Brandon, What you describe is a Ferrite Bead. They are used to keep radio frequency interference to a minimum from the fan. Mine didn't have the beads, but I put them on other ;power supplies or transducer wiring if I get RFI. Leave it in place. I use the small plastic clips to hold wires in place.

That makes sense. I think I want to mount two of them on the coachroof in each aft corner by the door. Question is, do I just thru-bolt them? Or should I glass in a wooden block to screw them into?
I'd like to just epoxy a piece of teak to screw them in to but I'm not sure how well a piece of teak with underlying epoxy but without cloth over it will hold? I could also glass a piece of wood in by laying glass over it and painting it but I think of the three options I'd p probably have the hardest time getting that right.

I have used teak and other woods, glued with Epoxy directly to the fiberglass. Technique:
mask off the area on the fiberglas,
Sand this with #80 grit, get any surface paint off. Clean with alcohol.
Rough up the back of the teak block (I bevel the front edges). Clean with lacquer thinner to get the oils off the surface.
Use a slightly thickened or "G Flex" epoxy on the teak. Leave a couple of spots clear of the epoxy for the hot glue.
Use Hot glue in several spots on the fiberglass, to hold the teak block in place until the epoxy dries.
Oil the teak block, and attach the fan etc. |
