Marine drives having integrated exhaust and steering fluid cooling apparatus

Abstract:

A marine drive is for propelling a marine vessel. The marine drive includes: an engine; an exhaust manifold that conveys exhaust gas from the engine; a cooling jacket on the exhaust manifold, wherein a cooling passage is defined between the cooling jacket and the exhaust manifold; a cooling pump that pumps cooling fluid through the cooling passage so as to cool the exhaust manifold and the exhaust gas; a power steering actuator configured to steer the marine drive relative to the marine vessel; a power steering pump that pumps power steering fluid from a power steering reservoir to the power steering actuator; and a power steering cooler on the exhaust manifold and configured such that the power steering fluid is cooled by the cooling fluid in the cooling passage. In some examples the marine drive is configured for use in an outboard motor.
