The oil that goes in an outboard lower unit is typically a 10W-30 or a 10W-40 motor oil. The oil should be changed every 50 hours of use or at the beginning of each season, whichever comes first.
If you’re a boat owner, chances are you’ve had to deal with a lower unit oil change at some point. Lower unit oil is vital to the proper function of your outboard motor, and it’s important to use the right type of oil in order to keep things running smoothly. So, what oil goes in an outboard lower unit?
There are actually several different types of oils that can be used in an outboard lower unit, depending on the make and model of your engine. However, most manufacturers recommend using a specialized outboard motor oil that is specifically designed for use in these engines. This type of oil typically contains additives that help protect against corrosion and wear, both of which can be major issues in saltwater environments.
While there are other oils that can technically be used in an outboard lower unit, it’s always best to play it safe and go with what the manufacturer recommends. After all, they know their products better than anyone else!
Can You Use Regular Gear Oil in an Outboard Lower Unit?
If you have an outboard motor, you may be wondering if you can use regular gear oil in the lower unit. The answer is yes, as long as it meets the specifications of your particular engine. Check your owner’s manual to be sure.
Gear oil helps to lubricate the gears and bearings in the lower unit and keep them running smoothly. If you use the wrong oil, it could damage the gears or cause premature wear.
What Kind of Oil Do You Put in an Outboard Gearbox?
There are a few different types of oil that can be used in an outboard gearbox, but the most common and recommended type is SAE 90 gear oil. This oil is specifically designed for use in gearboxes and will help to keep the gears lubricated and operating smoothly. Other oils that can be used include motor oil or ATF (automatic transmission fluid), but these are not as effective as SAE 90 gear oil and may cause premature wear on the gears.
What is the Best Oil for a Mercury Lower Unit?
There are a few different types of oil that can be used in a mercury-lower unit. The most common type of oil is gear oil, which is designed to lubricate gears and bearings. This type of oil is usually used in automotive applications, but it can also be used in outboard motors.
Another type of oil that can be used in a mercury-lower unit is synthetic oil. This type of oil is designed to provide better protection against wear and tear, and it can also help to improve fuel economy.
How Often Should You Change the Oil in the Outboard Lower Unit?
It is typically recommended to change the oil in your outboard lower unit every 100 hours of use or once a year, whichever comes first. However, if you use your boat frequently or in saltwater conditions, it is advisable to change the oil more often. When changing the oil, be sure to also check and clean the filter.

Johnson Outboard Lower Unit Oil Type
If you have a Johnson outboard, you may be wondering what kind of oil to use in the lower unit. There are actually two different types of oil that can be used, and it’s important to choose the right one for your engine.
The first type of oil is called gear lube, and it’s specifically designed for use in gear-driven engines.
This type of oil is thicker than standard motor oil, which helps to protect the gears from wear. Gear lube also has special additives that help to keep the gears clean and prevent corrosion. The second type of oil that can be used in a Johnson outboard is called 2-stroke engine oil.
This type of oil is thinner than gear lube, but it still provides excellent protection for the engine components. 2-stroke engine oil also has special additives that help to keep the engine clean and prevent corrosion. So, which type of oil should you use in your Johnson outboard?
If you’re not sure, it’s always best to consult your owner’s manual or an authorized dealer.
Outboard Lower Unit Oil Pump
The outboard lower unit oil pump is responsible for circulating oil through the engine and gears of your outboard motor. This pump is typically located near the bottom of the engine, beneath the waterline. The oil pump is usually driven by a gear on the crankshaft, and it has an internal check valve to prevent oil from flowing back into the crankcase when the engine is not running.
If your outboard lower unit oil pump fails, it can cause serious damage to your engine. It is important to check your lower unit oil level regularly and to change the oil and filter according to your manufacturer’s recommendations. A clogged or failed oil pump can also be caused by dirt or debris in the bottom of the boat, so be sure to keep your bilge clean.
Quicksilver Lower Unit Oil
Quicksilver lower unit oil is a premium quality, high-performance gear oil designed to provide optimum lubrication and protection for marine engines. Quicksilver has been the leader in marine lubrication technology for over 50 years and is trusted by boatbuilders and boaters around the world.
There are different types of oil that can be used in an outboard lower unit. The most common type of oil to use is called gear oil. This type of oil is designed to lubricate the gears inside the lower unit.
Gear oil typically has a higher viscosity than engine oil, which means it will stay in place better and provide more protection for the gears.
