Winterizing via the reverse flush fitting on 657X??

[Luv2Camp]

So this year was the first time winterizing a SeaDoo.... I am losing sleep thinking about if I missed something and the temps going to be freezing in my garage for sure looking at next weeks forecast...

I have a winterizing kit http://www.winterflush.com/?gclid=CMuPxd7m87oCFSbNOgodXyoA8QI I use for my boat that has a bucket with a bildge pump in it, a stand that sits in the bucket with tarp material that funnels the antifreeze from the exhaust back into the bucket. It creates a loop so I can fully ensure I have antifreeze in the engine after the thermostat opens on my boat engine...

When I winterized my 95 GTX, I used the reverse flush method by clamping off the larger diameter hose coming off of the top of the motor, hooked up the reverse flush kit to the fitting on the top of the motor and pumped the antifreeze into the reverse fitting while the engine was running.

My question is if using the flush fitting truly reverse flushes the entire system or not. Do not want to think I found a great way to winterize and find damage in the spring!

Sounds like that would work just fine. There would be plenty of pressure to get to every nook and cranny even with the cyl drain line not pinched off.

People freak out and worry about it, with good reason...I seen some bad ones, but technically they should self drain and be ok even without doing antifreeze...so doing anything should give you at least a 90% chance of being ok. Tipping the machine up and down a few times would prob put you into the 95% range.

Back in my early riding days I didnt ever winterize. 3 years in on my first SPX I had it run fine, parked in the water for a few hours and when I got back to it the engine was full of water from a base gasket that got pushed out.

I also fixed up a 720 machine that had cracked the cases b/c there was water in the little pocket between the cylinders and the back of the RV face. That isnt discussed in any manual, but after seeing that I always blow some air in that area.

RV face? What is that?

The part of the cases that the RV valve is up against.

Basically...just take your air nozzle and put it in between the cylinders and let it rip.
