Outboard Flushing
Morning all...I've searched on here and come to the conclusion the way I'm flushing is right . That is ear muffs until engine is warm and the telltale is peeing tapwater Suzi 140...however a mate swears by just using the top inlet and not running the engine yammy 150 . The concern , I put forward is that the bottom leg and pump aren't being flushed of salt . His thoughts were that's why the inlet is on there for and you don't need to flush via muffs ...a interesting point that was brought up was that the muffs depending on the seal would take a minute or so to prime up fully and that could cause premature wear and tear as well...personally I think I'll keep doing , what I'm doing ...however it begs the question , if it is better via the muffs while would they have the inlet there if it was a inferior clean ???

noiseles flush
you are both right.
you can flush with the muffs and motor running, or through the connection without the motor running (noiseless flush).
both equally effective.

they are not equally effective
the only way to get a complete flush of the whole cooling system is via muffs they make the other connection mainly for the us freshwater lake fisherman market unfortunatly here in wa we just dont have freshwater lakes of any decent size to go boating on so 99.9% of our motors are run in salt water so if you love your motor you would want to flush it properly right ? just speak to any mechanic or dealer they will tell you the same thing

That's what the dealer told me
Perhaps the excuse they use for mercurys being so shit.
a certain Suzuki dealer (all they sell is boats..), told me the noiseless flush is equally effective.

use the muffs
i was told by my mechanic when i had my yammy that the only proper way to completely flush your motor was through the muffs!
ALL FISHERMEN ARE LIARS EXCEPT YOU AND ME! AND IM NOT SO SURE ABOUT YOU!

i had a yamaha 60HP four stroke and allways flushed with muffs.i would be a bit worried if it was taking a minute to prime though
i used to turn the hose on and by the time i startd the motor it was pumping water everywhere.the telltale should dribble water
even when cold.i used to run mine untill the telltale water was warm and then a few minutes more.
cheers

I just use the top flushing
I just use the top flushing port. I do it at the ramp, when the engine is still hot. After about 20 seconds, there is an obvious change in pressure at the tell tale. I assume this is when the thermostat closes. I reckon I am flushing the motor adequately.

Also, is sea water left in the engine doing less harm than Karratha water (crunchy calcium water)

Agree pale ale. Motors are
Agree pale ale. Motors are designed for salt water. I've tried heaps of different ways but last thing you want is calcium build up. Hedland water is just as bad as Karratha.
Use the boat heaps is the main thing. Leave it in the drive way then the dramas will start.

Suppose it's each to their own , particularly with the boys up north salt vs calcium ...I thought the salt would solidify fairly quickly once dry and stick like shit to a blanket thereafter and future waterflow would just pass over it and end up clogging and being detrimental as is it's nature...same as everything else hull , trailer , rods and reels wash the salt off asap

Salt disolves very easy with fresh water. Problem I have is I do heaps of overnighters,trailer sits at the ramps for days with no washdown. Wish we had a nice fishing club with washdown facilities. would be great to wash down trailer after launching on overnights.

If you saw the state of a kettle after a few months or the inside of a hot water system in Hedland you would see why you dont want that water anywhere inside your outboard. CCC is on the money. Regular use is the key.

Probably worth getting a rainwater tank at your house dedicated purely to boat cleaning up there by the sounds of it.

Pilbara rain water
then youd be opening up the debate, of whether salt, calcium or iron ore dust is more detrimental!

Good idea but that would require guttering. Not something you see in cyclone prone areas but its got me thinking.

The manual for my Yamaha
The manual for my Yamaha Saltwater Series II (175HP) says to use the flush port which I do most of the time. The odd occasion I will use the muffs.

60HP 4 stroke Yammy top port
60HP 4 stroke Yammy top port only, had no problems in 5 years.
My local ramp is in a river so the water wouldn't be as salty, not sure if this helps?

Muffs or even better leg in Drum, as noiseless does not flush bottom leg or through the thermostat.

I thought it bypasses the thermostat?
Regardless though, thermostats have a small hole in them to allow a small amount of flow though anyway.
