Lower unit interchange

[rcb130]

Hello All,
I have a 2003 55Hp commercial rope start engine that needs the lower unit replaced. Does anyone out there know what different lower units will fit? Drive shaft is .75 dia and 17 tooth spline.
Thanks in advance for the help
Rob

Wish i could help! Dhadley or Ezeke could tell you if they catch this post.
I have a 55hp lower on a 1976 Johnson but its still bolted to the motor so i'm not sure of the length and spline size.
