Three aluminum outboard props.
Two, (the smallest) have shear pin slots.  The white (small prop) is approx 9D x8P. The small black prop  is approx 7d x 6P and looks like it is off of a 3.5HP Nissan, Merc or Tohatsu. The small black prop is in good condition with some paint chips, and ready to use. The largest prop has spline drive and is approx. 10D x 12P. The two white props may be good enough for a spare or core.
