    I have noticed on my few small OMC motors that some have the small square pump and some have the larger one with five screws. How interchangeable are these?

    This is my question, too. I am curious to know if I can put the pump Don sent the link for or perhaps a pump from a similar era 6 hp on the 4006E. The difference in price between all the other pumps I am seeing available and the 0388684 pump is so massive. They all look like the same external layout and dimensions, are they that radically different internally?
