Oil is the lifeblood of your Mercury® outboard engine. Changing it along with the filter is a simple maintenance procedure that should be performed after every 100 hours of engine operation or at least once a year. Many boaters incorporate the job in their annual winterization process or before off-season storage to ensure their outboard is ready to perform at the beginning of the next season.
Changing the oil in a Mercury outboard is a simple process for the average do-it-yourself boat owner. This article outlines the step-by-step procedure for most Mercury outboard models. The oil change procedure, along with the specific engine oil requirements for every model, is also outlined in your Mercury operation and maintenance manual. If you don’t have a copy, you can download one from the Mercury website.
It’s important to use the correct type and volume of oil as outlined in your engine’s operation and maintenance manual. Quicksilver four-stroke marine engine oils are available in a complete range of grades and in mineral, synthetic blend and full synthetic formulations to meet or exceed the engine oil requirements of all Mercury outboards, as well as engines from other leading marine engine manufacturers. Quicksilver oil features additive packages formulated specifically to protect marine engines from wear and corrosion during use in harsh environments. Developed with the rigorous testing of an original-equipment engine manufacturer, Quicksilver oil provides performance, protection and peace of mind in every bottle.
Designed to maintain maximum oil flow rate and featuring high pleat counts for superior filtration levels, Quicksilver oil filters are the highest quality available for marine engine use and are available to fit all models of Mercury outboards. Quicksilver oil filters feature heavy-duty canisters that won’t leak, collapse or burst and an internal anti-corrosion coating that helps prevent the formation of rust or flaking that can block oil passages in the crankcase.
To make it even easier to assemble exactly what you need for your next oil change, Quicksilver oil change kits are available for most Mercury outboard models. Each kit includes the appropriate filter and volume of oil, a drain plug seal, an oil drain funnel and instructions.
Changing the oil and filter requires minimal tools. You’ll need:
Drain the oil
Replace the Filter
Add Fresh Engine Oil
Pro Tip: Check for Contamination
Always inspect your engine oil for signs of water or fuel contamination. Oil contaminated with water will have a milky color. Oil contaminated with fuel will have a strong odor of gasoline. If either sign is present, consult a Mercury Authorized Dealer.
That’s all there is to it. Protecting your engine – and your peace of mind – is as simple as following these basic steps and incorporating regular oil changes using high-quality Quicksilver marine lubricants and filters into your outboard maintenance schedule.
