Reply To: 1953 Johnson or Evinrude 3 HP

[Bob Wight]

Don’t know if this helps but my Johnson Common Parts list shows the same piston ring set was used on all 3hp motors from 1952 through 1964 (motor models JW-10 through JW-19).  And the piston ring set part number is shown as #378412.   I don’t have anything that shows if that number was superseded by another number.   I do have a parts list for a 1958 Gale 3hp that does show #593425 as the ring set number so the Sea King would have the same number.
