    Overheating Gremlin

    Hi everyone,

    I started this thread (http://www.greenhulk.net/forums/showthread.php?t=224696) over in the "Sea Doo Open Discussion" forum.

    Just making reference to it here as I wasn't sure which section was the best.

    Thanks in advance.

    Are the holes in the Midpipe clogged? They inject water into the waterbox, which is where 1 of the 2 sensors is located...

    Hi skidoochris,

    Appreciate the reply and suggestion but ski's engine is not actually overheating. Issue appears to be an electrical/electronic gremlin somewhere.

    Thanks.

    Hi Danny,

    I will ask ski's mechanic to confirm whether or not this has been checked.

    Regards.

    You said in the other post the alarm sounds when it gets to 110 degs. That is when the alarm is supposed to sound. It is overheating.

    Hi k-dub,

    Mechanic has confirmed engine is not actually overheating. Issue seems to be an electrical/electronic gremlin somewhere.

    Thanks for your reply.

    Hi joe w,

    Water box and its sensor have been replaced. No leaks visible with cooling system (fresh water or coolant). Hose clamps are all tight.

    Thanks.

    Hi everyone,

    Finally worked out what was responsible for this issue, the CLCS ride-plate. The coolant circulating through it was flowing well, a little too well (ie. quickly/freely). One of the internal channel walls/seals had broken/split which created a shortcut for the coolant, allowing it to flow through the plate too fast, not allowing it to cool down enough, causing the engine to overheat. Below is a diagram of a CLCS ride-plate with its top removed.

    After my ski's ride-plate was replaced I took it for a water test. Rode ski for about 20 minutes at full speed (WOT) and the engine temp displayed on the dash remained between 89-90 degrees - perfect !

    So, if your engine ever overheats remember this thread (and the other one I created). The fact that your ride-plate might be flowing freely is not enough, the coolant has to remain inside these plates for a certain length of time for it cool down properly.

    Thanks for your replies - all the best.
