| Number | Title | Issue Date |
| 7318396 | Cooling system for a marine propulsion engine A cooling system for a marine engine incorporates first and second thermally responsive valves which are responsive to increases in temperature above first and second temperature thresholds, respectively. The two thermally responsive valves are configured in serial ... | 01/15/2008 |
| 7255069 | Cylinder sleeve support for an internal combustion engine The disclosed multi-cylinder, poppet-valved engine, has replacement cylinder sleeves larger than the original sleeves, and laterally supported near their upper ends by an aluminum alloy plate having a continuous flange or boss projecting into the cylinder block. The... | 08/14/2007 |
| 7094118 | Heat exchanger for a marine propulsion system The heat exchanger for a marine propulsion system is located within available space in front of the transom of a marine vessel and attached to the transom. The housing of the heat exchanger can be attached to a drive unit support structure and spaced apart from an e... | 08/22/2006 |
| 7000584 | Thermally insulated cylinder liner An engine is provided with a plurality of cylinders and cylinder liners that are shaped to define a plurality of spaces between the liners and the engine block. These spaces provided an insulative barrier that at least partially restricts the flow of heat from the l... | 02/21/2006 |
| 6223702 | Internal combustion engine In an internal combustion engine comprising an engine block consisting of a crankcase, at least one cylinder sleeve extending from the crankcase and a coolant jacket disposed around the cylinder sleeve or sleeves and a cylinder head mounted on the engine ... | 05/01/2001 |
| 5150668 | Cylinder liner with coolant sleeve Cylinder liners of internal combustion engines must be adequately cooled to obviate oil degradation, carbon packing in the ring area, and piston seizure. The engine includes a block which cooperates with the cylinder liners to define an upper and lower ax... | 09/29/1992 |
| 4667635 | Helical spring forming cooling channel around liquid-cooled cylinder The helical cooling channel in the cooling gap between the cylinder pipe and the associated cylindrical part of the housing and internal combustion engine is formed by a helical spring which is fixed in the cooling gap under radial tension. The helical sp... | 05/26/1987 |
| 4306614 | Heat exchanger for marine propulsion engines A heat exchanger is provided for a pressurized, closed cooling system for a marine propulsion engine. The heat exchanger includes a closed spiral passageway means for the fresh cooling water drawn from the lake or other water body. An outer housing enclos... | 12/22/1981 |
| 4220121 | Heat exchanger for marine propulsion engines A heat exchanger is provided for a pressurized, closed cooling system for a marine propulsion engine.
