seacast for sure, did mine 3 yrs ago and solid as a rock now, champion 184 with a worked over 175 fast strike (220 hp). not all that hard but you do have to be somewhat careful when cleaning the transom so you don't hole the hull.
the short version of my repair, 3 days total but I had a shop and experience with glass work, figure a week at least if you do it.
