I was wondering if this could have been fixed, wihtout a high price. I have a 72, 120 Chrysler outboard engine and I shot a connecting piston rod right through the engine block and now it only runs on three cylinders , but my engine races even at idle. and i was just wondering if it was ever possible to fix this.  i already grabbed hold of a 89, 90hp, evinrude because i think there is no hope...???
