Re: 1991 cajun 162zw(operation make it float)
Some drain holes are fine......I use the pour in expandable foam, but many have used the sheets, either is fine. Some will argue the foam isn't needed at all, but it's a CC requirement for smaller crafts. You should read some other threads, things like pool noodles, ping pong balls, etc have been used for floatation. So needless to say whatever you want to use is fine.
