How did I NOT SEE missing oil tank when buying 97 Seadoo XP. 

I use a Maddox Compression kit from Harbor Freight. I bought a Pittsburgh kit first, but it was so inconsistent.

If you don't have the key, there is no way around it. You will have to have another programed.

My Kawasaki starter got stuck in the engine and it was the 2 o-rings. I believe the previous owner replaced the original o-rings with larger ones and then shoved it in. I had to use a pry bar to get it out. If all else fails, you could pull the stator and flywheel and push the starter out.
