  • Patent number: 9260171
    Abstract: A vessel propulsion apparatus includes an exhaust passage guiding an exhaust, discharged from combustion chambers into an exhaust collecting passage, to a catalyst housed in a catalyst housing passage, and a cooling water passage guiding cooling water. The cooling water passage includes an upstream water passage, guiding the cooling water taken into the interior of the vessel propulsion apparatus by a water pump, and a first and second parallel water passage connected in series to the upstream water passage and connected in parallel to each other. The cooling water passage supplies the cooling water from the upstream water passage to each of the first and second parallel water passages to cool the catalyst housing passage by the first parallel water passage disposed along the catalyst housing passage and cool the exhaust collecting passage by the second parallel water passage disposed along the exhaust collecting passage.
