I guess i think its stronger, i know i used more epoxy than they give u in kit. When using starboard, u have to flame it. Basically wave it over a propane torch for a few seconds, this oxidizes the plastic and gives it better adhesion.
U could also use the gflex to fill the older screw holes, but plain epoxy would be better.
If you notice the two old screw holes to the left side of the transducer, i filled those.
I drilled out the older holes with a 1/2 drill and went about 1/2 deeper. Wet out the holes with epoxy, then filled with a thicken mixture of epoxy and cabosil. Let it stand out proud for a day or two, then sand smooth.
