    pull the spark plugs, see if the motor can be rotated by the flywheel manually.
    if not pull the gear case and try the flywheel again.

        Safe this way, but initially carefully just try turning flywheel to test if engine seized (ignition off!). To test if lower unit has seized turn prop in neutral.

            Not an accurate test,
            pinion bearing can seize and prop can still be turned fine.

            Like Rod said, try turning the fly wheel by hand after removing the plugs, if you cannot them remove the lower unit and try again.
