{"title":"Mercury Outboard Cooling Systems","description":"\u003cp\u003eMost newer Mercury Marine outboard engines use an enclosed cooling system. This means that there is a small tank on the top of the engine that uses a combination of fresh water and coolant.\u003c\/p\u003e\n\u003cp\u003eThis fresh water is circulated through the engine and through a heat exchanger. The fresh water, in this system, absorbs the heat of the engine. Mercury outboard motors are typically designed as open loop cooling systems. Meaning the motor draws water from the host body. That water is circulated through the engine, and fuel pump to maintain prop engine temperatures. After passing through the engine or fuel pump the water is then dumped back into the host body. Water is drawn into the water pump through the intake opening of the lower unit, where it passes through a cavity that ends up entering the pump itself. At that point, the impeller pressures the water into the long inlet tube leading to the bottom side of the powerhead. Internal combustion engine cooling uses either air or liquid to remove the waste heat from an internal combustion engine. For small or special-purpose engines, cooling using air from the atmosphere makes for a lightweight and relatively simple system. Cooling system, apparatus employed to keep the temperature of a structure or device from exceeding limits imposed by needs of safety and efficiency.\u003c\/p\u003e\n\u003cp\u003eWater is inducted through the lower unit by a water pump impeller in the cooling system on an outboard and then forced upward to circulate throughout the powerhead, and eventually exits through the exhaust system.\u003c\/p\u003e","products":[{"product_id":"flush-m-mercury-outboard-flushing-solution-75-450hp-models","title":"Flush-M - Mercury Outboard Flushing Solution - Black - 75-450HP Models","description":"\u003cp\u003eThe Flush-M permanently replaces the OEM flush plug, making engine flushing quick and easy so you can spend more time on the water.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"Apple-converted-space\"\u003eThe Flush-M is specifically designed to permanently replace the OEM flush plug with the part number #22-888958001 found on late model Four Stroke Mercury Outboard Engines.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"Apple-converted-space\"\u003eIts unique features simplify repetitive engine flushing and is a must-have for single and multiple-engine boats alike.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cstrong\u003e\u003cspan class=\"Apple-converted-space\"\u003eFlush-M is compatible with Verado, Pro XS, FourStroke, and SeaPro series engines in all HP ratings from 75HP - 450HP.\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFlush-M have integrated \"Seasonal Solutions' for users in both warm and freezing climates.\u003cbr\u003e\u003cbr\u003eFlush-M significantly simplifies routine engine flushing, whilst exhibiting itself attractively on single and multiple engine boats.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eDimensions\u003c\/p\u003e\n\u003cp\u003e-H: 54.82 mm\u003cbr\u003e-W: 53.17 mm\u003cbr\u003e-L: 43.19 mm\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 16px;\"\u003e\u003cstrong\u003eFlush-M FAQ's\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is Flush-M different to a Gardena?\u003c\/strong\u003e\u003cem\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/em\u003eMost noticeably, the Flush-M takes the universal practicality of a quick connect and merges it with an accurately engineered base that cams perfectly securing itself to the Mercury outboard engine cowling.
