95 gtx seizing problem[657]

[lordkull]

Hi Its me again and My seadoo had multiple problems the latest being seized up .
I wouldnt think that I did anything "wrong "that could have caused a seize I ran premix gas with oil in it at 40 t0 1 at the last and it seized I got it moving by spraying oil down the spark plug hole and tunring it back and forth.
Anyone now of any reason that a seadoo would act like its seized ?
I dont know much about them YET but Im wanting to learn.
My brother the mechanic thinks its something that hooks to the crank rabe valves or rotax or something I had another premix gas post but I cannot find it
any suggestions ?

water intrusion or other liquid on cylinder top as the piston entered the squish may
have broken the land or piston ring.

Or...


Bad crank seals. An air leak in the bottom half will roast an engine quick.

Thank you for the replies fellasI have taken the head off and there is no water whatsoever in the cylinders.
Is there anyway to check the crankseals without pulling the motor?

I am going to pull my pump and ck it again .
its weird as its not seized any longer [after i squirted oil down and moved it by hand ] but its still a bit stiff and hard to turn by hand.
it blows my mind as all the 2strokes from my past were either good or bad this is inbetween

thanks Mark

also the front plug was brownish and more well burnt than the back which was "normal"
