Ok. So my buddy gave me a 1995 seadoo hx that was sitting outside for three years. I have fixed about 3 different things that were wrong with it. I had to buy a knew starter because it was so rusted it would not move but now their is a bigger problem. The motor is siezed and i dont know what to do. I have taken the motor out of the hull and taken the head cap off of the head to take a look at the pistons. So much rust was in there i couldnt even tell where the piston ended and the wall began. I sprayed some pb blaster penetrating oil and let it sit for about a week, but no improvements. I took the 4 bolts that hold each head out to take the head off (broke one or two bolts off i dont remember) but the head will not budge. You can literaly pick up the engine by the heads and they wont budge. So my question is....how can i take the heads off when the engine is so siezed? I cant find any pry-points but even if i could i doubt they would help. Also is their mutch of a bottom end in these types of engines and do they require any type of oil in them, besides the fact that it is a 2 stroke? I have never rebuilt a seadoo engine before but i am mechanicly inclined.
