Abstract
The present invention is a device which redirects motor exhaust fumes a distance away from a boat. This device can be applied to a boat's propulsion motor or to its generator for purposes of preventing carbon monoxide poisoning of a boat's passengers. The device includes an adaptor for attaching to a boat motor exhaust port and an elongate extension hose attached to the adaptor. The extension hose is made buoyant through use of a plurality of flotation collars disposed along the length of the hose. An extension rod is inserted into the collars to keep the hose rigid and the distal exhaust end of the hose directed away from a boat to which the device is attached.
