Make sure and check the areas circled in red VERY closely. The lower keft area appears to have screw holes that are open. The upper left in the picture appears to have cracks in it from the photo(weakining transoms often start to show up in this area first). And the lower right is more screw holes. As for a jack plate it could be used, but the problem will be you wouldn't be able to trim your engine up as the cowling would hit the transom. You either have to cut the 25" down to a 20", or make your 20" shaft a 25". WELLCRAFT offered the V-20 with either a 20" or 25" transom from the late 70's to the mid 80'd. Early on they were all pretty much 20" since that was a long shaft, and later on 25" was the standard.
