HELP...what year is my v20

UPDATE......
well it's finally in the shop we will be starting on it this week. they still tell me it will be ready the 1st of april......some bad news or it may be good news, he said the main liner it gone would be to costly to repair, so they are talking about cutting the floor out of the liner and replacing it with wood and sealing it with resin...then carpet the floor......i was thinking of doing that anyway....it's going to be used mainly for pleasure and freah water fishing......
i hear alot about the use of a bracket on this site. do you think i need a bracket if i will be useing it on fresh water lakes maybe once or twice a year on lake michigan???????also i just aquired a bennett pump for trim taps. is there anyplace that i can get used trim tabs and wire harness?????????
