Drive shaft difference

[timguy]

Hi good morning can anyone let me know what the difference is between the 1958 and a 1959 Johnson drive shaft shows different part number 305267 (59/60), and 304933 for the 57/58?
Thanks, Tim

Hi. 35.

Looks like lots of changes between 1958 and 1959, different crankshaft part number, change in midsection from old style to the "super quiet" midsection, different water pump part number. spline count, diameter, or lenght maybe different. Not sure, I don't have them to compare parts.

Impeller driven by a pin or woodruff key makes for a different part number.

Yes that could be all it is. I'm selling one on eBay and the guy wonders if it will fit a 59. Thanks guys, maybe I'll message old Joe Reeves he might know too.
