When injectors fail on these engines, you'll experience rough running, misfires, excessive smoke, hard starts, and reduced power output — issues that are especially critical at sea. This 4-piece brand-new aftermarket injector set covers all four cylinders in a single order, with four cross-reference part numbers confirmed across Yanmar OEM and YM-prefix numbering formats, precision-matched to OEM spray pattern and injection pressure for the 4JH3 marine engine family.\u003c\/p\u003e\n\n\u003ch3\u003e✅ Direct-Fit Compatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eYanmar Marine Engines:\u003c\/strong\u003e 4JH3-DTE, 4JH3-HTE\u003c\/li\u003e\n  \u003cli\u003eSuitable for sailboats and motorboats fitted with the Yanmar 4JH3 series engine\u003c\/li\u003e\n  \u003cli\u003eBolt-on replacement — no modifications required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e🔧 Product Highlights\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% Brand New Aftermarket:\u003c\/strong\u003e Not rebuilt or refurbished — starts with a full service life\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM-Spec Fuel Atomization:\u003c\/strong\u003e Precise spray pattern for clean combustion, restored power, and reliable operation at sea\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete 4-Cylinder Set:\u003c\/strong\u003e Full engine coverage in a single order — no need to source injectors individually\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4 Cross-Reference Part Numbers:\u003c\/strong\u003e Covers Yanmar OEM and YM-prefix formats for confirmed fitment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrevents Cascading Failures:\u003c\/strong\u003e Replacing all four eliminates future unplanned downtime from remaining worn injectors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMarine-Critical Reliability:\u003c\/strong\u003e Consistent fuel delivery across all cylinders for dependable power when it matters most\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e📦 What's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4 × Fuel Injectors (729672-53100)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e🔑 Key Specs\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e 729672-53100, YM729672-53100, 72967253100, YM72967253100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e 100% New Aftermarket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 4 pieces (complete 4-cylinder set)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yanmar 4JH3-DTE \/ 4JH3-HTE marine engines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003ePlease verify your engine serial number and existing part number before ordering.
