Title is something issued by a state, different from manufacturer's certificate of origin which is needed by the first user to register a brand new boat.
All but possibly the very earliest DSII's should have the modern style HIN (hull identification number) required since 1972. That should allow you to find out if it was ever registered in your state.
Since you are planning to register in Mass, you might want to research the local regulations on the web. From what I can see based on a quick search, that state does not allow for registration of previously unregistered boats (even from out of state). (You would be lacking one of the documents needed for the registration).
If your DSII has any fittings where an outboard could be attached, it might fall under their classification of
"motorboat".
In your case, I would contact someone from the state and get definite and accurate information before spending money (or risking a fine).
