The ridgid hull is fiberglass
. I have no questions about that.
I am looking at the sterntube and how it is attached to the hull. It looks to me like it is attached with a silicone or some similar adhesive
and that some of that has come loose/ broke off causing the leak.
I am not sure of the sterntube material yet... FRP? Metal?
I am looking for ideas of how to reattach it and seal the leak.
