I understand your concern about the water. There is regulation and partial recirculation the set up plan. The appeal is space saving, where I live now I just don't have room to store anything that is not space economized and doesn't break down, the radiator adds too much to it. I'll let you know, and maybe take a pic when I try it next spring if it works. I think it will work, but I'm going to try a lower value mule motor first to be sure and get some experience with the cooling control and gauge panel etc.
I went ahead and ordered that deal on that cam you gave me a tip on, (I think), never ordered from KMJ before. As I was reading the specs I noticed the ad said only one left, so I decided to pull the trigger. Thanks again, John
