POWERFUL & RELIABLE ENGINE: This 420cc 4-stroke horizontal shaft gas engine delivers up to 15 HP, with a maximum torque of 18.45 ft-lbs at 2,500 RPM and a top speed of 3,800 RPM. It features a 1.2-gallon fuel tank and is engineered to meet and exceed industrial-grade quality standards for dependable, long-lasting performance. Note: Engine ships dry—please add gasoline and engine oil (not included) before starting.
SHAFT & MOUNTING SPECIFICATIONS: The crankshaft measures 1" in diameter and 3.48" in length, with a 3/8"-24 UNF tapped end and a 1/4" keyway. Mounting pattern: 7.72" (L) x 3.39" (W) – 4.06" (W). The engine runs smoothly and quietly, and supports Torch F6TC spark plugs with a gap of 0.027"–0.031". Compatible with unleaded gasoline (minimum 87+ octane, ethanol content <10% recommended).
SAFE & VERSATILE OPERATION: Equipped with a forced air-cooling and splash lubrication system to maintain optimal operating temperature and safety during extended use. A built-in low oil shutdown sensor protects the engine from damage due to insufficient lubrication. Ideal for a wide range of equipment including cement mixers, compressors, log splitters, water pumps, tillers, mowers, vacuums, and more.
EXCELLENT REPLACEMENT OPTION: This engine is a reliable replacement for popular models such as Honda GX340/GX390 (389cc), Briggs & Stratton GX340/GX390 (389cc), Kohler CH440/ECH440/ECH440LE (429cc), and Yamaha MZ360/MX360/MX400 (357–402cc).
IMPORTANT NOTE: EPA compliant. Each engine is oil-tested before packaging to ensure quality, so you may notice slight oil residue. Rest assured, your engine is 100% brand new and ready for use once properly fueled and oiled.
