According to MarineEngine parts lists, all the parts for a 92 johnson 60hp and 70hp are the same including the pistons crank and oem carb. So where does the extra 10 hp come from?
 
Same powerhead just the carbs assemblys are different as venturi size and emulsion tubes are different...
According to the parts list at marineengines.com they both use the exact same replacement carbs.(apparently the 4th replacement upgrade) Did OMC just drop the 60 hp carbs?( or 70hp)
