1979 basstracker project

So this boat has had a million memories made on it. It’s very sentimental to me and I would rather watch it rot away then ever get rid of it. Its a 1979 bass tracker and it was passed down to me a while ago. I have taken it literally everywhere. I have hunted out of it, fished out of it, and made lifetime memories with family and my closest friends. I want to be able to take my son out on it when he’s old enough and give him the same experiences I had and make even more memories with it. She’s tried and true that’s for sure. It has needed some love for sometime and I’m fixing to show it some. My goal is to replace the rotten transom, repair some cracks and holes, paint it, install new flooring and possibly find a newer style motor for it. My goal is to have it completed within a few months.
So here’s where we’re gonna start - the rotten transom. It has now been removed and the next step is to make a aluminum insert to replace the wood to insure it will never rot again and to reinforce the transom so it will no longer flex.

I have a question about the transom, I want to eliminate the wood and make an aluminum transom piece out of square aluminum tubbing. Is there any cons to this? I was told that if I donot use wood then the motor would rattle the boat to pieces, is there any truth to that?

Anyway here are some pics, and I also have a pic of the aluminum piece I want to use instead of wood

Hope you guys enjoy and follow along with me as I tackle this project!

My guess is that the aluminum would crack once the motor is bolted on. The wood would act as a cushion per sé, and also absorb vibration.
If you seal the wood properly it will last a lifetime, given the factory junk lasted 40 years.
