John you'll find I clown around a fair bit oin these forums
BUT if something interests me I change gears into Serious Mode, I'm not one who just lunges out & says the 1st thing which comes into my head & you would've noticed by my previous reply here I put some thought into it & most importanately I gave reasons why I thought this product to be not what it was cranked up to be.
Esp the way it was portrayed in the pics I call that false advertising & very misleading.
My trade background was done on Alloys Tech course was pretty crappy like most Tech Colledge courses go but I did my time @ QANTAS & spend another near 12 months in their own colledge B4 being released out into the hangers that was every working day of the week & most of that was theory study.
I've 4gotten most of what was taught but still know the fundamental basics of alloys, yes salt can harm your alloy outboards but just as bad can be this product called Salt-Away
If it is using a acid to do it's cleaning have a read of the bottle & see what the ingredients are ??????????????????
Not that long ago I rebuilt my bigger boat not one for doing things 1/2 cocked I pulled my 11 yo 2 stroke yammy's apart whilst I was @ it.
Powerheads off motors striped virtually right down & after 11 years / 500 odd hrs the insides were pretty spotless just a wee bit of corrosion on the water/exhaust plates which were replaced.
I did nothing special in all those years exept what Rumpus said, when I did flush it was prolonged flushing none of this bullcrap some peeps do 10 seconds & she'll be right mate.
Dont know if some of you guys recall going backabout 20 odd year now ??
A stink came about in regards to coolants in motor cars, well they found certain coolants corroded away alloy head engines cause if I recall correctly a light acid was in the solution.
