A marine propulsion system includes an internal combustion engine; a fuel reservoir; a pump that pumps fuel from the fuel reservoir to the internal combustion engine; and a fuel filter that filters the fuel. The fuel filter includes a canister and a fuel inlet that conveys the fuel adjacent to cylindrical sidewalls of the canister so that the fuel immediately spirally flows around and down the cylindrical sidewalls under centrifugal force and under force of gravity, and then is drawn radially inwardly through a filter element by the pump. A fuel outlet extends at least partially along a center axis of the canister and discharges the fuel from the canister. A drain is located at the bottom of the canister and configured to drain water that separates from the fuel as the fuel flows around and down the cylindrical sidewalls.

Marine propulsion systems and fuel filters for marine propulsion systems

A filter for a water cooling system in a marine drive includes a cavity having an upper side and a lower side, a water inlet that delivers a water flow into the cavity, and a water outlet that delivers water out of the cavity. The flow velocity of water within the cavity is low such that heavy debris sinks toward the lower side of the cavity and buoyant debris floats toward the upper side of the cavity. An upper debris outlet expels the buoyant debris out of the cavity and a lower debris outlet expels the heavy debris out of the cavity.

Water cooling system for marine drive

A cooling system for a marine engine has a cooling jacket disposed in thermal communication with a heat-emitting portion of the marine engine. The cooling jacket has a water inlet, and a water outlet on an upper portion of the cooling jacket. A pump is connected in fluid communication with the water inlet and/or the water outlet that causes water to flow through the cooling jacket in order to cool the heat-emitting portion, wherein a flow velocity of water in the cooling jacket is low such that debris sinks to a lower portion of the cooling jacket. A debris outlet is in the lower portion of the cooling jacket that expels the debris from the cooling jacket.
