Makushin,
Your first post asked about the wiper on a CD22. Did you need info on the 22 or the 16? It just so happens I have my starboard wiper motor off now in the process of relocating to the top of the window. I measured it at 1.5" on the shaft length. I can see no reason why the port side would be any different. I have a 2002 22' cruiser. Maybe something has changed?
