    I would not worry about it!
    It does mean your clutch packs are in good shape!

      Perhaps a difference between what could be considered normal and not really neutral? On my boat the shaft turns on stbd engine but not port. It turns very slowly, not enough to move the boat. Stbd shaft is easy to turn by hand. Port shaft is a bit hard to turn by hand and now I am thinking that is an alignment issue.

        Make sure the gear lever is in the correct position and not out of adjustment, best way to tell is put it in neutral and disconnect the cable at the transmission , it should line up with the lever with-out re-adjusting the cable..

          Maybe you've left the cruise control engaged

            The only problem would be for swimmers and fishing while out of gear and idling.

              Is this boat sitting in water that has a current? When I anchor out, if there's a good current, I have to lock the prop shafts as they will just twirl all night long. With the engine running, That could be enough to loosen them up to the point of current being able to rotate them.. Otherwise, I've seen all manner of I/O's and Inboards that will rotate shafts and props even in neutral. There's very little force behind it.. Heck, even if you have a car jacked up and in neutral, it will still rotate the front wheels, which you can stop with your foot.
