I have a 1998 Evinrude 50 with a crack in the lower unit housing. I have been told Johnson/Evinrude are the same brand. What other year models and makes will also have the same lower units? I was in another forum where a guy said that the 50/60/70HP models between 1989-2001 will be the same lower unit housing. Then when I looked at the part number for the lower unit housing on this website it said the 35-50HP models between 1992-2005 all have the same lower units I am looking to replace. Need help figuring out what info to go off of.
