摘要： An outboard marine propulsion device comprises an internal combustion engine having a cylinder head and a cylinder block and an exhaust manifold that discharges exhaust gases from the engine towards a vertically elongated exhaust tube. The exhaust manifold has a plurality of inlet runners that receive the exhaust gases from the engine, and a vertically extending collecting passage that conveys the exhaust gases from the plurality of inlet runners upwardly to a bend that redirects the exhaust gases downwardly towards the exhaust tube. A cooling water jacket is on the exhaust manifold and conveys cooling water alongside the exhaust manifold. A catalyst housing is coupled to the exhaust manifold and a cooling water jacket is on the catalyst housing and carries cooling water alongside the catalyst housing. A catalyst is disposed in the catalyst housing.

摘要： Methods, assemblies and apparatuses are for forming a cooling jacket in a cast part of a marine engine, for example in a cylinder head for the marine engine. A cooling jacket core has a longitudinally elongated first portion that forms a first flow path for conveying cooling fluid through the cast part in a first direction and a longitudinally elongated second portion that forms an opposite, second flow path for conveying cooling fluid through the cast part in an opposite, second direction. At least one bridge integrally supports the first and second portions with respect to each other during casting. At least one plug is configured to fit in the cast part where the bridge was located so as to separate the first and second flow paths from each other while sealing the first and second flow paths from an opposite side of the cast part.

摘要： An outboard marine engine comprises a vertically aligned bank of piston-cylinders; an intake camshaft that operates a plurality of intake valves for controlling inflow of air to the bank of piston-cylinders; an exhaust camshaft that operates a plurality of exhaust valves for controlling outflow of exhaust as from the bank of piston-cylinders; and a cam-to-cam connector that connects the intake camshaft to the exhaust camshaft such that rotation of one of the intake and exhaust camshafts causes rotation of the other of the intake and exhaust camshafts. The cam-to-cam connector is located vertically above a lowermost intake valve in the plurality of intake valves, vertically above a lowermost exhaust valve in the plurality of exhaust valves, vertically below an uppermost intake valve in the plurality of intake valves and vertically below an uppermost exhaust valve in the plurality of exhaust valves.

摘要： An open loop cooling water system is for a marine engine. A cooling water inlet receives cooling water from a body of water. A cooling water outlet discharges the cooling water back to the body of water. A cooling water circuit conveys cooling water from the cooling water inlet, through the marine engine, and to the cooling water outlet. A cooling water pump that pumps cooling water from upstream to downstream through the cooling water circuit. A recirculation pump that is located in the cooling water circuit downstream of at least one component of the marine engine and upstream of the cooling water outlet. The recirculation pump is configured to pump cooling water from downstream of the marine engine back into the cooling water circuit upstream of the marine engine. Methods are for cooling a marine engine using an open loop cooling system.
