I've not built a bracket before but I do have some experience with fiberglass. I built three fiberglass over plywood boats before starting this project. I don't know that I would try building a bracket and glassing it on which is why I extended the stringers through the transom. This way the stresses are spread out from the hull through the transom and to the motor mount. That being said fiberglass is stronger than you think it would be especially epoxy. Either way I added more than I think I needed. As far as cost it took 4 sheets of 3/4" coosa with some to spare. Maybe 5-6 yards of 50" 1700 cloth and 20 yards of 12" 1700 tape and roughly 6 gallons of resin. All total its been about 35 hours of labor and $1800 in materials. Ordering an aluminum bracket might be cheaper and definitely easier but i prefer to do things myself.
