The PTFE additive reduces friction at moving contact surfaces, and the extreme-pressure additives are suited to the high-load, water-exposed applications common in marine propulsion and steering systems. This is the 8 oz \/ 227 g squeeze tube format — the most common package for routine maintenance and single-component service.\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Applications\u003c\/h3\u003e\n\u003cp\u003eMercury specifies 2-4-C for general-purpose external lubrication of:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePropeller shafts\u003c\/li\u003e\n  \u003cli\u003eSteering cables and linkages\u003c\/li\u003e\n  \u003cli\u003eThrottle and shift cables and linkages\u003c\/li\u003e\n  \u003cli\u003eRemote-control mechanisms\u003c\/li\u003e\n  \u003cli\u003eSwivel pins and hinge pins\u003c\/li\u003e\n  \u003cli\u003eTilt-lock mechanisms and tilt tubes\u003c\/li\u003e\n  \u003cli\u003eOutboard motor swivel bracket and tilt pivot points\u003c\/li\u003e\n  \u003cli\u003eBoat-trailer wheel bearings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAlways confirm the correct lubricant specification in the applicable Mercury service or owner’s manual before applying to any component.\u003c\/p\u003e\n\n\u003ch3\u003eImportant Compatibility Notice\u003c\/h3\u003e\n\u003cp\u003e2-4-C is a \u003cstrong\u003egeneral-purpose external marine grease\u003c\/strong\u003e and is not Mercury’s answer for every lubrication point.

The 8 oz tube is the right size for individual component service or keeping in a toolbox. The most common misapplication is using 2-4-C on gimbal bearings or U-joints, where Mercury specifies a dedicated grease. If the service manual calls for a specific product and it’s not 2-4-C, don’t substitute — the right lubricant matters on those components.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563871928356,"sku":"802859A1","price":22.59,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/4bfa0658-e04c-4af6-bbab-4044db2e0649.png?v=1789423863","url":"https:\/\/marisolmarine.com\/products\/merc-521","provider":"Marisol Marine Company","version":"1.0","type":"link"}
