When I got my ski I told my sales person I was going to take it out on every now and then to local beaches they told me I would be fine just to flush the exhaust with this grey adapter they gave me since it's a closed cooling system but I keep seeing threads of people here buying the flush kit so what's correct? Lol

They may have already installed the flush kit. I had the same experience with mine, they had pre installed it and just gave me the grey adapter. If it isnt already installed the flush kit is what enables you to attach a garden hose to the unit.

I made a little adapter for about 3 dollars. 12" of 1/2 ID silicone tubing, a male 5/8" garden hose fitting shoved in the end. And an on off valve for the end of the garden hose. Screw in hose, push on flush fitting, turn off valve, turn on hose. Start ski, turn on valve. Turn off valve, stop ski. disconnect. I'll get some pictures up when I get a chance. Fits right underneath the seat so it's always with my ski.

Do you have IBR? Seems the IBR might get in the way for us IBR owners.

Go to Home Depot and pick up one of these things:

http://www.homedepot.com/p/Orbit-1-2-in-x-24-in-Riser-Flex-Pipe-37151/100154591

Cut it in half, push it onto the flush point on the ski. Even if you have iBR, the stiffness of the pipe will allow you to push it on without removing the bucket. Then push the cut end of a garden hose onto it. For only a dollar you now have a flush system on your Spark.

If you want to get fancy, you can get fittings to install a quick-disconnect system onto that.

This is actually a really good suggestion, is this one you came up with or seen elsewhere?

I came up with it myself. I like to tinker, and often find creative solutions to mechanical problems. I'm just surprised that no one else had figured this out yet.

Slightly confused by this.....my dealer told me to stick a normal garden hose on the nipple at the back........can anyone advise if this is the right way of doing it?

Do I need to flush spark if I only ride in fresh water?

Thanks in advance
I only ride in Fresh water and never flushed my 2002, 2003, and 2008 RXT-X (All 4 techs) and similar as the engine is anti freeze cooled and the exhaust is water cooled!

I made a flush kit But the only time I,m going to flush it is at the end of the season as part of winterizing the Spark. If you don,t ski in salt water all flushing does is heat up the drive train because its Not in water?

You only flush for about 30 sec...different then like a yamaha where its a few min to flush entire engine

I have I BR and was able to get a hose clamp on without removing Ibr.found a hose clamp with a plastic knob . Shoved the 1/2 pipe on and turned the knob with one finger. Not easy to do but it beats removing the ibr.
