67 Larson American--Weird rubber in KEEL?

[zarillus]

Guys, i have a preety bad shaved keel which takes on water and while sanding it and getting it ready for repair i noticed a black rubber like substance just before i hit fiberglass.Does anybody know what this is? It doesn't look like a Keel guard just part of the very bottom of the keel.

Did Larson used rubber in there Keels for that year?

If so how would i go about replacing that or adding it back?

Never heard of a rubber keel in a boat. Every one I have seen has been wood. I know that some Ski boats in teh 80's used kevlar in thier hulls. Got any pictures?
