Antifreezeflush question/help!?!?

[shiftmx348]

Hey guys,

Im winterizing my 2016 4tec 130hp for the first time and tried to gravity feed antifreeze through the system through the hose port on the back . I started it up during the process and eventually the coolant started to shoot out the jet pump, but not the exhaust. Isnt it suppose to come out the exhaust?? What am i missing here

To ensure you get the antifreeze throughout your system, you really should use an electric pump (while the engine is running, of course). Check this video out: https://youtu.be/Grd6IwYpdo4. Good luck.

Great thanks for your help. I will get a pump and try the process. It just seemed strange to me that it would come out of the jet pump and not the exhaust as well

? , what about the newer 300's that have a flush fitting on both sides.....

For the RXP-X they recommend flushing from the port side, so that's what I'd do. Note that machines like the RXP-X with external intercoolers need a slightly different procedure to protect the intercooler from damage in freezing conditions.

Thats what im trying to figure out, the manual just shows the steps you did, mentions nothing about the other flush port nor adding antifreeze. The dealer I got it from said nothing had to be done. SMH

The antifreeze exhaust flush is not a Sea-Doo recommended procedure. My buddy Chris does it, but I don't. Draining the intercooler of all water is, however, critical if it's going to be exposed to freezing conditions. Getting the water out before long-term storage, even if it isn't going to freeze, is not a bad thing to do regardless.

But he has the 130hp so he doesn't have to worry about the intercooler bc of no supercharger right?

 

[3ftDeep]

Right. Getting excess water out of the exhaust is also important, though, but not as critical as the intercooler. One of the many reasons the 130s are considered "bullet proof".

What about the 155hp lol

 

[danowoodard]

Great YouTube channel by the way great info I know you don't put antifreeze through your sea doo the only reason I did is bc I live in upstate New York and it can get to 10 even 20 below 0 for extended periods of time do you think that's okay

 

[3ftDeep]

The 155 is also bullet proof! Actually, Chris puts antifreeze through his exhaust because it can get below freezing for days at a time. Thanks for the kind words. It helps motivate us to make more videos.

No problem keep up the good work so in your opinion is that all I should have to do ? To keep water from freezing the exhaust is the only thing cooled by sea water since engine is closed loop thanks

I'm not sure which year or model you've got, but if you've got the 155 (without an intercooler or supercharger), you probably don't need to do anything to the exhaust. I suggest you consult with your owner's manual at the following URL: http://www.operatorsguides.brp.com/...-367b3dba5f65&brands=seadoo,sportboat&type=og . If it were my machine, though, I'd probably just blow out the air like in the video if it wasn't going to go too far below zero for too long. If it was going to go to 10 to 20 degrees C below, I'd probably pump in the antifreeze. Make sure you check the engine coolant so that it won't freeze, either. Also, fill your tank (very important) and use the fuel stabilizer. Finally, I suggested you look at the manual, as each year seems to have a few different things that you need to check up on before long-term storage. Good luck.

Okay thanks for your help I appreciate it

What kind of White Rock is Chris living in?

Okay, so it doesn't go to 40 below, but it can reach -10 C for a while. Still, I had my supercharged 185 GTX under a tarp outside for 3 winters without ever blowing out the water from the exhaust and I never had a problem (until the pump dissolved on me a few miles off Salt Spring Island -that was very upsetting).
