4.3l Mercruiser Oil Change
I can give you instructions on how to change the oil in a 4.3L engine Mercruiser. Here is a step-by-step guide.
- Prepare the materials needed: you will need a fresh oil filter (the type and amount of oil recommended by your engine manual), an oil filter wrench or socket set, an oil drain pan, and gloves.
- Prepare the engine. Start by warming the engine up for a few moments to ensure that the oil flows smoothly. To prevent accidents, make sure that the boat is anchored or docked securely.
- Find the oil drain plug. The oil drain plug is usually located at the bottom of the engine oil pan. Place the oil pan underneath the engine to catch the old oil.
- Drain the old oil. Remove the drain plug using a socket wrench or a socket set. Let the old oil drain into the drain pan. Replace the drain plug after all the old oil has been drained. Tighten it.
- The oil filter is located usually near the pan of oil. Oil filter wrenches are used to remove and loosen the old oil filters. Carefully avoid spilling any oil. Apply a thin oil film to the rubber seal on top of the filter before installing the new one. After that, tighten the filter by hand. Use the oil filter wrench to tighten this filter additional three-quarters of a rotation.
- Find the oil fill cap or dipstick tube. It is usually located on top of the engine. Remove the cap and place it aside. Pour the amount of engine oil recommended into the engine using a funnel. Dipstick is a good way to check the oil level. Add more if needed. Do not overfill your engine.
- Remove the old oil and clean up any spills. Use rags, paper towels, or a rag to wipe off any oil. Be sure to tighten the oil filter and drain plug. You can dispose of your old oil filter and oil at an authorized recycling facility, or at an auto parts shop that accepts used oils.
- Double-check: Before you start the engine, check the oil filter and the drain plug. Make sure they are securely tightened. If necessary, clean up any oil that has remained.
That’s it! Your 4.3L Mercruiser engine is now ready for an oil change. Consult your engine’s manual if you need any specific recommendations or instructions.

I read somewhere in the Mercruiser manual that if an engine failure occurs due to non-Mercury spec oil, the warranty will be voided. What does everyone else run in their MerCruiser engines these days?
A high-quality marine engine oil that matches the standards indicated in your engine’s handbook is suggested. Typically, a multi-viscosity oil with a rating of 15W-40 or 20W-40 is suitable for the 4.3L Mercruiser engine.
No, it is not recommended to use automotive oil in a marine engine. Marine oils are specifically formulated to handle the unique demands of marine environments, including higher operating temperatures and increased moisture.
The oil change interval varies according to factors such as engine usage, operating conditions, and the kind of oil used. At least once a year, or every 50 to 100 engine hours, the oil should be changed.
It is generally best to avoid mixing different oil brands or viscosities unless specifically recommended by the oil manufacturer. Mixing oils with different formulations can affect their performance and may lead to inadequate lubrication.
The exact oil capacity can vary slightly depending on the specific engine model. To determine the correct oil capacity, refer to your engine’s manual. Typically, a 4.3L Mercruiser engine requires around 4-5 quarts (3.8-4.7 liters) of oil for an oil change.
It is recommended to use a high-quality oil filter that is designed for marine engines and compatible with your 4.3L Mercruiser engine model. Consult your engine’s manual or a trusted marine retailer to ensure you select the correct oil filter.
It is best to check the oil level when the engine is off. This allows the oil to settle back into the oil pan, providing a more accurate reading on the dipstick.
It is not recommended to reuse oil filters. To guarantee effective filtration and engine protection, it is recommended practice to replace the oil filter with a new one at each oil change.
