I have winterized motors before, but I have never done a PWC. What do you have to do with these before winter? I have heard start them and blow the water out to put antifreeze in the engine. Just bought it this summer so never had to worry about one before.
Thanks for the help!
 
I have a 2005 Waverunner. The last two winters, I have flushed the motor with salt-away (we use it in brackish water), changed the oil, washed to engine and compartment with salt-away, drained the gas tank, removed the battery, and lubed the cables. It is fuel injected, so I put gas stabilized in the gas and ran it for a a few minutes to pull the concoction into the fuel injectors. Come spring, I added gas, recahrged the battery and it fired right up. I have a Yamaha service manual and it doesn't talk about anti-freeze.
 
What I did on my SeaDoo is hooking up water supply, put some fuel stabil in the tank, then run it while spray fogging oil into carbs and watch for smoke comes out, keep the throttle up a bit so it won't stalls, I then turn off water supply and run it for another couple of seconds to blow the water out then shut it off, remove spark plugs and spray the rest of fogging oil into cylinders and reinstall the plugs, remove the coil wire and grounded it I then bump the ignition couple times to make sure fogging oil is lube the cylinder wall then disconnect the battery, I then remove the upper cooling hose and pure "pink" anti freeze in until it comes out from the other end, reconnect the hose, wash it off and cover it up. The whole process take about 30min. or less.
 
The only thing I would add to DeeVee is that there is a grease fitting om the coupling behing the motor on the shaft that needs some grease. It also seems to help to tip the front end up as high as you can get it to blow the water out.
 
What's your manual say? My
seadoo suggests using antifreeze. Nowhere does it say to just start it up and blow the water out. Also, some are FWC and some are RWC.
 
Mine is a 1997GTX and it says nothing about antifreeze.
 
Mine did not come with a manual. I went to the website and it said something about pinching a hose and filling with antifreeze after draining engine. I was wondering if you could run antifreeze through the water hook-up?
 
Follow the information you got on the website. I fill my engine with anti-freeze as per the instruction without running the engine. The engine has already been fogged by that point.
