MerCruiser Oil Drain Screws

MerCruiser Oil Drain Screws

NuWave Marine carries MerCruiser oil drain screws, oil drain plugs, and other premium replacement parts to prevent leaks in your engine and keep your boat performing at peak levels.

Along with engine and bearing grease, oil is essential for lubricating moving parts. This reduces friction, prevents wear, lowers operating temperature, and allows your motor to do what it does best: power your boat around the water. You’ll need to keep your oil clean by checking your oil filter and changing your oil at regular intervals, and you’ll need to keep it from leaking out with an oil drain plug.

MerCruiser 5.7 Oil Drain Plug Size

Different MerCruiser engines may need different sizes of screws. If you need help figuring out what the MerCruiser 3.0 oil drain plug size is, for example, you should contact one of our helpful team members today. Since removing the drain screw is part of changing your MerCruiser marine oil, it’s recommended that you inspect it every time you change your oil. If you notice even a small imperfection in your screw, it can’t hurt to replace it. After all, buying a new drain screw is far cheaper than buying a new engine.
