i have a johnson seahorse outboard 20 hp motor model 20 ba serial number 26711 would like to know the year it is.
It is a 1957
I found mine on the upper part of the shaft, on the left side.
Built in 1982 according to several website. My sea-horse serial number is only about 100 serial numbers from yours... in the same batch.
1961
The 77 in the model number 10R77A means it was manufactured in 1977.
1946
Your 1958 Johnson uses a 24 to 1 mixture.
That is the model number not the serial number.
