The 4-hole motors were made by Johnson. The # of holes refers to the holes in the can (a new #53689 is a two hole motor). They all require pretty mich the same amont of maintenance (from zero to constant, depending on your preference ).

Bottom line is the 4 hole motors were more consistently fast than the 2 holes are today, although the modern motors have better magnets and should last longer.
