Anti freeze or not??

[maa. melee]

1. Run desalting solution (with anticorrosion additives) through engine.
2. Flush engine clean.
3. Remove all plugs, caps, stopcocks, etc.
(unclog if necessary)
4. Let drain.
5. Replace all plugs, caps, stopcocks, etc.
6.Then what??????

'Air doesn't freeze, antifreeze MIGHT freeze'
I've heard this a million times. I want to keep my engine block until next season...

7. Rum and jigs.

I use straight RV antifreeze (plumbing antifreeze) It's good to minus fifty C and doesn't eat impellers or hoses.

[maa. melee]

RV juice doesn't have anticorrosion additives. :(

You got a car?...
tons of them in Boston and in places much colder and they dont freeze... treat your boat like others treat the car and your be fine...

[Peter Malcolm Jardine]

The anticorrosion additives are an issue if this is a closed cooling system that retains the antifreeze. Most of the additives are for protecting aluminum rads from the glycol. I only have antifreeze in my boat for six months at a time.

put a heater in your boat

[brad9798]

Agreed, PMJ ... that's how I do it too!

No worry at ALL about corrosion ...

Heater in boat? NO WAY. They are not reliable ... BELIEVE ME on that one.

A friend of mine recommended Salt-Away (http://www.saltawayproducts.com/) for flushing the engine prior to filling the jacket with antifreeze.

But here is a CLUE....


Water based When is the last time or even the first time that you washed out the engine block of your car with anything OTHER THAN WATER? and maybe a little baking soda?

But ifin I was selling that stuff, I'd recomend it to you for everything including brushing your teeth.

Seafarer Marine/RV Antifreeze (http://www.jamestowndistributors.com/product;part;32324;process;search;ID;,Engine.Room, Winterizing) contains corrosion inhibitors, is good to -50, etc.

So what's wrong with ethylene glycol? It works in millions of engines with nary a problem.

I've done both draining and using antifreeze, and now use automotive propelene glycol antifreeze. Reason is that it is difficult to really drain the system, and fresh water stays in low spots, the pump, etc. Mine is a raw-water cooled system, and I pump the antifreeze through the inlet until it comes out the exhaust. Propelene is less toxic then ethelene glycol, and in the spring it blows out into the water. it is similar to RV tankage antifreeze, but contains anticorosion components. An air-filled engine block also is an invitation to rust.
