Location for the connector to flush and winterized my 2005 Seadoo Sportster 4 Tec 215 SCIC

[Luc’s Sportster SCIC]

Hi, I’m trying to locate the connector to flush (to connect the garden hose) and to winterized my Sportster. I’ve looked at other discussion they’ve mention top left at the back. But when I looked I don’t see any type of connection. Does anyone knows where I should look (picture if possible) to connect the garden hose?
thanks,

Hi xspook, I’ve looked and I don’t see that connection showed in page 51. There’s nothing. Attached are pictures of what I can see. 1st picture from right and the 2nd is from the left.

Interesting...I don't have a SeaDoo boat, so can't offer much more help other than post your question over on GreenHulk. They have a subforum just for Seadoo boats:

It is the open threaded hole in the first photo below the bolt.

A standard male threaded hose end will screw into that.

I added the quick attach one from Seadoo with the hose.

MacSeaDoo,

Thank you and now my second question is my engine is not not running (Supercharger issue) can I add antifreeze by gravity to make sure I cover all the corners for the Winter?

I have not tried to do this without running. I learned just running is not enough to make sure you have completely flushed the antifreeze through the heat exchanger for the supercharger located in the intake manifold. Aproximately 4 of the copper tubes on the bottom of the heat exhanger were 2 times the diameter of the others- water froze in them.

This year after running the antifreeze I am going to disconnect hoses and use air pressure to blow out all residual water in the heat exchanger and the exhaust manifold.

We have a 2005 RXT 215 SC Engine

 

[Luc’s Sportster SCIC]

I’ve removed the exhaust manifold to give more room to remove the supercharged and removed the water from it. I was thinking if I make a look with the two rubber hoses from the manifold and then run ant freeze by gravity it might work…..

Seems like every spring someone with a 215 tells me they blew it out the system with compressed air to winterize and now it isn't running right. First thing I change is the intercooler that split from water collecting in the bottom of it. You have to use antifreeze in the intercooler, air doesn't work. You can use a pressurized hose to force it through the system or pour directly into the ic, gravity alone through the flush port won't work unless you're on a 5 story building pouring it in the hose.

 

[dcm0123]

How do you get the antifreeze into the inter-cooler?
I was thinking to use a drill operated pump to force it through the hose inlet above the jet pump or possibly disconnect the hoses from the inter-cooler and pump directly into it.

Looking at the diagram below with all the inter-connecting Tees I question if using the hose inlet will work.

Do you run un-diluted engine antifreeze through it or RV drain system antifreeze?

 

[Poormanracing]

Blow air thru water inlet and it will blow the water out of intercooler.find intercooler and there should be a 1/4 inch hose coming of the top passenger side of intercooler that is the tell tail find where that goes out side of boat and blow no more than 55 psi thru that.im just getting ready to do a chapparal jet boat and see where that bleeds off and tell you where it IS.

 

[Poormanracing]

Your intercooler is has a tee fitting coming of the exhaust and on the back has two 3/4 inch hoses can take those off and put antifreeze thru there.but air should be just fine as it is mostly self draining

 

[ski-d00]

The 215s are not self draining and they do not have a vent. The newer ICs have vents and are self draining, 215s definitely not, and blowing air through it and not using any antifreeze is the best way to ruin it when winterizing.

 

[dcm0123]

Appreciate the response from everyone.
I am going to use a drill operated pump to circulate the antifreeze through the entire system using the garden hose connection first then remove the IC hoses and run it directly through the IC.
The back end of the IC is lower than the front which has the hoses so I understand why water will not drain from it on its own. I did not realize this until after I had the problem.

 

[Poormanracing]

Got boats crossed didn't read the heading but didn't sea Doo come up with an updated procedure for doing the old intercooler machines in the flame arrestor.because of epa and antifreeze and only recommend 55 psi of air

 

[Luc’s Sportster SCIC]

Hi guy’s, I can see an option by attaching the hoses (see picture) with a T and a piece of hose to be able to run the antifreez by gravity. Does it make sense? I’ve seen a guy on Youtube doing it by gravity. The exhaust has been removed and emptied of water. I me be ok to use the drill operated pump to circulate the antifreeze.

 

[dcm0123]

This will not circulate water through the intercooler which is in front of the engine (two hoses going to left side of picture).
Appreciate your suggestion.

 

[Luc’s Sportster SCIC]

Can I just remove the two hoses and shoot some air in it?

 

[Luc’s Sportster SCIC]

To understand better, the fresh water goes into the IC before it goes anywhere else? I guess there’s a coil inside the IC that circular in and out?

 

[dcm0123]

Some folks say air alone will work, others say it will not.

Step 1- I will use a pump to force RV Antifreeze through the system using the garden hose flush connector. Using a funnel as I did in the past did not work because as someone said you would have to hold the funnel up very high to get it to flow through the IC.

Step 2 - I will remove the hoses from the IC and pump RV antifreeze through it then use air to blow it out. If I find the IC full of antifreeze when I pull the hoses off, maybe next year I will skip this step.

Not worth the risk of having it freeze again.

 

[Luc’s Sportster SCIC]

Hi, I thing I got it this time. I pulled the hose from the hull at the back that goes to the return of the IC. I raised it up and pour anti freeze until it can out of the connector for flushing at the back. by doing so, the anti freeze went throughout the IC and back into the manifold etc.. it’s garantie to have all the water out. Mind you my motor is not running so I think I got it. Am I right?

 

[dcm0123]

Used low cost submersible Flotec pump to push the antifreeze through the system using the garden hose connection above the jet pump with motor running. Took less than a minute to emty the pail of 3 gallons. The pump has a fitting for the garden hose built into it which I connected a 6 foot hose to.
Then I removed the inter-cooler hoses and pumped 1 gallon directly through it.
Then used air to blow the inter-cooler clear.

I believe this is the best way to winterize when the inter-cooler is mounted in the intake since gravity alone will not empty it.. Not sure what is the proper way for the external coolers used in later models.

Hi, in normal circumstances it would work. But, the problem I have is that my engine doesn’t run. Supercharged issue and the dealers are booked solid. I think this is the only way I can go…

If I was you I would power flush the heat exchanger with antifreeze by connecting the hose directly to it as I did and use a pump to push it through in high volume.

I was using a funnel to do this through the flush port above the jet pump last year and it did not displace all of the water in the heat exchanger which is why it froze last winter.

If you have an intake mounted heat exchanger like mine (2005), the end furthest into the intake is tilted down. It will not drain all the water on its own. You need to make sure the water is displaced by the antifreeze.

If you cannot do this, I would at least disconnect both pipes on it and use air to blow any remaining water out.
