Outboard mounting on stern

I really tried to avoid unnecessary work and I thought the outboard mountings were fine, the wood seemed solid, at least on teh outside. When I removed the rotten rubbing strake it was clear there was rot at the top of the mountings so I removed them and found they were rotting from the inside, as shown below. The timber was as soft as balsa wood.





I laminated some teak offcuts and then shaped them as below so now ready to fit once the hull is ready but that is another story...old and new mountings below.
