A good patch will be stronger than the original hull. I'll leave it to the experts to tell you the best way to do it.
You might want to consider this. I put a 1" bronze scoop in for feeding the baitwell and washdown pumps. Teed to two 3/4" lines for the pumps. I ended up with too much forced water for a 1-1/2" overflow line from the bait well. At cruise, the forced water was more than the 1-1/2" overflow could handle, even with the pump off. I did not want to choke off the flow so I installed a second scoop facing backwards and connected the overflow to that. The suction created at cruise speed stopped my overflow problem and I still have plenty of water to keep the bait frisky.
I soaked a piece of 1/2" plywood with resin, roughed it and the hull with 60 grit, then used thickened resin to stick it down. After it set, I used a hole saw to go through the plywood and the hull, then put several coats of resin inside the holes. I really gobbed on the 5200 when I installed the scoops, then wiped up the extra. I am pleased and confident in the installation. I am sure there are other ways of doing it but this worked for me.
Tip:
After one trip, a small amount of bilge saltwater started turning the bronze green. I wire brushed the bronze stuff clean again, then "painted" the bronze with resin. After a year I have no green on the bronze. It's dull looking but that's better than green.
