2012 rxt - left water run during flushing after engine stoped.

[Steve2012]

When I was flushing the engine, I accidentally stopped the engine before turning off the water hose. I quickly shut off the hose after about 5-7 seconds. My concern is that the manual states that if you shut off the engine before the hose, water can get into the engine, but it doesn't say what to do if this happens. Based on the short time the hose was running, is this a major concern? Does it need to be serviced, or do I just run it as normal and watch for any problems?

Thanks

Steve, welcome to the forum.
One way to check is to remove the spark plugs and crank the motor over.....does water come out? If no, then you are good to go. No worries.

If yes, then keep cranking (5 seconds at a time then stop for cool down of 30 seconds) until all water is out. Then start engine and run it on the lake for 15-20 minutes some what hard to finish drying things out

Thanks, I'll give that a try in the morning.

Actually I would do it now. the longer water (if any) sits the faster rust will form.....doesn't take long on cylinder walls.

Yes, it is a 260 4 -tek with close loop cooling, but page 136 of my owners manual states "warning, always close the tap before stopping the engine. If not, water will get into the engine" This is what has me spooked. I did start it/flush it again immediately after the mistake ( which probably made it worse if water did get in the engine).

If I pull the plugs this morning and water is present, is it easy to tell the water apart from the gas?

You have a 4-tek, the information does NOT apply to your ski. Your ski has a closed loop cooling system leaving the hose on won't effect your engine. You'll be wasting your time doing the above.

It does apply. The 4-tec has two cooling systems. One is a closed loop system that cools the engine. The other is an open loop system that uses fresh water to cool the exhaust manifold and the intercooler. This water also enters the exhaust stream (like a 2-stroke) and will fill the engine if it's not running. Same rules apply. It's the same reason you have to pinch off one of the cooling lines when towing a 4-tec.

If you only ran it for 5 - 7 seconds, then it's highly unlikely that any water got into the engine. Besides, if you ran it after again, I'm sure you're good to go. Check the plugs regardless.

Towed mine yeterday-- pulled the plugs just to be sure, no water

Lou, I wouldn't think of giving advice to anybody in the 2-Stroke forum as I don't have a 2-stroke engine watercraft and have no experience with them... you're here in the 4TEC forum giving Steve completely incorrect 4TEC advice that could damage his engine Lou. Apparently you don't even own a watercraft with the 4TEC engine so how can you say what does or does not apply to the 4TEC's? Come'on man!

Chester has the right of it Steve, if it'd had water in the cylinders it would not have started the piston's would have been hydrolocked. It takes more than 6 seconds for enough water to flow into the exhaust manifold to overflow into the head and down into a cylinder, but there's no exact safe amount of time which is why the procedure is ALWAYS: Engine-On, Water-On then Water-Off, Engine-Off.

Do check your engine dipstick however and if the oil on the stick looks at all milky then do an oil and filter change immediately, ok? It's highly unlikely even a drop of water made it into the engine however, but an ounce of prevention yields a pound or more of cure (and a little peace of mind, too!).

I apologize for posting in this section, I am retracting my comments and promise never to darken the doorsteps of the 4-tek section again.

Thanks again for the advice, I pulled the plugs which only took a few minutes and thankfully I didn't see any signs of water (I also had looked at the dipstick as well). I cranked it over 5 or six times and only a fine mist of fuel came up. I put it back together and ran it for 2.5 hours today. It ran great all day and I got it up to 70mph on a few passes around the lake.

I knew the proper flushing proceedure, but just just one of those mental errors. Luckily I caught it in time.
