It is molded from durable plastic with a machined finish and features a 3\/8 inch hose barb on one end to accept the tell tale hose and a 1\/8 inch NPT threaded connection on the other end for installation into the powerhead or pump housing fitting.\u003c\/p\u003e\u003cp\u003eThis elbow is designed for Johnson and Evinrude outboard applications and is a direct cross-reference for the OEM part it replaces, so it installs and functions the same as the original fitting. Its compact size and simple two-connection design make it an easy, low-cost replacement when the original elbow cracks, clogs, or breaks from age and vibration.\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 18-3566\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Barb Size:\u003c\/strong\u003e 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 1\/8 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type:\u003c\/strong\u003e NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Elbow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Johnson and Evinrude outboards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Johnson and Evinrude outboard applications that use a tell tale hose elbow fitting.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e331894\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3566 Tell Tale Hose Elbow do?\u003c\/strong\u003e It connects the tell tale indicator hose to the outboard's water pump discharge fitting, letting the operator see a stream of water while the engine runs to confirm the cooling system is pumping properly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat outboards is the 18-3566 elbow designed for?\u003c\/strong\u003e The 18-3566 elbow is designed for use in Johnson and Evinrude outboard applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-3566 replace?\u003c\/strong\u003e Sierra part 18-3566 replaces Johnson\/Evinrude OEM number 331894.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size hose barb does this elbow have?\u003c\/strong\u003e The 18-3566 elbow has a 3\/8 inch hose barb for connecting the tell tale hose.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size connects the elbow to the powerhead?\u003c\/strong\u003e It threads in with a 1\/8 inch NPT connection on the fitting end opposite the hose barb.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-3566 tell tale hose elbow made from?\u003c\/strong\u003e It is molded from plastic with a machined finish and a white color.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this part weigh?\u003c\/strong\u003e The Sierra 18-3566 Tell Tale Hose Elbow weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-3566 elbow?\u003c\/strong\u003e It measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3566 a genuine equivalent to the original equipment part?\u003c\/strong\u003e Yes, the 18-3566 is built to meet or exceed the original equipment part it replaces, part number 331894.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to replace this elbow?\u003c\/strong\u003e Replace the 18-3566 tell tale hose elbow if the original fitting cracks, clogs, or breaks, causing a weak or absent tell tale water stream.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-3566?\u003c\/strong\u003e The order includes one Sierra 18-3566 Tell Tale Hose Elbow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3566 elbow require any additional parts to install?\u003c\/strong\u003e No additional parts are required; the 3\/8 inch barb end accepts the existing tell tale hose and the 1\/8 inch NPT end threads directly into the mating fitting.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988153643227,"sku":"SIE-18-3566","price":6.34,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3566_lg__34842.1558124448.500.750.jpg?v=1785188941","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3566-tell-tale-hose-elbow-replaces-oem-331894-fits-johnson-evinrude-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
