Yes, minimum octane for that engine is 80, but it also is suppose to be
leaded. I've found the old engines I've had ran much better on high test.

Don't bother with high test gas... it could cause cause starting &
idling problems as there is usually an additive package included that
just isn't required for an outboard. The minimum octane rating for 1973
Evinrudes is 80.
