Sea drive transom repair? Sea Cast?

I have an 85 center console V20 sea drive. The sea drive was removed and a custom bracket and a 200 merc was put on by the original owner. Recently in slightly choppy conditions I have noticed the transom flexes and the stringers on the inside do as well. I noticed this by looking at the inside of the transom through doors to access my oil reservoir and bilge area. I am almost 100% positive I need to redo my transom. However after researching the seacast stuff I cannot seem to find an example of application such as mine. Could I remove the gunnel cap and bow rail all the way around the boat and then do the chainsaw thing (sounds bad). Would Seacast be the best method? What should I do with the stringers? Considering im still in school, I need to go the cheapest route and at the same time I would like to do it myself. Any suggestions let me know

There is another thread here some were with a different product then seacast that looked real good and cheaper!!

As far as the stringers go, you will have to cut back to good wood and add new wood, add knee boards up the inside of the transom skin and glass all.

After you done just redrill and install the bracket in the same place, you will have to plug the holes so the stuff doesnt run out when pouring.

Im not sure what you mean by knee boards. the transom has two triangular pieces , running fore and aft, that are fixed to the transom. Im assuming these are the stringers!?!

Arjay 6011 or Nidacore pourable are both alternatives to seacast and less than half the cost. I have samples of both and I'd swear they are exactly the same. I'm going with one of them when I do my transom this winter (even though I'm sure I'll be ridiculed).

The illustration helps a good deal thanks. And after looking at it, it seems i didnt mean stringers. It was the knee boards i was looking at moving. So what would be the best way to remove my old wood and best method of pouring it in considering i have a closed transom?

Take pics. of your transom/cap area. I would use something as seacast or one of te other products. The cost of West System will kill ya.

If ther knee boards are moving then I am sure were they are connected to the stringers is rotted, you will have to cut out and replace all!!

Any idea how much this would cost to get done by a shop?

Big bucks, I say at least $3500.00
