how long should you flush engine?? after salt water

[BobH]

Took the 185 Inboard SeaRay over to Clearwater today for a nice day on the open sea, (but not to far ). Anyway what is the normal flush time for the engine with fresh water? Thanks BobH

If the engine is warm I normally flush for about 5 min. That's assuming your thermostats are open or will open quickly because the temp is still up. If doing it cold, keep an eye on your temp gauge and flush for about 5 min after you get up to temp. That way you know it's getting through the block and entire cooling system.

I flush my 185/4.3L for 10-15 mins AFTER the engine is up to operating temp.

After getting engines up to temps, I will taste samples of the water until there's no more salt.
Lots of times I get back to the marina after the forklift guys are gone, but I have a deal with one guy who will flush my engines every time the boat comes out of the water, and he uses the same "technique".

I use this Salt-Away product about ounce a month or so - not sure how great it really is but makes me feel better running through engine after being in salt water.

I used the taste method on my OB as well. As long as your to temp and the it's flowing through the block I would let it for for a few minutes and then taste the water coming out. Once the salt was gone I wa done. Or you could go by the 2 beer method which works well too! :grin:

I use the Salt Eliminator (same kinda stuff as Salt Away) auto dispenser. When that runs out (dispenser goes from blue color of the chemical to clear water) then I shut it down. Probably 10 minutes or so. Engine temp is always at t-stat temp when I start as its just a short tow from the ramp to my house.

I generally pull out, move forward about 40' in my back yard, hook up flush, turn on water, get in boat, start engine, it runs while I get everything out that I can, usually 15 to 20 min, then put SaltAway dispenser in line and run until water is foaming good coming out of engine, shut down. Turn off water, remove flush, use balance of SaltAway to rinse salt off of boat and trailer.

I use SaltAway also always bring engine up to operating temp then run saltaway thru till foam comes out then shut it down you want the chemical to stay inside the manifolds and engine. You need to run it up to operating temp because of the pourous metals of the manifolds and block will hold salt particles if they are not up to operating temp when not using saltaway I run it for about 5 mins after it's up to temp. This is the way our marina always does it before dry rack storage if I forget to leave the saltaway out.

Warm engines, salt away for 5 mins , shut down for 10 mins, rinse until no more foam. Done
I also do the mercury 6hp

I'm curious why you rinse after using saltaway? The reason I ask is that I thought saltaway leaves a protective coating over the parts it touches in addition to removing existing salt, therefore, I don't try to rinse it away after running it though my engine.

Yo Eng !!!! I was a Plumber at McGuire from 1982 thru 1999. The C-141 until 1993 then the KC-10. The 141 was a workhorse until the powers to be decided that they wanted a new toy.

OK, I'm not an "old Salt" just a skeptical relatively new boater. While I did have the dealer install a fresh water system on my 2012 260 Sundecker, and I use it religiously, I always have wondered what good any of the flush or Saltaway or Salteliminator or any of those products do. My view is that the manifolds are cast iron which rusts fairly quickly whether it is fresh water or salt water. MAYBE, we can get a year or two additional before we need to replace them or not. My logic (probably flawed) was that a prospective buyer of my boat would be more likely to believe I flushed regularly with fresh water cause I spent the money to add the aftermarket flush kit than if I claimed I always used some 3rd party product which is not scientifically proven. Don't know what is right or wrong, just know that if a boat/car/any mechanical device can be proven to be well cared for, you will probably get a better price when you sell.
Make sense to anyone? Just my unsubstantiated opinion.

Don't know the true benefits of the salt away other than it will dissolve salt that may have been sitting for a day or two if you don't flush right away, flushing with just water won't do the trick. it also contIns a rust inhibitor , water does not .As far as a mechanical device , I installed these so whether I flush with water or another product the next buyer will know I did mine religiously also
