i have a 96 xp w/ a starting prob. when i put the key on i dont get a beep 80% of the time. when i hit the start/stop 6-8 times i get 2 beeps then nothing. dash lights on & off. after messing w/ it i can get it to act normal. once its working if i leave the key on its fine. im thinking i might have a prob w the electronic board in the white sealed box. was hoping for input before i go to a dealer.
 
I believe you modelis the first to have the DESS,(Digitial Electronic Security System). Here is something to try first.I would start by cleaning the Post on the safety lanyard. It is beeping and saying it isn't connecting to the Mpem, (Multi Purpose Electronic Module) It needs to beep 2 times to let you know it is ready to start. Clean the post and cap with soapy water. Don't use any grease of lubricant on it as it needs a clean connection to make contact. Connect the lanyard to see if it is making a connection. 2 beeps and it's ready to fire up.
Here are some teste to do if it didn't help cleaning it;

DESS System/Safety switch post/ lanyard

Engine start/stop switch verification;
Disconnect the Yellow/Red wire of the start/stop switch. Using an ohmmeter, connect test probes to the Yellow/Red wire and to ground. Measure resistance, it must be an open circuit (switch is normally open). Depress and hold switch, the ohmmeter should read close to “0” ohm.

Safety Lanyard Switch Verification;
If 2 short beeps are not heard when installing the safety lanyard, disconnect the switch wires.
Safety lanyard removed;
connect the test probes to switch Black and Black/Yellow wires. It’s an open circuit, there should be no continuity.
Connect one test probe to the White/Gray wire and the other test probe to the switch terminal. Measure resistance, it should be “0” ohm. Connect one test probe to the Black wire and the other test probe to the switch ring. Measure resistance, it must be close to “0” ohm.
Safety lanyard on switch; connect the probes to switch Black and Black /Yellow wires. Measure resistance, it must be “0” ohm.
Timer Verification;
The timer is integrated into the MPEM. Always confirm that the fuses are in good condition. To confirm operation of timer, remove the safety lanyard from switch. After 5 seconds delay, depress start/stop button once. The timer should stay on for 33 seconds (for example, the gauge(s) will be activated) and than turn off.

i did clean the lanyard and post which didnt appear dirty. it worked the first time then acted the same again. after i cleaned it again it worked. but not all the time. is it possible the key contacts are worn. thanks for your help
 
Your seadoo does have the dess correct? Then try the tests I just gave you. That's the only way to check it, and save you like $40.00 for the lanyard and the 35.00 for the post and $50.00 to re-program it.
