Abstract
An outboard motor comprises a first cooling system comprising a first pump configured to circulate the first cooling fluid through the outboard motor and a second cooling system comprising a reservoir configured to contain a second cooling fluid and a second pump configured to pump the second cooling fluid to at least one component of the outboard motor. A heat exchanger is configured to exchange heat between the first cooling fluid and the second cooling fluid to cool the at least one component of the outboard motor. The second pump is located longitudinally forwardly of the reservoir and axially below the reservoir.

An outboard motor extending from a top to a bottom in an axial direction, from a port side to a starboard side in a lateral direction which is perpendicular to the axial direction, and from a front side to a rear side in a longitudinal direction which is perpendicular to the axial direction and perpendicular to the lateral direction, the outboard motor comprising:
- a first cooling system comprising a first pump configured to circulate a first cooling fluid through the outboard motor;
- a second cooling system comprising a reservoir configured to contain a second cooling fluid and a second pump configured to pump the second cooling fluid to at least one component of the outboard motor;
- and
- a heat exchanger configured to exchange heat between the first cooling fluid and the second cooling fluid to cool the at least one component of the outboard motor;
- wherein the second pump is located longitudinally forwardly of the reservoir and axially below the reservoir.
An outboard motor extending from a top to a bottom in an axial direction, from a port side to a starboard side in a lateral direction which is perpendicular to the axial direction, and from a front side to a rear side in a longitudinal direction which is perpendicular to the axial direction and perpendicular to the lateral direction, the outboard motor comprising:
- a powerhead;
- a top cowl enclosing the powerhead in a powerhead compartment, wherein the top cowl can be opened or removed from the outboard motor to provide access to the powerhead from above the outboard motor;
- a first cooling system comprising a first pump configured to circulate a first cooling fluid through the outboard motor;
- a second cooling system comprising a reservoir configured to contain a second cooling fluid and a second pump configured to pump the second cooling fluid to cool at least one component of the outboard motor;
- and
- a heat exchanger configured to exchange heat between the first cooling fluid and the second cooling fluid to cool the at least one component of the outboard motor;
- wherein the first pump and the second pump are accessible from above the outboard motor upon opening and/or removal of the top cowl.
