evinrude 75hp short shaft

[john rowley]

I just bought a short shaft evinrude 75 hp from a guy. He said it was the same as a Johnson stinger. He said a stinger is a race motor. What exactly is a stinger and is there a chance this motor is not an Evinrude equivalent of a stinger? Were all short shaft Evinrude 75 hps made for racing? What is the difference between a stinger and regular 75? Just need some information and want to be educated about the motor I have.

None of the production 15" or 20" omc 3 cylinders were "racing" engines. The 15" version was a stock engine that was accepted into APBA E class, V bottom and Tunnel classes. The 15" version had a Nitro gearcase. It was smaller in diameter than the "club" foot used on the 20" shaft length.

The Johnson 3 cylinder 75 "Stinger" was just a name on the cowl. The 15" and 20" 75 h.p. motors carried the name Stinger.

Now, the V-4 racing engines built from 1970 to 1974 were called Stinger and Stinger GP.

The Evinrude version was called the Hustler. They were pleasure motors that could be raced in some classes years ago.

The 75 had bigger carbs than the 70 and slightly different porting ( takes 5 minutes to alter a 70 to the same)
The unique part was the small gearcase, although common to the 2 cylinder models, had a higher gear ratio 15-28 or 1.86:1
The other good part was Merc had nothing in that class that could touch it on the race track

Early in the 49 ci racing class the Merc 650 XS dominated. It was the preferred motor especially in Europe. Later when racing shifted gears to modified motors, Selva, Konig and OMC took over ... later rule changes favored OMC and they absolutely dominated.
