The oil pan forms the lower section of the engine crankcase, serving as the reservoir for engine oil and the base of the lubrication system. An OEM replacement ensures correct fitment, proper oil capacity, and a leak-free seal at the gasket mating surface — critical on a marine engine where an oil leak can mean oil in the bilge.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMercury MerCruiser engines where part number 8M0150300 appears on the engine parts diagram\u003c\/li\u003e\n\u003cli\u003eVerify fitment using your engine model number and serial number against the Mercury MerCruiser parts diagram before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eOil pan fitment is engine-family and serial-number specific.

A failed repair at sea means oil loss, engine damage, and potential oil in the bilge. Replacement with an OEM pan is the correct solution.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a new gasket when replacing the oil pan?\u003c\/strong\u003e\u003cbr\u003e\nYes, always. The oil pan gasket is a single-use component. Reusing the old gasket after disturbing the joint will result in an oil leak. Order the correct Mercury gasket set for your engine at the same time as the pan.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I find the right oil pan for my MerCruiser?\u003c\/strong\u003e\u003cbr\u003e\nUse your engine serial number and model number to look up the parts diagram. The oil pan part number is listed in the lubrication\/sump section. If you’re unsure, contact us with your serial number and we can help identify the correct part.\u003c\/p\u003e\n\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e This is the right part for a MerCruiser engine that has suffered impact damage to the oil pan — a very common scenario on sterndrives that have struck bottom or debris. It’s also the correct choice during a full engine rebuild where the original pan is corroded, warped, or has damaged drain plug threads beyond repair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon mistakes:\u003c\/strong\u003e The most frequent error is ordering an oil pan by engine displacement alone without checking the serial number — MerCruiser used multiple oil pan configurations across the same engine family depending on transom angle, mounting, and production year. Also watch for customers who order the pan but forget the gasket set; always recommend ordering both together to avoid a second service visit.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563921965092,"sku":"8M0150300","price":675.37,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/7eff72e3-ad2f-4805-a28f-ca09046f0e68.png?v=1787258425","url":"https:\/\/marisolmarine.com\/products\/merc-1257","provider":"Marisol Marine Company","version":"1.0","type":"link"}
