Flush out fitting

[ALR1955]

Should there be a plug in the "flush out" fitting in the bac of my Sportster 215 4TEC SCIC or should it be open?? My vote is to plug it??

Thanks

There should not be a plug in the hose fitting on the back of the flush out fitting.

Thanks for the info. I almost went ahead and plugged it

Quick disconnect

It is all right to leave the quick disconnect screwed into that flush connection. I was told by the dealer tech that is was OK but this thread sounds like a good place to double check.

You caoul leave teh threaded nipple part on the flushing end of the pipe. I leave the quick connect end on the garden hose. That way the water pressure wont go into the engine till you connect it. I also added a cut off valve on the hose so I can turn it on and shut it off when I'm done flushing for 15 sec. on the hose...shut off the engine, then disconnect the water connection.

I didn't get the quick disconnect fitting for the hose when I got the boat. I had figured on just sipping the hose on the fitting, it about 6 inches long and after the motor is started , turning on the water for the flush. When finished flushing shut off the water and let it run about 10 seconds. Is there anything wrong with this method or should I try to find a quick disconnect fitting for the hose?

I use the same set up as Karl. It's not that doing it any other way is wrong. Using a quick disconnect and in-line valve just makes the job a lot easier, and the parts needed are pretty cheap, 10 bucks max. if you get really good stuff.

i never liked the idea of a quick connect left onto the boat
most i have seen have a smaller inside diameter
i would think that it would reduce water flow when the boat was running
since this is the cooling water exit when the boat is running in the water i would think it would reduce the overall cooling flow
what ya guys think? am i too concerned?

mud has a good point the quick connect that I have hooked up on both of mine does create a smaller diameter.. I have always used the cheap ones you get at home depot for 1.50, and then just pop the hose on whenever I need to... Should I be taking out the male end when im done with a flush, will leaving it in cause any progressive long term damage to my ski's ?

Volume....

Volume verses pressure?

Most skis are designed to attach and leave the quick flush connection attached. Of course, you must use the end of the quick connect that allows free flow and not the locking part. I actually had a friend bring his ski in because it was overheating. I saw he had gotten a double nipple and attached the snap that was the locking part, no water flow at all.

I don't think, leaving the flush connector fitting in the water outlet has a great enough restriction to cause any ill affects on cooling. Seems I read in one of our shop manuals, to leave it in for ease of flushing.

The outlet diameter of our flush port is about 3/4". The flush fitting is about 1/2". Mine, along with a few of my friends, leave them in as a permanent fitting for ease of flushing. I've never known one to cause any problems with cooling.

If you already have some type pre-existing problem to cooling flow, then it could add to it and magnify your problem. But, alone.... No, I don't think there would be any problems to affect your cooling circuit......:cheers:

i also agree do not plug up that fitting.. it helps the engine drain by providing another port for the air to bleed in when out of the water. if you ever have to be towed it keeps the water from backing up and going into the intake.
