Older exhaust systems
Russ and 67-
Do you have some sort of mixing chamber after the copper jacketed section? You can see in my set-up that the gases are mixed with the cooling water in what I call the mixer (for lack of a better term) which is tucked up under the deck as high as possible above the water line. From there, it's a straight shot out the transom after about 4-5 feet.
I like this system as apart from the iron hot section, it's all copper. And, it seems highly unlikely that water could ever "back up" with this design.
