Assuming you have an outboard motor:
To start, you’ll need to remove the engine cover and prop. Once those are off, you can access the water passages.
There are generally 3 water passages in an outboard motor: 1) the gearcase water passage, 2) the powerhead water passage, and
3) the manifold water passage.
To clean the gearcase water passage, you’ll need to remove the lower unit. This is where things can get a little tricky, as there are a lot of parts and hoses that need to be disconnected.
Once the lower unit is off, you can access the water passage and give it a good cleaning.
The powerhead water passage is located under the cylinder head. To clean this passage, you’ll need to remove the cylinder head.
Again, there are a lot of parts and hoses that need to be disconnected, so this is not a job for the faint of heart. Once the cylinder head is off, you can access the water passage and give it a good cleaning.
The manifold water passage is located under the intake manifold.
To clean this passage, you’ll need to remove the intake manifold. This is generally the easiest of the 3 passages to clean, as there are not as many parts and hoses that need to be disconnected.
- Remove the outboard from the boat
- Drain the oil and remove the spark plugs
- Disconnect the water hose from the engine
- Remove the lower unit
- Clean the water passages with a brush and hot water
- Reassemble the engine and lower unit
- Fill the engine with oil and reconnect the spark plugs
- Reconnect the water hose to the engine
- Install the outboard on the boat
Cleaning outboard water passages
How do you clean the outboard cooling system?
Assuming you are referring to a boat engine:
Most boat engines have an open cooling system, meaning that water from the lake or ocean is used to cool the engine. As such, it is important to keep the system clean to prevent corrosion and maintain efficiency.
To clean the system, start by draining the cooling system using the petcock valve. Next, remove the thermostat and flush the engine block with fresh water. Be sure to use a soft brush to remove any debris from the engine.
Finally, flush the radiator and hoses with fresh water.
It is also a good idea to change the antifreeze and lubricate the water pump at this time. Doing so will help to prevent corrosion and maintain the life of your engine.
How do I clean my outboard thermostat housing?
If you have an outboard thermostat housing, it is important to clean it regularly to prevent rust and corrosion. Here are some tips on how to clean your outboard thermostat housing:
1. Use a soft brush to remove any dirt or debris from the housing.
2. Rinse the housing with clean water.
3. Use a mild soap to clean the housing, if necessary.
4. Rinse the housing again with clean water.
5. Allow the housing to dry completely before storing it.
Can you flush an outboard with vinegar?
There are a few ways that you can flush an outboard with vinegar. The first way is to simply pour vinegar into the outboard and then start the engine. This will cause the vinegar to circulate through the outboard and hopefully remove any build up or deposits.
The second way is to disconnect the outboard from the boat and then pour vinegar into the outboard. Again, start the engine and let the vinegar circulate. The third way is to use a vinegar-soaked rag to wipe down the outside of the outboard.
This will remove any grime or dirt that may be on the outboard.
How do you remove salt build up from an outboard motor?
Assuming you are referring to salt water and not table salt, there are a few ways to remove salt build up from an outboard motor.
One way is to use a garden hose to spray down the engine. Make sure to get in all the crevices and to remove any salt water that may have pooled.
You can also use a toothbrush or other small brush to help remove any stubborn salt build up.
Another way is to make a salt water solution using distilled water and salt. Use a ratio of 1 cup of salt per gallon of water.
Soak a clean rag in the solution and use it to scrub down the engine. Rinse the engine off with fresh water afterwards.
If the salt build up is really bad, you may need to take the engine apart and soak the parts in the salt water solution.
Be sure to rinse everything off thoroughly afterwards.
Whichever method you use, be sure to dry the engine off completely afterwards to prevent rusting.

Yamaha outboard clogged cooling system
If your Yamaha outboard engine is clogged, it’s important to take care of the problem as soon as possible. A clogged cooling system can cause your engine to overheat, which can lead to serious damage.
There are a few things you can do to clean out your cooling system.
First, you can flush the system with fresh water. This will help remove any debris that may be clogging the system. You can also use a special cooling system cleaner to help break up any stubborn clogs.
If your engine is still overheating, you may need to take it to a mechanic to have the cooling system checked out. In some cases, the problem may be more serious and require repairs.
No matter what, it’s important to keep an eye on your engine’s temperature gauge.
If you notice the engine is running hotter than usual, be sure to take action to avoid any serious damage.
Outboard cooling system clogged
If you have an outboard cooling system, you know how important it is to keep it clean and free of debris. A clogged cooling system can cause your outboard to overheat, which can lead to serious engine damage.
There are a few things you can do to prevent your cooling system from clogging up in the first place.
First, make sure that you change your outboard’s oil regularly. Old, dirty oil can cause debris to build up in the cooling system. Second, be careful when you are using your outboard.
Avoid running it in dirty or muddy water, as this can also cause debris to build up in the cooling system.
If your cooling system does become clogged, there are a few things you can do to clean it out. First, you can try using a garden hose to flush out the system.
This may not be very effective, but it’s worth a try. Second, you can remove the thermostat and flush the system with fresh water. This will remove any debris that may be stuck in the thermostat.
Finally, if all else fails, you can remove the entire cooling system and clean it out with a pressure washer.
If you take care of your outboard and keep the cooling system clean, you can avoid major engine damage. However, if your cooling system does become clogged, there are a few things you can do to clean it out and get your outboard running again.
How to remove salt build up in outboard motor
If you live in an area with high humidity, you may notice salt build-up on your outboard motor. This can happen even if you don’t use your boat in salt water. Salt build-up can cause corrosion and damage to your motor.
To remove salt build-up, you’ll need to flush your outboard motor with fresh water. You can do this by running the engine in a freshwater lake or stream. If you don’t have access to freshwater, you can use a garden hose to flush the motor with clean water.
Run the engine for a few minutes to allow the water to reach all of the salt build-up. Then, turn off the engine and let it cool. Once it’s cooled, you can remove the cowling and access the engine.
Use a brush and soap to scrub away any remaining salt build-up. Be sure to rinse the engine thoroughly with clean water. You may need to repeat this process several times to remove all of the salt build-up.
If you live in a salt-prone area, you may need to flush and clean your outboard motor more often. This will help keep your motor in good condition and prevent salt-related damage.
Conclusion
If you’ve ever taken your boat out for a day of fishing only to find that it’s not running as well as it should be, it might be time to clean out your outboard’s water passages. Over time, these passages can become clogged with salt, sand, and other debris, which can restrict water flow and cause your engine to run less efficiently.
Fortunately, cleaning out your outboard’s water passages is a relatively easy process that you can do yourself with just a few tools.
All you’ll need is a small brush, a can of compressed air, and a garden hose.
To start, remove the cowling from your outboard so that you have access to the engine. Then, use the brush to clean any debris from the water passages.
Once the passages are clear, use the compressed air to blow out any remaining debris.
Finally, reattach the cowling and start your engine. Let it run for a few minutes to make sure that the water passages are clear and that your outboard is running smoothly.
