Exhaust gas is hot. Always ensure that there is nothing that is susceptible to heat damage within 200 mm (8") of the
effective area of the exhaust gases (e.g. ropes, fenders or the side of another boat). All lead-through's raise the
temperature of their surroundings. A wooden deck, in particular, may dry due to the heat. Remember that the surface of
the lead-through is hot during use.
The exhaust gas pipe must be made of stainless steel. If necessary, seal the connections between the exhaust gas
pipe and the lead-through with heat-resistant silicone. When installing the lead-through to the stern side or to otherwise
leaning position, be sure that the water do not stuck the exhaust.
