Hello Forum, I have a 1980 CC251 with an original Marine Power 305K. I would like to replace it, rather than rebuild the original engine, with a PCM 351W, with a Velvet Drive 71C tranny. The motor is recently rebuilt, stroked and bored. The question I have is, what challenges do I face regarding mounting engine and transmission, prop shaft alignment, and changes required to current prop? I have seem images of CC John's installation, and would like to see the advice of the forum on this.
