1972

the following should help
OMC Johnson Evinrude Model Guide 1973 1990 Johnson Evinrude 2HP 40HP Outboards SERVCIE REPAIR MANUAL year...

Please check the model number and see if the last 3 digits are EIA, instead of E1A. If so, it is a 1990.

the serial number is not consistent with johnson serial numbers as all have 2 letters followed at the end by 2 numbers which indicates the year of manufacturer 9 ( ft17598 indicates it was mahe in 98)
There are pages on the net explaining when a serial number is used but it must be old as johnsons have used model numbers for identification since 1960's
probably better if you take it to a johnson service dealer as they may have the johnson factor list for serial numbers as you will have to identify it to get parts
go google and type in manufacture date of 40s johnson td 20 outboard serial number 63191
if that shows no results just cahange some words in the search

I have never seen anyone answer these questions.if you looking for a condenser they are all the same.eg a 1965 40hp condenser will fit a 1955 20hp

To get the year of Johnson and Evinrude outboards use the word "INTRODUCES". Each letter corresponds to "1234567890" respectfully. It's best to check with a model year reference book, but this motor's model number contains "CC" which would indicate it's a '88.

yes if yuo go to iboats.com the forum will allow you to search by serial number and give info on your outboard.

Hi have you tried it with the stop switchl/button disconnected, if so you have only got the stator under the flywheel left to replace, regards Phil.
