I have put some performance exhaust on an old 1992 Yamaha Waverunner. There is a nipple coming off the muffler, and there is a hose that came with it also. Is this muffler supposed to be water cooled or something? I have a nipple on the side of the boat too, so it looks like the same size hose would connect there. I am just wondering if typically water is mixed into the exhaust for cooling purposes or what. If not, can I just run the hose from the muffler to the port going out the side of the boat. Any help or explanation on the theory of this would be appreciated. Thanks in advance.<br /><br />Russ
