Hi guys I have a 1976 Evinrude and I measure the shaft length at 23" not 20 or 25. Does this sound right? I measured from the transom hanger down to the cavitation plate. I bought this motor over ebay and was told it was a long shaft, now it looks like it falls somewhere in between. I'm confused by this,<br /><br />Thanks for the help ( in advance )<br /><br />Ron
