I bought a 77 v-20 back in March and spent the whole summer restoring it . I rebuilt the 170 merc 4 cyl,gimble,and alpha one outdrive.While pulling the engine out I found out the transom was rotten .So, while I had the engine out I cut out the floor and transom and replaced the transom ,stringers,transom cap and floor.It was a hell of a job but I got through it . It turned out great. Ive gotten it all back together and it runs great. Now all I need is a bow rail and a couple of new chocks. Anybody got a good used one or know where I can pick one up . thanks Carroll
