I went out on my 96 seadoo challenger yesterday and all of a sudden the boat shut off. I attempted to restart but got nothing. No click from the relay or noise from the starter. I turned the flywheel by hand so i know its not a seizure or obstruction. I also tried jumping the solenoid but got nothing. I know i have a full battery. Key post beeps twice when lanyard is put on. Please help

Anything else beeps?
So to lights work?
What if you try to start with the FNR selector in Forward? Does it beep more?
If you jumped the solenoid and it did not crank, there's a loose wire somewhere...that circuit goes almost straight to the battery on both sides. Follow those wires and check voltage. Maybe your battery crapped out and does not take a load at all. Check both positive and ground. Measure voltage at solenoid as you attempt to crank as well.

But you also said jumping the solenoid did not get the engine to crank. That's the easiest and cheapest issue to troubleshoot...
If you are having a hard time jumping the solenoid, try removing one of the wires and bolting both wires to the same solenoid side, then use the Main switch as the switch to test the starter. (and be sure to have it in the OFF position as you set this test up)

All fuses on the craft have been checked and are in working order. And to make the situation worse. It rained crazy last night and my battery died because of the bilge being used all night. Now my engine compartment is flooded. How can i start the engine to make sure all water is out......
First thing to do is to get the engine cranking. I still believe the issue may be simple.
take the plugs off the engine and get it cranking. Once you jump the solenoid the motor should crank. The circuit is simple and you can follow the wires with your eyes from the solenoid and the starter body to the battery.
Once you get the starter cranking, all water should be pumped out of the cylinders, if there is any in there (from the flood). Then put the plugs back on and it should eventually start. Run it like you stole it in the lake or other body of water you enjoy, as long as you can (1 hour will probably get most everything), to ensure all water that made it to where it shouldn't have gets evaporated away.

I worked on the boat all last night and couldnt get the starter to crank. The lead on the relay that goes to the starter is constantly hot even though the start/stop button is not being pushed. when i hook up 12volts and a ground directly to the starter it doesnt even crank. what would cause this. do i need to replace the relay and starter. i was able to take out the spark plugs and hand turn the engine to confirm that there is water in the engine. i need to get this engine turned over fast... please help
The button is not stuck, since you could get it to beep. Maybe the solenoid failed closed and fried the starter? Are you sure the solenoid is really stuck closed? Chec continuity between the two sides of the solenoid with the main switch off. Ought to be infinite resistance. If there is continuity you need a sstrter and a solenoid.

If you have a hot battery, and jump the solenoid's main cables with no response, pull the starter. Once you have it out, you can ground one of the mounts and apply battery power to the input. It should try to engage and try to jump out of your hand.
If this does not happen. Bad starter.
Why would a starter stuck in the engaged position cause a the engine to die? Well, starters are similar to generators, so in theory, if stuck and spun at high rpm, it may generate high voltage. The mpem shuts off at 18VDC to prevent electric shock at the DESS post. In turn, your engine dies.
How to test the start switch, break out the ohm meter, find the start button connector under the dash, or probe the wires with sharp meter probes. It should normally have infinate OL or high resistance. When engaged, it should have less than 2 ohms of resistance. Actuate the switch several times, in different amounts of pressure, speed, ect... You are looking for the switch to stick, or show a strange resistance reading.
Also, when the starter has problems, and the engine does not start, the mpem will give up and remove your control of it, until it is reset. I learned this when I had a dragging starter. That may be why you are not hearing the click, also, the solenoids of these boats are rather small. I can barely hear mine to begin with.
From your responses, I would order a starter from ebay. I know that is a dirty word on forums, but I have bought two new from emsglobaldirect for $65.00 shipped to my house. One has been in service for 2 years, and performs like new. The other is in my Sportster and is excellent. They also don't charge for cores.
It's weird that no-one found it strange that your boat had a lot of water in it from sitting in the rain overnight. You may need to check the floor drain/hose for leaks. You can also put the plugs in and fill the engine compartment with a water hose untill you see water coming out of the boat somewhere. Once you find where it is coming out, you will have have found where it is coming in, when it is in the water.
These things are well designed to shed large amounts of water, mine has sat through a rough storm with little to no change in the bilge. However, I do have a slow leak that I've been to lazy to find, and the boat will take on half a gallon or so from soaking overnight.
