I bought our house in the winter and now that we're opening the pool we found an issue with the diving board base. It looks like the holes where the screws go have seen a lot of rotting and I am nervous about installing the diving board. You can see the issue in the attached picture. I've talked with the previous owner and he said it isn't an issue as he used very large washers. I also contacted someone about getting it repaired and he also talked about 'fixing it with custom washers'. Should I simply install the large washers or is there something I should do to repair it?
Thanks for all your advice,
