Hi Guys!

I have a old timber ski boat with a inline 6 car motor that has been
maraineized. i'm in the process of restoring this boat! currently the
engine is cooled with raw water running through the sump etc. there is
no pump or thermostat. I am considering changing this to a fresh water
enclosed system with raw water running through a heat exchanger. Now for
the Fun part, i am having difficulties finding information on what is
required, best practices and where to even obtain the bits. I am
assuming that i need a water pump or 2? one for the fresh water and one
for the raw? as well as a thermostat and heat exchanger. Are there any
other parts required? what should i be taking in to consideration whilst
doing this?? or should i even be looking at something different?

thanks in advance for you help!
