    I believe that "washer like piece" you note is the thrust washer - it should be able to come off and should slide easily on the prop shaft.

    If it's seized in the wrong place it cant do it's job. As you shift from neutral to forward or reverse the propshaft moves (in/out).

    Sounds like a little more than the prop is/was seized in the lower unit. Might have to tear the whole thing down and do some work on it..
