I think I am going to build a hot water box off the water from my kicker

. I am wondering about location, where do you have yours located? What would you change move etc.? How big is the tank? Would you put one in the next boat you get? If anybody has a pic of an aftermarket install that would be cool

I know I am going to have to install a thermostat etc I am just wondering about location would you move yours if you could and where to?
