Rather than replacing an entire shore power inlet, boat owners and marine electricians can swap out just the internal connector assembly when the interior contacts or components wear out or become damaged from repeated plugging and unplugging or from moisture exposure.\u003c\/p\u003e\u003cp\u003eThe 305CRMB features a male-to-female connector configuration built for 120 volt shore power systems, rated at 1250 watts, with a 2-conductor, 3-prong locking design that matches the original 303-series inlet housing. The interior is constructed from black plastic material for durability in a marine environment, and it is sized to drop into the existing 303SSEL-B and 303SSEL-BRV inlet housings without needing to replace the outer enclosure.\u003c\/p\u003e\u003cp\u003eThis part ships as a single replacement interior unit, allowing for a straightforward repair rather than a full inlet replacement, which saves on both parts cost and installation time.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Marinco\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 305CRMB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible With:\u003c\/strong\u003e 303SSEL-B, 303SSEL-BRV (303 3-Wire Locking Power Inlets)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Gender:\u003c\/strong\u003e Male-to-Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 120 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage:\u003c\/strong\u003e 1250 watts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Conductors:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Cord Prong Count:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 6.9 inches L x 5.7 inches W x 2.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.25 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMarinco 303SSEL-B 3-wire locking power inlet\u003c\/li\u003e\n\u003cli\u003eMarinco 303SSEL-BRV 3-wire locking power inlet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Marinco 305CRMB used for?\u003c\/strong\u003e The Marinco 305CRMB is a replacement interior for 303 3-wire locking power inlets, letting you replace the internal connector assembly of the inlet without swapping the entire unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich inlets does the 305CRMB fit?\u003c\/strong\u003e The 305CRMB is designed to fit the Marinco 303SSEL-B and 303SSEL-BRV 3-wire locking power inlets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage and wattage is the 305CRMB rated for?\u003c\/strong\u003e It is rated for 120 volts and 1250 watts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many conductors and prongs does this interior have?\u003c\/strong\u003e The 305CRMB has 2 conductors and a 3-prong locking configuration, matching the original 303-series inlet design.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 305CRMB?\u003c\/strong\u003e The replacement interior is black.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 305CRMB made from?\u003c\/strong\u003e It is made from plastic, matching the case material used in the original 303 series power inlet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 305CRMB package?\u003c\/strong\u003e The packaged part measures 6.9 inches long by 5.7 inches wide by 2.5 inches high.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 305CRMB weigh?\u003c\/strong\u003e The 305CRMB weighs 0.25 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the connector male or female?\u003c\/strong\u003e The 305CRMB has a male-to-female connector gender configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to replace the whole inlet housing to install the 305CRMB?\u003c\/strong\u003e No, the 305CRMB is just the interior connector assembly, meant to be installed into an existing 303SSEL-B or 303SSEL-BRV inlet housing rather than replacing the full unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 305CRMB an authentic Marinco part?\u003c\/strong\u003e Yes, the 305CRMB is a genuine Marinco part, manufactured by Marinco for use in its 303 series 3-wire locking power inlets.\u003c\/p\u003e","brand":"Marinco","offers":[{"title":"Default Title","offer_id":49025306099931,"sku":"MAR-305CRMB","price":33.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/305CRMB__42511.1722351906.500.750.jpg?v=1785165051","url":"https:\/\/www.goodvibesmarina.com\/products\/marinco-305crmb-replacement-interior-for-303-3-wire-locking-power-inlets-303ssel-b-303ssel-brv","provider":"Good Vibes Marina","version":"1.0","type":"link"}
