Mounting transom shield on wavy 1/4” aluminum transom

[hofmanntyler1987@gmail.com]

The transom has a bit of a wave and am afraid hat it’s going to have a slow leak once the Volvo DP-c transom shield is mounted. What are my options besides caulking the crap out of it? Some sort of backing plate on the inside of transom?

What boat?

I think and if I'm wrong I will be corrected, the transom should close be 2 1/4" thick for the driveshaft and coupler to work together properly.

Agreed, something is not right. Transom should be between 2 and 2-1/4" thick

Also has to be flat or close to flat.
