Mercury 3.5 HP 2007 Long or Short Drive Shaft?

[sharky5353]

How do i know which type of shaft i have? The parts manual online here doesn't show a size difference.

When measuring my engine, from the top of the drive shaft to the center of the propeller shaft is 24".

It is 19 1/2" from the top of the driveshaft to the next joint.

Please advise.
By the way, my engine serial number is OR173092 - Jan 2007 F 3.5m

Thanks very much in advance for responding.

Can someone please answer me?

I called in, Boats.net said to post here and a professional would answer my question. I am not sure how this works exactly, or if the experts are paid or not, but i sure would appreciate the help.
I can't purchase the new part from you guys unless i get an answer if that helps.

Please, can we get a tech to answer this for me?
If you need any more info to determine this, please ask.

Thanks.
