Flushing of Outboards

[Splash]

I have read that you can flush your outboard through the flush port to help keep the sediment and sand from building up in the cooling passages.

I also read that you can purchase a quick connect/disconnect adaptor system for the port that makes flushing super convenient, literally a "snap".

Anyone use this adaptor system and if so, source to acquire them from?

Hey splash

Seriously, I believe that it is not something that I would count on to flush the outboard efficiently. As it is only cold water going through it, but when you put the flushing muffs on you have the motor running. And will get the heat into it, to help to get the salt out.

I do have the same fitting on my Yammie, it is good for when you get home late so you don't make to much noise.

splash if the engine has a flushing adaptor on the motor then use it happily as I reckon that the engine makers know what they are doing . I use mine and the silent flushing is great I do it with a tap timer for 45 mins when I get home from fishing at 1 or 2 in the morning

I asked this question of the Suzuki rep when we bought our DF175, he replied that it is OK to use the flush port, but you will get better results using muffs as the water is hot and dissolves the salt better. I choose not to pull apart an engine that is working fine to do comparative tests, but I can see his logic. Unless you have neighbor issues with noise, I would use muffs.

Agree with Thy, I don't use the flush port any more having read a few threads and comments on the topic. You want the water going up through the water pump which you don't get with the flush port. Flush ports were developed for motors that live on the water or at serviced marinas where the support staff can flush the motor without being given the keys.

interesting points - thank you.

anyone show me a link referring to this flushing port?

Hey Guys,

The other thing to remember is the heat in the water will open the thermostat as well. As salt will build up behind it I had it happen to me, when I had a service done there was corrosion behind it and that is on a 2008 model outboard.

flsuh port is could for those late night returns, but i always give the motor a run on the muffs the following morning. Same reason you wash your reels in warm water, dissolves the salt better. Also, in mine, the flush port pushes water through the system the opposite way the impeller does, so i figure good to do both as it leaves a very little chance anything will get stuck

Have a look on here should give you a bit of help,

I have never done this, running the motor while using the the flushing port.

Flush the water passages as follows
-shift the motor into Neutral and remove the propeller
-remove the flush plug and install the flushing attachment. Plug the water intake holes with a piece of duct tape.
-connect a garden hose to the flushing attachment and turn on the water to obtain a good water flow.
-start the motor and let it idle for about five minutes. This will clean the salt water out of the cooling system.
-shut the engine off and then turn off the water. Be sure to shut the engine off first.
-reinstall the flush plug and remove the duct tape from the water intake hole.

BUT PLEASE REFER TO YOU OWNER MANUAL AS TO WHAT YOU CAN DO OR GO TO THE DEALER.

What else you should do is undo the flush adaptor whilst flushing with the muffs. Because you can flush for five minutes with the muffs then undo the adaptor ( with yamys) and the hole line is still full of salt wate,r and sand if you have been in shallow water . Try it you would be surprised just undo the atttachment for a few seconds and it will flush out the salt and sand.

Any comments about washing your motor in a drum.

Motor running, water hot, do that whilst washing all the other parts
and filleting a big tub of fish??

Have fun Haji-Baba

[Gon Fishun]

Yep , always run the motor in a drum if possble, quiet, clean and doesnt annoy anybody. A chap I met not so long ago has a 200hp merc, which did destroyed itself due to a mechanic ?? . When he traded it for another motor the dealer said the old water galleries were as clean a whistle. How did he do it? 1 litre of dish washing liquid in a drum that he always flushed his motor in. I have no reason to disbelieve him.

[oldboot]

Personaly I have never used muffs, I always flush in a drum.

Definitely much quieter and less messy....

And I agree that unless you are getting the water warm enough to open the thermostat......you are not doing a proper job.

I will quite happily run my motor for 20 minutes to half an hour, in the tub......it can barely be heard inside the house.

Not sure that I like the idea of leaving deterget residue in the motor though.....I would quite happily give the motor a long detergent fush before taking it out for a run though......it would shift any built up carp.

G'day,

My Suzuki owners manual (DF175) says that muffs should be used wherever possible. It says that the two ports (one in the back of the engine cover and the other in the top of the leg) can be used in places where the engine can't be started or where water pressure or quality is low. This might include camping grounds and places where exhaust and noise pollution is unacceptable or tank feed is too low pressure.

Boat dealers sell flushing tanks that collapse for easy transport. These allow you to muffle the sound of the exhaust a bit but the exhaust gases will still come out of the water. They are also not water efficient.
