I hooked up my seadoo rx to the hose to day to flush it out and I started the seadoo, ran to the hose and turned it on, then my seadoo starting REVING out to the max it seemed like! I turned the hose off real quick and pulled my key off AND THE SEADOO KEPT RUNNING! TOOK THE PLUG WIRES OFF AND HELD THEM AWAY AND IT WAS STILL RUNNING, THEN STARTED BEEPING SHOWING OVERHEATING, I then choked it and it died... Why would it still run with no WIRES even on the plugs? CAN ANYONE HELP?

They run away because they are too lean for the amount of fuel being put into the motor. They get too much air, and not enough fuel. 951 engines will run away even without air leaks or lean condition. They will run away if the idle speed is set too high. You must have slack in the throttle cable at the idle position, and to set the on-hose idle speed to 2800 rpm, 1400 or so in the water.
If the engine continued to run without the electrical system (i.e. the lanyard was removed), the fuel has to be getting ignited from somewhere. Likely you have some carbon deposits in the combustion chamber that are getting hot enough to ignite the fuel. Carbon deposits are very common in two stroke engines. In addition to rebuilding the carbs, I'd suggest decarboning the engine using your favorite method. You'll likely need to replace the plugs afterward, but you should do that annually anyway.
Ever hear the term "Glowplugging" the tip of the sparkplug gets red hot and ignites the fuel without electrical imput to the sparkplug.
This happens when the motor runs too lean of an air/fuel mixture. Too much air, not enough fuel. Fuel keeps the combustion temps within a certain safe range. Take away the fuel just a little bit and you have a glowplugging motor that revs to the moon ! You did it, Choked it! Thats only way! Bills86e
