Find the Right Marine Oil Change Kit
An oil change kit makes it easier to gather the oil and service parts for a specific marine engine. This selection includes kits for four-stroke outboards, MerCruiser sterndrives, and select inboard engines. The right choice depends on the engine application, so check the kit’s fitment and contents before adding it to your cart.
Shop by Engine Manufacturer and Application
Maintaining a Mercury outboard? Browse our Mercury oil change kits to narrow the selection by engine family and horsepower. For a Yamaha four-stroke outboard, see our Yamaha oil change kits. You can also shop the products above for MerCruiser sterndrive and inboard oil change kits.
Some applications have more than one available kit, including options from Mercury, Yamalube, Quicksilver, and Sierra. Compare the product listings for compatible engines, included parts, and oil specifications before choosing.
What to Check Before Ordering an Oil Change Kit
Start with your engine make and model, then confirm its horsepower, engine family or displacement, and year or serial number where the listing specifies them. Horsepower alone may not identify the correct kit: different engine generations can use different filters, oil quantities, or service parts.
Next, review the contents of the individual kit. Many marine oil change kits contain engine oil and an oil filter. Depending on the application, a kit may also include a drain plug seal, gasket, funnel, drain hose, or instructions. Check the listing to see what is supplied and whether you need any additional tools or materials for your service.
Complete Your Engine Maintenance
If you already have some of the supplies you need, shop marine oil and oil filters separately. For help checking your engine’s oil requirements, read our marine engine oil capacity and maintenance guide.
An engine oil change and a gearcase lube change are separate service tasks on applicable outboards and sterndrives. Do not assume gear lube is included in an engine oil change kit. Our marine gear lube guide explains what to consider when planning that part of your maintenance.
Marine Oil Change Kit FAQs
How do I find an oil change kit that fits my boat engine?
Match your engine manufacturer, model, horsepower, and engine family to the fitment on the kit’s product page. Check the year or serial number when the listing calls for it. If two kits appear similar, compare their stated applications and contents before ordering.
What is included in a marine oil change kit?
Contents vary by product. Many kits include marine engine oil and an oil filter; some also include seals, gaskets, a funnel, or other service items. The individual product listing identifies what comes with that kit.
Can I use an outboard oil change kit for a sterndrive or inboard engine?
Only if the kit’s product listing specifically names your engine as a compatible application. Outboards, sterndrives, and inboards can have different oil capacities, filters, and oil specifications. Select a kit by its stated fitment rather than by the amount of oil in the package.
Does an oil change kit include lower-unit gear lube?
Not necessarily. An engine oil change kit is intended for engine oil service, while gearcase lube is a separate maintenance item for applicable outboards and sterndrives. Review the kit contents and purchase the specified gear lube separately if your service requires it.
