Marine propulsion system with fuel line cooler
First Claim
1. In a marine propulsion system having a water-cooled internal combustion engine in a heat-retentive compartment, and including a fuel line in said compartment supplying fuel for combustion by said engine, fuel line cooler means in said compartment in heat transfer relation with said fuel line and having an inlet communicating with a source of cooling water and having an outlet for discharging water, wherein said fuel line cooler means comprises a water hose wound in a helical coil around said fuel line such that cooling water flowing through said helical coil hose cools said hose which in turn cools said fuel line.

Abstract
A fuel line cooler (34) is provided for a marine propulsion system (2) having a water cooled internal combustion engine (4) in a heat retentive compartment (5). The fuel line cooler (34) has an inlet (36) in communication with the source (14, 12) of cooling water for the engine (4), and has an outlet (38) for discharging water. The fuel line cooler (34) is cooled by sea water during running of the engine (4). Upon turn off of the engine (4), the cooled water in the fuel line cooler (34) is in heat transfer relation with the fuel and prevents vaporization and or spewing of the fuel.
