Filling a termite ridden stringer

[Amelia Man]

I have a 1996 Albin TE with a 300HP GM Diesel. Termites have invaded the stringers. I have treated the stringers and other suspected areas with Premise Foam Termiticide. I am in search of a product that I can pump into the areas where the stringers was eaten by the termites. The termites have left sections of wood in the stringer that would adsorb a polyester type resin. The area of most concern are where the engine mounts sit on the stringers. The fiberglass seems to be about a 1/4" to 5/16" thick.
Please advise as to how to proceed.

Rip the stringers out and replace

There is no magic mechanic in a can that fixes motors

There is no fiberglass repair in a can either. As AD stated cut out the bad, replace with new

You'll need to exterminate the wood.
