It is engineered to replace multiple original equipment (OE) part numbers and aftermarket equivalents so you can repair leaks, restore proper float operation and refresh worn seals without buying a full carburetor. The kit fits common early- and mid-era models across the 6, 8, 9.9, 10, 15, 20 and 25 horsepower ranges.\u003c\/p\u003e\n\n\u003ch3\u003eWhich Mercury and Mariner engines will this rebuild kit work with?\u003c\/h3\u003e\n\u003cp\u003eThis kit is matched to a list of Mercury\/Mariner outboards identified by their horsepower and serial start points.

It’s ideal when the carburetor body is structurally sound but the internal consumables are worn, leaking or causing fuel level problems. Use it when you need an affordable way to restore reliable handling and stop fuel-related issues common on older 6–25 HP outboards.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this kit fit my 9.9 HP Mercury model?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it fits 9.9 HP Mercury\/Mariner models from serial 0A197112 and later.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this kit fix a cracked carburetor bowl?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — it replaces seals and needles; a cracked bowl needs a replacement carburetor.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MOTOALL","offers":[{"title":"Default Title","offer_id":48084496384158,"sku":"B0BD8H1J1R","price":31.38,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/motoall-carb-rebuild-kit-front-packaging.jpg?v=1785857435","url":"https:\/\/northtrailauto.ca\/products\/motoall-carburetor-rebuild-kit-for-mercury-mariner-6-25-hp-gaskets-needles-o-rings","provider":"North Trail Auto","version":"1.0","type":"link"}
