Can a Nutra Salt system be used for freeze protection?

[Kfrasch]

My Volvo Penta 200 with an SX drive was sold with a Nutra Salt system and we boat in East Tennessee on Lake Tellico.
It would "seem" that since a Nutra Salt system injects its anti-corrosive system with a 45 second push of a button, if the tank were filled with Anti-freeze, one could extend their boating season significantly by using the Nutra Salt system for injecting Anti-freeze. Has anyone tried this and knows it to be successful?

Ayuh,.... Welcome Aboard,... Sounds like a sure fire way to end up with a cracked block,....

Yer 3.0l only has 2 drain plugs, 1 on the block, 'n 1 on the manifold, add pullin' the Big hose off the circulatin' water pump, 'n the raw water pump, then it's completely Safe to -50?....

Since I know the engineer personally that is on the VP Neutra Salt patent, I can say with athority. NO

there is no short cut for winterizing and freeze protection. drain all the water out per the instructions, clean out the drain holes with a small wire and leave dry.

Air doesnt freeze.

I have the neutra salt on my 4.3.
This is a sample of bolts i put in jam jars 12 months ago
Left bolt is the neutra salt one!
All mixed 20ml to 120ml of sea water.
I will try and find my notes on the rest of the bolts
Edit left to right, neutra salt, std glycol a/freeze, neat salt water, salt away, cant remember what i did with the last two bolts!

The first bolt was in the Neutra Salt solution?
I always liked putting antifreeze in the blocks.
Unfortunatly they outlawed that a long time ago.

Re: Can a Nutra Salt system be used for freeze protection?

the neutra salt additive needs salt water to combine with. Just like an acid needs a base to combine with to balance PH.

The original intent of the OP's question was could he add antifreeze with the neutra salt system as freeze protection. The answer is no.

as to corrosion inhibiting abilities of solutions, that is an entirely other subject.

Yep it was in the neutra salt, 20ml additive mixed with 100ml sea water, all samples mixed the same ratio
The sludge in the neutra salt solution wasnt pretty either
Both the neutra salt and the salt away solution ate away the zinc coating on the bolts over the first few days
The salt away seemed to coat the bolt in some sort of black oxide as did the neutra salt initially

Why are you testing this on a zinc coated bolt in the first place? Insides of engines aren't zinc coated and an engine block alloy will be totally different that a bolt with or without zinc.

Re: Can a Nutra Salt system be used for freeze protection?

Maybe the OP should clarify what a "Volvo Penta 200" is? If you google that, you get anything from a 20hp outboard, to a 200hp 5.0 liter, and also a mention of a 4.3 v6....???

So telling him to pull the two bolts and two hoses like a 3.0 has (which I have) might not get him winterized properly if he has a different engine.

And just for my own personal curiosity and education, you're running a salt neutralizing system on an engine run in an inland freshwater lake?
Is there some advantage to this, or was this boat originally made for saltwater?

Also, if your primary reason for this is to extend your season, maybe you should post that in the general forum, and get ideas from others that need to do so for professional reasons.....guides, etc...

Basically thats what i had to hand, ie they were free, i know engines are not zinc coated on the inside as im sure just about every other person on the planet does to.
Pretty certain the engine blocks are not alloy, i should point out that in the uk alloy means aluminium and im guessing in the usa it has a different meaning?
It was an small experiment done out of curiosity.
Not to sure i was that keen on the results though!
Still we live and learn.

Pretty sure an alloy has the same meaning world wide. Practically all metals that we use are an alloy of some type. Cast iron is steel and certain percentages of carbon and other minerals.

Alloy - Wikipedia, the free encyclopedia

Very possible neutra salt had a strong reaction to the zinc which wiped out the neutra salt in your solution.

Re: Can a Nutra Salt system be used for freeze protection?

Yes thats correct, but if you read his sentence thats not how he meant it, and if he did it was poorly worded.
Most people would say an engine block was cast iron/steel/graphited etc

Re: Can a Nutra Salt system be used for freeze protection?

Re run your test with some cast iron. Maybe with a broken off piece of a cast iron water pump. Also, you need way less neutra salt as the dilution put in the engine is a lot less than what you are doing.

I have neutra salt installed on my engine and it seems to reduce the corrosion in the manifolds.

To answer the OP's original question is that it can't be used for freeze protection
