Default Salt Away, A New Engine, Raw Water Cooled

I just replaced a diesel engine in a friends 30' sailboat. (what a b***h)

I was going to rebuild it but, the old engine was totally destroyed inside, I retrofitted a Kubota to it and in the interest of keeping this thing alive in salt, for more than 5 years, I am wondering if this salt away stuff is worth the hassle/money?

Plus, I might use it on my Yam150 when I flush...

Thanks Guys.

I use it in my outboard and my Suzuki. I can say that when I it is a rough day and I take spray on the boat, I use salt away to rinse the hull....salt is gone. I believe it works.

I used Rydlyme to flush out my raw water system a few years ago, and after I recirculated it through the engines 2 hours the gear oil cooler looked brand new. The marina tech was doing a generator with a overheat problem. I told him what I had done and he tried it on the generator. Cleaned it right out.

I started using it on my outboards after I saw the thermostats at the 100-hour service. Not too much of a hassle once you rig up your flush hose with the salt away thing inline. I'll let you know if it works when I see them at the 200-hour.

I just posted these pics in another thread. This is one of my motors/thermostat at 120 hrs using salt away almost every time I use the boat.

Why salt water cooled diesel? find a used fresh water cooling system and fit it in. You're just gonna ruin another engine.

Bill, I have never seen a purely salt water cooled diesel. Salt water is used to cool the engine fresh water through the heat exchanger, the transmission oil through a gear oil cooler and the hot air from the turbo charger through the after cooler. These things get salted up and that reduces their efficiency. These salt removal products do a great job removing salt buildup.

I haven't either, but it IS a sailboat and may have some weird raw water cooling system on a non-marinized engine, according to the OP.

I really don't understand either. Salt is the product of an acid and a base, and it dissolves, but doesn't chemically break down.

snake oil, flush it with water for 15 minutes and it will be fine.

That's just BS. SaltAway is a great product that works as advertised.

Seems somewhat counter productive to cool a supposedly long life diesel engine with salt water.

Used both salt away and CRC equivalent, both worked well. Flushed engines few minutes, then with fresh water.

Huh? It removes salt deposits and salt residue like a champ, but I'm sure the chemistry of it's contents is a trade secret.
