Lower Unit is disconnected(removed) and the Impeller is removed from the drive shaft. In Forward or Reverse Gear, should the drive shaft be able to rotate CW and CCW by hand? Or should it only be able to rotate CW in Forward and CW in Reverse. When in either forward or reverse gear, I can rotate the shaft by hand both CW and CCW. Is this normal??? Would appreciate an answer so that I can reattach to motor or do I still have a problem....Thanks for any help offered!
