Help with more info on Johnson stinger model

[leonardbaker1]

Hello,

I just got a Johnson 75hp Stinger. I have looked up the model number which told me that it was indeed 75hp and a 1975 model. The whole model number is "75ESLR75B" I was hoping someone on here may be able to tell me what the ESLR and the B meant.

The serial number is "J4303200" I don't know if that is helpful or not.

Any information or comments is much appreciated.

Thanks,

Lenny
