Advice f60a prop Yamaha 4 stroke

[dop]

Gday all
pulled off my prop to grease the splines and promptly forgot which way the washer goes into the hub of the prop. Looking in my manual its part no 4.Does the flatter side drift into the hub or is it the otherside. Hard to explain ,according to the manual 1st put in thrust washer 2nd prop 3rd spacer 4th washer 5th prop nut 6th cotter pin.Hoping some one out there can figure out what I'im talking about and can help me
Regards Peter

The prop shaft usually steps up in diameter where it enters the gearbox.

The thrust washers have a taper on them and the tape goes toward the tape on the shaft.
