So I got these from Hardin marine. I don’t see where I can get risers. If I’d gotten crusader or pcm I could have done that but I was trying to avoid iron.
Maybe another brand would work in between or I have another idea with a friend who I think has a mill…let’s get this closer along and we’ll revisit it.

This needs a bigger heat exchanger. At this point, I might as well get an appropriate marine heat exchanger. Given the price of fittings and cooling needed it’ll be cheaper and simpler to go that route.
Now for full closed or half closed is next question.
