The stator is the stationary charging\/ignition component mounted around the flywheel that generates the electrical signal used by the ignition system, and a failed or weak stator is a common cause of no-spark or intermittent-spark conditions on these outboards. This unit is constructed of metal with a white finish and is built to meet or exceed the output and fit of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003eFitment is engine-specific by serial number range: it fits Mercury 65 (650) HP 3 cylinder outboards in the 4382057 to 4571651 serial number range, and Mercury 70 HP 3 cylinder outboards in the 4571652 to A996141 serial number range. Confirm your outboard's horsepower, cylinder count, and serial number before ordering, since stators are not interchangeable across engine families. The Sierra 18-5865 is a direct cross to several OEM and aftermarket part numbers, making it easy to identify against the number stamped on your old unit or listed in your parts manual.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-5865\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Outboard Motor Stator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Engine Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Horsepower:\u003c\/strong\u003e 70 Horsepower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282112103\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury 65 (650) HP, 3 cylinder, serial number range 4382057 to 4571651\u003c\/li\u003e\n\u003cli\u003eMercury 70 HP, 3 cylinder, serial number range 4571652 to A996141\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMallory 9-25506\u003c\/li\u003e\n\u003cli\u003eMercury 398-5704A7\u003c\/li\u003e\n\u003cli\u003eMercury 398-5704A2\u003c\/li\u003e\n\u003cli\u003eMercury 398-5704A5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5865 stator fit?\u003c\/strong\u003e It fits Mercury 65 (650) HP 3 cylinder outboards in the 4382057 to 4571651 serial number range, and Mercury 70 HP 3 cylinder outboards in the 4571652 to A996141 serial number range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5865 the same as the Mercury 398-5704A7 stator?\u003c\/strong\u003e Yes, the Sierra 18-5865 is a direct cross reference to Mercury 398-5704A7, as well as to Mercury 398-5704A2, Mercury 398-5704A5, and Mallory 9-25506.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this stator weigh?\u003c\/strong\u003e The Sierra 18-5865 stator weighs 3.02 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the stator made from?\u003c\/strong\u003e It is constructed of metal with a white finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my Mercury outboard needs a new stator?\u003c\/strong\u003e A failing stator commonly causes no-spark or intermittent-spark conditions;
