    New Boy would like info

    Hi,

    Although I've had ski's for over 25 years I have just purchased a 255hp speedster that I don't really know too much about.

    I presume that although it's a closed loop system I will need to winterise in some way, I bet this has been asked before so sorry to raise it again.


    If anyone can answer before the cold sets in later this week that would be great, also where can I get hold of preferably a free manual user & service.


    Cheers
    Dec


    Oh by the way I can't imagine the cooling system is much different to either the 185, 215 or 255 RXP?

    I agree but not having owned a supercharged Seadoo before i don't really know about winterising.

    I have however obtained an owners manual that explains how to add antifreeze to the exhaust manifold and intercooler.

    One problem I do have though is how to change the antifreeze in the closed loop cooling system, the manual refers to dealer task only.

    I would like to change it mainly because I suspect it has not been changed since build (I've only just purchased it) but also this boat has just arrived from Spain. I have checked the level of cold protection with an hydrometer and it reads only -5 degrees.

    Which hose would be best to remove to drain the system?

    I have also noticed a black plastic plug on the top left of the jet pump, is this a system drain?

    Please help before the freezing get any worse here in the UK.
