Using Seacast or similar with 5in" Tarnsom Increase

Is porable transom a vaible option if done properly and bonded to new and old glass?

I would say its a viable option and would work if done right but me personally I wouldn't use it to raise a transom. I think what Flexpat says is the best word of advise. Long as you have the proper layups on each side you will be ok long as the core has the compressive strength for hardware. Make sure it is grafted to the old glass well. 12 to 1 and blend it in a ways with the inner and outer skins. I could see where this product would work well to fill voids vs cutting something open but I like the idea of wood or composite (dense enough) for transom cores. Especially if my motor is hanging off it or a bracket. There are a lot of loads from the outboard. Also just curious? What dose this stuff weigh? A 5 inch extension probably not so much but a full transom poured with this stuff would weigh a lot I would think.

Edit:
I really don't know much about these type of pourable products or have used them so I really shouldn't comment about them at all anyways. Those who have researched them and used it will tell you better than I. I would worry it could crack but with the technology today it may be a good product.
