transom trouble

[blackfin29]

I have a problem and I am hoping for suggestions....I recently bought a 76 CC with a blown motor, the boat seemed solid (floor and transom)I purchased a 140 suz. 4 stroke after it was installed I had a leak by the bolt hole....the boat yard that installed the motor just told me that the tran. is soft in that spot so the bracket bent, that's why I have a leak (they think it can be repaired by cutting the bracket and re gluing everything)....my question is this if I replace the transom (after the season)how do I deal with my brand new 20 inch Suzuki, I assume the correct thing to do is raise the transom, but then what?
