transom questions

[natchalkley]

so I am in the process of replacing the transom on my 23cc. I go the core in last weekend and today I started with glassing it in. I thought I knew what I was doiing but now I have a question. I saw that Strick did 2 layers of 1708 on his 20cc, so I figured that that was what I needed to do on this. Now today I read a post that says I need 4 layers here instead of just 2 . I am planning on putting a 300 Suzuki on probably an Armstrong widebody bracket w/o the platform(want to leave the option of cutting in a transom door at some point). I was planning on having a full backing plate made for the inside of the transom to distribute the load more evenly.
what im getting at is: should a put 2 more layers of biaxle(1808) on the inside and skip the backing plate or should I go with my original plan? I am planning on putting 3 swivel rodholders in the transom for Giant tuna fishing so I dont need to support a livewell or anything.
