Reply To: 1972 25 HP Johnson Outboard

[Bob Wight]

I went through this same issue when I restored a 1972 Evinrude 25hp a few years ago. You might take a look at the motor serial number before you decide whether you want to pick this motor up or not. Pressure back pistons and rings were used on all 25hp motors built after serial number 25202-01791 with all motors before that number using standard pistons and rings. I did a lot of shopping around and finally managed to find a set of NOS 385349 rings for around $30 per set.
