    Question on DESS

    When was the DESS key put into Sea-Doo models? Is it normal for a 1996 Sea-Doo SPX to have a standard post kill switch? Is it normal for a seadoo with a standard post kill switch to have a MPEM with the wire for the DESS application? Any help would be greatly appreciated, thanks

    Do I have DESS key?

    I have a 2012 Challenger SE 210 and the lanyard is a basic style (no chip). Does the key have a chip or just a fancy key? Is DESS only involving the lanyard or if the ignition key has a chip is there a way to tell? It looks a black cup with a key in the center. Hard to believe there are any...

    07 GTX Std starting issue

    I have a 2007 gtx std that is having an intermittent issue "waking up" the ECU when I place the lanyard on the DESS post. My first thought was that the DESS post and or lanyard were bad. I pinned out the wires from the DESS post at the connection under the front compartment and it ohms good...

    Seadoo 3d starting issues

    Hi new to this forum. Picked up a seadoo 3d rfi about a year ago now. Was out riding it a few weeks ago and when I stopped for a while and went to restart I was only getting a jolt from the starter motor (doesn't turn engine over). On further examination the motor would turn over and start when...

I've unplugged the stator and pressed the button, and it still blows that way. Ive disconnected the gauges from the computer and pressed the button, it still...

    nothing happens when I attach lanyard/DESS

    Hello guys, I’ve got a seadoo RXP from 2004. A few months ago a very weird problem showed up. When I put the DESS on the DESS-post, literally nothing happens. No bleep, no “seadoo” on the screen. Just like the battery is disconnected. And sometimes, when I leave the key on the post, after a...

    If you don't want to read my long winded story below then please just answer the following question: Can a bad DESS post cause the engine to backfire while riding in the upper RPM range, push out and bend the rotary valve, scrape up the RV cover, and then cause the engine to quit? If you...

    96 XP - DESS changed behavior. Suddenly, have to press Start before it sees the key.

    First post here, glad this forum exists. I have a 96 XP that's worked fine for the 12 years I've owned it. Always just put the DESS lanyard key on the post, beep-beep, hit start. Always. Boat runs great. This weekend, I started it on the trailer for a few seconds in preparation for...

    Sea Doo Friends, I would appreciate your advice on a problem with my 96 XP. I pulled the ski out for the first time from winter with a few problems. I knew when I put it up I had a problem with a stripped shaft or PTO. When I first tried to get it to start it would not turn over. I came to...

    '96 Challenger... Wierd Starting Sequence!?

    Everything has been fine for years. Went to start the other day, put key on and got the single "error" beep...and obviously couldn't get it to engage the starter. I'm pretty sure that the DESS key was working or I guess I wouldn't have gotten the error beep. Now, for the weird part: I take...

    RXT instrument cluster & relay always on

    My RXT had been sitting for a while and the battery was dead. I put a charger on it while it was still connected. Looking back that was probably a bad thing to do :( So I did disconnected the battery and finished charging it. Now whenever I connect the battery I can hear a relay click on and...
