    Flexible exhaust

    Has anyone tried using this off a water box to the through hull ? 316 stainless. Was thinking to get over sized and use a piece of silicone hose on the clamping sections between the hose and exhaust fittins with a t bolt clamp or two. Just a thought.

    Im using marine exhaust, its wire reinforced rubber hose that designed for the "wet" part of boat exhausts, it relatively flexible maybe not as much as what you posted but I would be worried about the durability of that stuff...

    It works well, and can take fairly high temps, I am running a fair amount of water into my exhaust as I dont have a waterbox where it can build up....

    You will get water and exhaust seepage, as that flex pipe is used for routing exhaust in an open environment...not to be used in a closed hull setting.

    Its spiral bellows, which is just a tight interlocking system. It floats between itself, which gives it flex. It is not completely sealed...

    Mainly used on Big Rig trucks to aid in stress relief between the motor and the tall exhaust stack. When those motors torque up they can snap any exhaust pipe if its hard mounted...Also used in shops that have rolling dynos, they just toss the hose OVER the exhaust and run it out the shop...
