How do you de-water a Jet Ski engine?

Answer 1

here is what i wrote for Yamaha ski for a guy.

it is for a 2003 Yamaha xl700.. but its the same thing for all Yamaha skis.

Please, write what type of ski you have first off.. its different for each ski brand.

To flush a ski out, you need a special piece that connects to the injector port.

This piece also connects to your normal garden hose.

1. Connect the garden hose to your part, then your part to your injector port on the inside of your engine
2. Turn on your Yamaha, and let it idle for about 2-3 seconds.
3. Then turn on the water hose, and rev it up a few times. Do not rev it up to high. Do this for about 20-30 seconds and then turn your hose off first.
4. let your ski idle and rev it up a few more times, to get excess water out. and then your done!

   **Remember to turn the water off first and then your ski. if you turn your ski off first, and then the water it can backfill and cause you many problems and money.

Also unplug your drain plugs and let any of that water out. This really should be done at the lake so that while pulling up the ramp at the angle, more water will hopefully come out.

Also while flushing your system. This is a good time to get your 3m or whatever marine wax or product you use to clean your ski.

HERE IS THE LINK FOR THE INJECTOR PIECE! ITS A CHEAP PART THAT COST LESS THAN $2.50.

riva you can find all of the OEM Parts ( stock parts ) for any ski, any year.

copy and paste the link. IT IS PART #60~scroll down to part #60 and buy. Pretty straight forward. Any other ski help, I will be able to help!
