I really don't mean to be a smart alec but I have a question about the routing of your water lines. I can't quite tell but is everything being cooled off of 1 inlet? If so, and you have a closed top, I think you might end up with heat issues. It might be better to run one into the engine head and 2 out of it to an outlet. Then a separate inlet from another pick up to the header and pipe flange. Better cooling. I have a similar boat and I have had heating issues in the past when I did not run dedicated lines (2) to the engine, header and pipe flange (Especially in Florida heat). Just a suggestion. I think the boat is awsome.
