I would remove all the access plates to clean out the tank. I opened up the aluminum water tanks on my 1986 boat and found what looked like gravel inside. In reality, it was not gravel but aluminum salts or something like that. Anyway, I pulled out fist full after fist full of the stuff. Also, some gross slimy stuff. Then I dried the tanks and scrubbed them. I don't drink the water from the tanks, but I feel better about using it and there is less to clog the filters.
Good luck finding and fixing the leak. I hope both tasks are simple.
BTW, I think you have a really, really cool boat and I appreciate your sharing your thought process on finding and buying. Hope you have many great adventures with your fine crew.
