How do I find out the year of my Johnson outboard motor?
The number to the far right is the model run or suffix. The next two letters to the left are the part of the code that determine the year. Johnson Evinrude uses a simple code if the outboard is a 1980 to the present model.

Are all Johnson Stinger 75’s the same?
Not sure where the different pistons & rods were used, but my 1980 Johnson Stinger 75 uses the same rods, pistons and crankshaft as the 70 of the same year. All the 49 cubers were the same bore & stroke. There might have been some changes as you moved into the Mod 50 and SST60 motors, but the stock service motors all used the same innards.
What is the gear ratio on a 1975 Stinger?
One is a long shaft 1975 Stinger on a Hydrostream Vixen. I am messing with jacking it up and will add a nosecone. It has the large gear case w/3 water pickup holes. The other is a 75 Evinrude short shaft and has the small bullet w/4 water pick up holes. The large gearcase gear ratio is 12:29 and I am using a 22″ pitch prop.
What is the difference between a stinger and a short shaft?
The actual cases are different as well. Short shaft had what they called the Sprint Drive. Smaller than the long shaft cases. The Stinger gets its extra RPMS from having smaller wrist pins and bearings, that are closer to the top of the piston, with longer rods. Carb is different than the standard model as well if I remember correctly.
