Nice, but unfortunately also wrong. All Boxsters up to 1999 are dual rows, 2000-2001 are a total crap shoot and have to be pulled apart to determine which bearing is in them. 2002-2004 are all single rows. 2005 starts another crap shoot year where it can either be a single row, or the oversized non serviceable version. Again, the only way to know is to pull the car apart and look. 2006-2008 are all the non serviceable units.

This list has been published over and over again, but those of us that actually retrofit these cars for a living have seen it be wrong often enough to ignore it.......

Where did you get this information from?

+ many engines have been retrofitted so even IF the list was correct for the OEM fitment at date of manufacture ,it may be wrong now

It has been misleadingly posted on several forums, like Pelican.

I would suspect from this Pelican Technical Article;

Pelican Technical Article: Boxster Intermediate Shaft Bearing Replacement and Upgrade (IMS) - 986 Boxster (1997-04) - 987 Boxster (2005-06)

Correct. According to the engine number and year, we were certain my car was a double row. They pulled the clutch out and found.... hold it.... single row. Double row now tho.
