This fuse kit protects the charging circuit and is required on engines equipped with a Delco starter, identifiable by the round solenoid mounted directly to the starter. Engines fitted with a Prestolite starter using a remote solenoid do not require this fuse kit, so it is important to visually inspect the starter before ordering.\u003c\/p\u003e\u003cp\u003eSierra manufactures the 18-8220 to meet or exceed original equipment quality and specifications, giving boat owners a reliable replacement or upgrade option when servicing the charging system on covered Mercruiser engines. The kit carries a 90 amp current rating at 12 volts and is finished in white. It is sold separately from the alternator conversion kit itself and is compact, with each unit measuring approximately 0.39 x 0.39 x 0.39 inches and weighing 0.13 pounds.\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 18-8220\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuse Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 90 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Surface Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Mallory 9-15510, Mercruiser 88-79023A91\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercruiser 470 Series aluminum block engines, serial number 4625580 and up, with stator charging system and water cooled voltage regulator to alternator system\u003c\/li\u003e\n\u003cli\u003eMercruiser 224 \/ 3.7L\u003c\/li\u003e\n\u003cli\u003eRequired on engines with a Delco starter (round solenoid mounted to starter); not required on Prestolite starters with remote solenoid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMallory 9-15510\u003c\/li\u003e\n\u003cli\u003eMercruiser 88-79023A91\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-8220 fuse kit fit?\u003c\/strong\u003e The 18-8220 fits Mercruiser 470 Series aluminum block engines, serial number 4625580 and up, that use a stator charging system with a water cooled voltage regulator to the alternator, including the Mercruiser 224 \/ 3.7L.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this fuse kit required for every 470 Series alternator conversion?\u003c\/strong\u003e No. The Sierra 18-8220 fuse kit is only required on engines with a Delco starter, which has a round solenoid mounted directly to the starter.
