Mercury v6 cooling

[91eagle]

If you wanted to run a Mercury V-6 powerhead on a bench for like break in time or dyno testing and stuff like that.... How would you do a closed cooling system with a radiator .?... Can it be done and is it hard to do ?????
Thanks for any info ..
Sorry if this is a repeat question I tried to search here and other places and didn't find anything on the subject

Need a radiator, water pump and figure out how to make it all work. There are guys that run them on carts and stuff like that with cooling systems, it can be done.

Is there a reason why you would want a closed system? Most all engine dynos and run stands use a “loss system”. Build your stand....give it a base plate with a simple valve that your garden hose hooks to, and go to town.
