At high RPMs, high water pump pressure forces the valve open, bypassing the thermostat to dump excess water volume and prevent over-pressurisation or blown gaskets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Compatibility:\u003c\/strong\u003e Fits midrange and large Suzuki 4-stroke outboard motors across several decades:\u003cul\u003e\n\u003cli\u003eDF90 (2001–2008)\u003c\/li\u003e\n\u003cli\u003eDF100 \/ DF100A (2009–2017)\u003c\/li\u003e\n\u003cli\u003eDF115 \/ DF115A (2001–2020)\u003c\/li\u003e\n\u003cli\u003eDF140 \/ DF140A (2002–2020)\u003c\/li\u003e\n\u003cli\u003eDF150 \/ DF150A (2006–2020)\u003c\/li\u003e\n\u003cli\u003eDF175 \/ DF175A (2006–2020)\u003c\/li\u003e\n\u003cli\u003eDF200 \/ DF200A (2015–2020)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDiagnostic Relevance\u003c\/h3\u003e\u003cp\u003eIf your outboard runs completely fine at low idle speeds but throws a \u003cstrong\u003e“Hot” or overheating warning alarm as soon as you accelerate\u003c\/strong\u003e past 2,500–3,000 RPM, this poppet valve is the primary culprit. Salt crust, sand, or small pieces of debris from a degraded impeller can wedge the valve stuck.
