I'm just a cheap basterd, I guess...
I've got a '75 75hp evinrude on my big boat and a '78 25hp evinrude on the small boat. Until they crater, I'm gonna keep running them.
If I had to buy a new motor today, I'd go with a another evinrude or a tohatsu.
That 75 hp Evinrude will outlast you. Spray a little clear lacquer (99 cent spray can from Wal-Mart) on the wires and coils and she's good to go for sho.
