To change the lower gear oil in your outboard, first locate the drain plug on the lower unit and remove it. Next, use a pump or turkey baster to remove the old oil from the lower unit. Finally, refill the lower unit with new gear oil and replace the drain plug.
- Remove the oil cap from the lower gearcase
- Insert a small funnel into the opening and pour in the recommended amount of new oil
- Replace the oil cap and screw it on tightly
- Start the engine and let it run for a few minutes to distribute the new oil throughout the system
- Shut off the engine and check for leaks around the gearcase
How Often Do You Change the Lower Unit Oil on an Outboard Motor?
How often you should change the lower unit oil on your outboard motor depends on a few factors. These include the make and model of your motor, how often you use it, and what type of water you typically use it in. Generally speaking, most experts recommend changing the oil every 50 to 100 hours of use, or once a year – whichever comes first.
If you boat in saltwater more frequently than fresh, it’s a good idea to change the oil more frequently as well. And if you don’t use your outboard very often, it’s still important to change the oil at least once a year to keep things running smoothly.
How Do You Change the Lower End Oil on an Outboard Motor?
Assuming you have a basic understanding of boat motors, this blog will outline how to change the lower oil on an outboard motor. This process is pretty similar for most boat makes and models, but always check your owner’s manual before starting any work on your motor.
First, you’ll need to gather a few supplies: a clean container to catch the old oil, new oil (the amount will be specified in your owner’s manual), a funnel, and rags.
You might also want gloves and eye protection.
Once you have everything gathered, locate the drain plug on the lower unit of your outboard motor. The location will vary depending on the make and model of your motor, but it is usually near the back of the unit.
Remove the drain plug with a wrench and let all of the old oil drain into your container. Once it has drained completely, replace the drain plug and tighten it securely.
Now it’s time to add new oil to the lower unit.
Using your funnel, pour new oil into the fill hole until it reaches the level specified in your owner’s manual. Once you’ve added enough oil, replace the fill cap/screw and tighten it securely. Wipe up any spills with a rag and dispose of all used oils properly – never pour them down a drain!
That’s it! You’ve successfully changed the lower end oil on your outboard motor. Be sure to run through a quick checklist (included in most owner’s manuals) before taking your boat out again to ensure everything is in working order.
How Much Oil Does a Outboard Lower Unit Hold?
An outboard lower unit typically holds between 1 and 4 quarts of oil. The amount of oil that your particular lower unit requires will depend on the make and model of your engine. You can usually find this information in your engine’s owner’s manual.
If you are changing the oil in your lower unit for the first time, it is important to note that you may need to add oil to the lower unit before starting the engine. This is because some of the oil will be drained out when you remove the old oil plug. Consult your owner’s manual for specific instructions on how to do this.
How Often Should You Change Lower Gear Oil?
If you have a manual transmission, it’s recommended that you change your lower gear oil every 30,000 to 60,000 miles. If you have an automatic transmission, it’s recommended that you change your lower gear oil every 50,000 to 100,000 miles.

Changing Lower Unit Oil Mercury 2-Stroke
If you own a Mercury 2-stroke outboard, it’s important to change the lower unit oil regularly. This keeps the gears and bearings lubricated, prevents corrosion, and helps cool the engine. Here’s a step-by-step guide to changing the oil in your Mercury 2-stroke outboard’s lower unit:
1. Start by draining the old oil. Remove the drain plug from the side of the lower unit and let all of the old oil drain into a catch pan. Once it’s all drained, replace the drain plug.
2. Next, remove the fill plug from the front of the lower unit and slowly pour in new oil until it starts to drip out of the fill hole. Replace the fill plug when you’re finished adding oil.
3. Finally, start up your engine and check for leaks around both plugs.
If everything looks good, you’re done!
Marine Lower Unit Gear Oil
What is Marine Lower Unit Gear Oil?
Marine lower unit gear oil is a specialized lubricant designed for use in the gearboxes of marine vessels. Unlike standard automotive oils, marine gear oil is formulated to resist the effects of water and corrosion, making it ideal for use in saltwater environments.
Marine gear oil also typically contains additives that help to reduce wear and protect against damage from high loads or shock-loading.
Why is Marine Lower Unit Gear Oil Important?
Proper lubrication is essential for the proper functioning of any mechanical system, and the gears in a marine vessel’s lower unit are no exception.
Marine gear oil helps to keep these gears properly lubricated while also protecting them from the corrosive effects of saltwater. Without this specialized oil, your vessel’s lower unit could be at risk of serious damage.
How Often Should I Change My Marine Lower Unit Gear Oil?
The frequency with which you’ll need to change your marine lower unit gear oil will vary depending on how often you use your vessel and the conditions in which it operates. In general, however, it’s a good idea to change your lower unit gear oil at least once per year or every 50 hours of operation, whichever comes first. If you frequently operate your vessel in harsh conditions or heavy seas, you may need to change your gear oil more often.
Consult your owner’s manual or a qualified marine mechanic for specific recommendations.
How to Change Lower Unit Oil
It’s important to change the lower unit oil in your boat or outboard motor on a regular basis – at least once a year, and more often if you use it frequently. This simple maintenance task will keep your engine running smoothly and prolong its life. Here’s how to do it:
1. Place your boat on a level surface and remove the drain plug from the lower unit. Let the oil drain into a pan for disposal.
2. Once the oil has drained completely, replace the drain plug and fill the lower unit with fresh oil, using a funnel if necessary.
The amount of oil you need will vary depending on the make and model of your engine – consult your owner’s manual for specific instructions.
3. Start the engine and let it run for a few minutes to circulate the new oil before checking for leaks around the drain plug and filling hole. If everything looks good, put your boat back in storage or head out onto the water!
Lower Unit Gear Oil Pump
As most boat owners know, there are many moving parts located in the lower unit of an outboard motor. One of these vital components is the gear oil pump. The gear oil pump circulates lubricating oil throughout the gears and bearings, reducing friction and keeping everything running smoothly.
Like any other mechanical component, the gear oil pump can eventually fail. When this happens, it’s important to replace it as soon as possible to avoid damage to the engine. In this blog post, we’ll discuss how to identify a failed gear oil pump and what steps you need to take to replace it.
One common symptom of a failing gear oil pump is increased noise from the engine. If you notice that your engine is making more noise than usual, especially when idling, it’s a good idea to check the gear oil level. If it’s low, there’s a good chance that the pump isn’t working correctly and needs to be replaced.
Another symptom of a failing gear oil pump is leaking fluid. You may notice fluid leaking from around the base of the motor or dripping from underneath the boat. This is a sure sign that something is wrong with the pump and needs to be fixed ASAP.
If your boat is experiencing either of these symptoms, or if you simply suspect that the gear oil pump might be failing, follow these steps:
1) Remove The Lower Unit: This will give you access to inspect and/or replace thegear oilpump .
2) Inspect The Pump: Once you have access tothepump , visually inspect it for any signs of leaks or damage .

Conclusion
In order to change the lower gear oil in your outboard, you will need to first locate the drain plug. Once you have found the drain plug, use a wrench to remove it and allow the old oil to drain out. Next, clean off the area around the plug before replacing it.
Be sure to use new washers when putting the plug back in. Finally, fill up your outboard with fresh gear oil until it reaches the full line on the dipstick.
