being a 73 i assume it does not have trim & tilt. the AV plate, the flat plate above the prop, should in line and 1 inch higher than a line staight and even with the keel of the boat. put a straight edge on the bottom of the boat, the AV plate should 1 inch higher, and inline with the straight edge. if it's not in line move the tilt pin.

The best speed is to run it as high as you can without it ventilating excessivly (prop sucking air from the surface). Too much air sucking, drop it down a hole. Some boats will tolerate the plate above the bottom, some won't.
