Mercury 9.9 Broken Drive Shaft - is it Long/Short/XL
The drive shaft on our 1991 Mercury 9.9 outboard snapped this past weekend. Took it apart and it measures 25".
I've been looking online and the parts diagrams provides several choices with descriptions of long, short or extra long... no where can I find how to determine which version we have (the clymer service manual doesn't say anything either). I'm baffled that the part selection wouldn't be a simple matter of quoting the overall shaft length (and diameter if required)? Am I missing something?
I would be grateful if someone could clarify what short, long and extra long mean?

thanks for the info.
I also found another thread that was discussing this (don't know why I didn't find it earlier - outside of the mercury forum), anyhow reference diagram shows where to measure: http://www.iboats.com/ref/shaft_length.html
Still astonished that they wouldn't quote overall shaft length.
