Its enhanced-cellulose filtration media removes abrasive contaminants from circulating engine oil, while the built-in anti-drainback valve helps retain oil in the filter during shutdown for faster lubrication at startup.\u003c\/p\u003e\u003cp\u003eThis long-format filter measures approximately 5.20 inches high by 3.66 inches in diameter and uses a 3\/4\"-16 mounting thread.

Ford-based marine engines may use different filter lengths or remote-filter configurations even when the engine displacement is the same. Do not select the filter by its 3\/4\"-16 thread alone — the gasket dimensions, bypass-valve pressure, anti-drainback-valve requirement, and physical clearance must also match the installed lubrication system.\u003c\/p\u003e\u003ch3\u003eWhen to Replace\u003c\/h3\u003e\u003cp\u003eReplace the oil filter whenever the engine oil is changed or at the interval specified by the engine manufacturer. More frequent replacement may be appropriate for engines exposed to extended trolling or low-speed operation, heavy loads and high operating temperatures, short or infrequent operating cycles, fuel dilution or moisture contamination, long periods of seasonal storage, or internal engine repairs. A dented, corroded, or leaking filter should be replaced immediately.\u003c\/p\u003e\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cp\u003eRemove the old filter and confirm its sealing gasket has not remained stuck to the mounting surface. Clean the filter head and lightly coat the new filter gasket with clean engine oil. Install by hand to the manufacturer’s tightening specification — do not overtighten. After installation: refill with the specified oil, start the engine and verify normal oil pressure, inspect the filter gasket and body for leakage, shut down and allow oil to settle, then recheck and correct the oil level. Ensure the longer filter body has adequate clearance from engine mounts, exhaust components, hoses, and the hull structure.\u003c\/p\u003e\u003ch3\u003eCross-Reference Numbers\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMotorcraft FL-1A\u003c\/li\u003e\n\u003cli\u003eFord D9AZ-6731-A\u003c\/li\u003e\n\u003cli\u003eNAPA Gold 1515\u003c\/li\u003e\n\u003cli\u003eFRAM PH8A\u003c\/li\u003e\n\u003cli\u003eBaldwin B2\u003c\/li\u003e\n\u003cli\u003eFleetguard LF3313\u003c\/li\u003e\n\u003cli\u003eDonaldson P550008\u003c\/li\u003e\n\u003cli\u003ePurolator L30001\u003c\/li\u003e\n\u003cli\u003eACDelco PF2\u003c\/li\u003e\n\u003cli\u003eSierra 18-7875-1\u003c\/li\u003e\n\u003cli\u003ePleasurecraft Marine R077001 \/ R-077001\u003c\/li\u003e\n\u003cli\u003eMerCruiser 60565 \/ 35-802886Q \/ 35-8M0116378\u003c\/li\u003e\n\u003cli\u003eOMC 502900 \/ 173231\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCross-reference numbers are comparison aids only.

Matching the existing filter number and measuring the available space usually prevents the most common fitment mistake. The extensive marine cross-reference list above — including MerCruiser, OMC, and PCM part numbers — makes this a useful starting point, but always verify against your specific engine serial number and marinizer before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada-wide shipping. ⚓\u003c\/p\u003e","brand":"NSP","offers":[{"title":"Default Title","offer_id":43563952373796,"sku":"51515","price":15.88,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/7b392313-7bc4-4de8-a833-53d8f962fb5a.png?v=1784311735","url":"https:\/\/marisolmarine.com\/products\/wix-oil-filter-51515-ford","provider":"Marisol Marine Company","version":"1.0","type":"link"}
