This afternoon when it was way too warm to be working outside I came in and reviewed the many forum strings on this transom repair. I saw one detail I had not been thinking about and that was isolating some areas for swim steps, or in my case a small platform. I would have had all of this back together before I had thought about that. I have some high density/high strength stuff that I think would be perfect for isolating the exhaust and creating the internal strength needed for a platform. I am not ready to design the platform just yet, but putting some strength in now is easy enough to do. Thanks all you guys that figured this stuff out first! It was also good to know that my transom is no where near as bad as many have had to deal with. Meter readings near the back stays are all good, as are those around the deck drains. Those holes will get some attention, but nothing very serious. I do get to fill one other unnecessary hole from the old bilge pump outlet that is now routed to the sink drain.
