It is a reference to money that would be better spent on beer.
forget about motors until boat is ready and as i said before you will be most likely replacing transom and my analogy to car motors is valid. Quit worrying about it especially a measly two lb difference.
Since this is your first boat, find a good mechanic and bring him with you. Ive had over 20 boats and i still dont know much. However if you know motors, then do what you would do for any motor.
