All,

I just recently bought a 2001 GP800R and a 2002 FX 140.

How often should I flush the engine? I know this is typically to wash dirt out of the engine that may have been sucked in or other unwanted particles, but what is a good frequency?

Also, what is the appropriate sequence, for instance I believe it is this:

1.) Attach water hose with nozzle adapter.
2.) Turn water on.
3.) start jet ski.
4.) turn off water after about 30 seconds.
5.)cut engine off around 5 seconds after that.

Is this the right sequence and am I missing anything in between? I know I can ruin an engine if I do not do it correctly so I'd like to be 100% sure.

Thanks!

NO! NO! NO!
Correct sequence:
1. Attach hose to ski (water off)
2. Start engine first!!!
3. Now start water
4 Turn off water
5. Turn off engine

The engine can run for 20 seconds or so with no water. ALWAYS START THE ENGINE FIRST OR YOU RISK PUMPING WATER THROUGH AN OPEN EXHAUST VALVE AND THEN BAD THINGS HAPPEN!

If you ride in fresh water that is fairly clean, you really don't need to flush until the end of the season when you are gettng ready to store the ski. If your lake/river has lots of trash, etc., you may want to flush more often, maybe once every 5th ride, etc..

If you ride in salt water, you should do a fresh water flush after every ride.
