pour transom solid?

[DANNY18SC]

i just got a 18 and the guy had to re-do the transom. instead of wood and glassing it in, he said he poured it solid with resin and chop glass. i have had to drill the scupper holes and it is all solid. he said he had some helping him and he poured it all at one time. has anyone done this? or heard/know anyone who did? what are the pros and cons of this? should i keep it or scrap it?
