I dont think it will fit well. I think it will be too narrow in the front because of the V20's flair. I bought a Cabelas cover on Ebay that was designed for a 20-22' Deep V with Bow Rail. The cover I bought was for a I/O but i just stretch the cover over the top of the motor and it works well. I wouldnt trailer with this cover but its snug enough to keep water from puddling and debris out of the boat. I'm not sure if you have a bowrail or not but that is definitely something yo want to consider when looking for a cover.
