Looks like nobody wants to take up you question Buc! I was wondering the same thing. Maybe OMC had a bunch of parts left over from pre WW2. They might have just built motors like crazy to give the dealers something to sell. My motors are 4404 models also. One has a twist grip the other doesn’t. One has a cast aluminum tank the other has a tin metal tank. One has the fancy transom clamps with Evinude embossed in them the other has metal rods. One has brass tubing fittings on the cooling lines the other has rubber elbows. Every time I look at them I find something different.
Kinda like Johnny Cash’s song 49,50,51,52,53…anything will do watermobile!

I see I don’t have my other four Zephyr’s serial numbers recorded,
and I can’t remember what nuances there are between the
rest of them.
What I remember most about them from the 70’s was getting it
to run in a 50 gallon barrel by my dad’s garage, then carrying
the heavy thing down the hill, to the dock, wrestling it in the old
wood boat, and it not starting again! Back up the hill into the test
barrel, and it would start right up, lol.
On the rare occasion I got one to run on the boat, there were smooth
runners, and nice and quiet idlers.
