Yea it definitely struck me odd because I’ve never seen it in other people’s builds

It looks just like that green floral foam used for decorating, holds water just like it haha

Two big blocks running the full length of the channel

And this was underneath the keelbox?

No it was beside it on both sides

Looks original cuz it had resin holding it in place

Then most likely the floor was removed at one time and this stuff laid in. I had rectangular foam pieces on both side of my keelbox too in my Viper, but they were gold in colour. Or it is original and just happened to be green. Regardless, get rid of it, and dont replace it. Foam just traps water.

Yea today I was doing some grinding on old glass the floor had to layers near the sponsons so it looks like the floor has been replaced for sure
