Exhaust system guidelines for various generator set locations follow. Where exhaust lines would require passage through bulkheads, it may be more practical to use port (left) or starboard (right) side exhaust outlets. This would be especially true where long exhaust lines to the transom (rear) could cause excessive back

pressure. Information and illustrations of stern (rear) exhaust installations also apply to side exhaust installations. Should any information regarding installation conflict with U.S.C.G. Regulations, appropriate Regulations should be followed.
