A clear plastic or glass container is helpful to dump the filter and examine the contents. A small amount of debris is common, as is a small amount of water after the fuel has had a moment to settle.

The scope of this service will only include the low-pressure fuel filter and fuel water separator if applicable by model. Mercury recommends that owners do not service their high-pressure fuel filters. Depending on your engine model, the water separator filter (or castle filter) may be removed by using a wrench, standard tools, and a little caution. Unplug the water-in-fuel sensor if applicable and spin the cap off of the housing. Replace the filter element with a fresh one, lube the o-ring with grease or oil, and carefully reinstall the cap.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan\u003eLocate your Mercury engine’s primer bulb if applicable and use the primer to pump up the fuel system.

The standard dose is one ounce per ten gallons, but if you are not running the product regularly, you can double that ratio for more cleaning power. Pour the products into the fuel tank fill and run the boat. No additional work is needed. It is a great idea to inspect your fuel tank fill’s o-ring for damage when you add fuel or additives as a damaged o-ring can allow water from rain or boat washing into your fuel system.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003ch3\u003e\n\u003cstrong\u003eHow do I perform an oil change on my \u003c\/strong\u003e\u003ca href=\"https:\/\/partsvu.com\/blogs\/boating-resources\/mercury-2-stroke-oil-service-100-hour-service-step-1\"\u003e\u003cstrong\u003eMercury 2-stroke outboard motor\u003c\/strong\u003e\u003c\/a\u003e\u003cstrong\u003e?\u003c\/strong\u003e\n\u003c\/h3\u003e\n\n\u003cp\u003e\u003cspan\u003eEngine oil selection is critical to long life, so review the information in your owner’s manual to make certain you are using the correct products.
