank,draw a line on oil level of vro tank.Take boat on water for a slow cruise and check vro tank for oil usage.Only time vro squeeze bulb needs pumped is after oil lines or pump has been worked on.
