I cannot get my 1997 Challenger 1800 to Fire on either engine, The bilge light stays on the dash and the DESS will not beep (Chirp) ready nor will the Gas gauge show life. The motors will turnover with DESS in place but I cannot get it to fire. ANYONE HAVE ANY SUGGESTIONS, I'm about to lose it...

Hi - I recently purchased a 2004 SeaDoo RXP. After it was sitting in my driveway for about 8-10 hours, all of a sudden it started beeping 4 short beeps followed by a pause, and then 4 short beeps again. It did this continuously. I couldn't get it to stop, so I disconnected the battery. I...

Was hoping I could get a connection verified on this ski. It's the one inside the front compartment that is behind the access panel towards the front of the ski. It's the one that runs to the gauge cluster. I am having some elec. issues but the ski runs fine. I am currently not getting any...

give it a shot I know this is long but just lay out all i have tries thus far. old five amp fuse blows problem. checked stator and all good still blow fuse. put in used mpem. unit would not recognize either the key or the dealer program key. dealer said probably DESS post so replaced with...

So I got my first seadoo last week, a 1997 GTX. It won't beep or start with the lanyard. The gauges will come on when I press the start button. It will beep when I push the start button a short beep and a long beep. But when I put the lanyard on and off nothing happens with the original key and...

Hi. I bought a 2007 4Tec GTI NA. Engine was shot. Rebuilt the engine. All fuses are good. When I put the lanyard in, the display lights up for 3 seconds and disappeared, but the “SEA DOO” text stays on as long as the key/lanyard is plugged in. I checked the power relay, it does click/switch...

Hey guys the GTX turns over fine and strong, just no spark. Gauges work fine, and put lanyard on and no beeps.... is this the security system (DESS) kicking in or something else? in the driveway it started/ran fine, towed to lake and now this.

I have a 98 seadoo xps. I had a new key programmed that worked fine for about 2wks. I pulled the craft out of the water because it was running very sluggish. (Really needs a good tune up) I tried to crank it about 2wks later and I get nothing. There is no beep when I attatch the key to the dess...

Hey Guys Have an 03 GTX 4-TEC that went died on me. After alot of trouble shooting, from what I found on this forum, I was able to find the problem.. Went to launch the ski the other day and out of the blue, it was completely dead. I put the landyard key in and nothing, no beeps or gauges...

I am looking to buy a friends seadoo xp. he flipped it last year and ever since then it hasn't started. today I went to go look at it, put the dess key in and I heard no beeps. left my finger on the start/stop button and I heard a 4 second beep followed by 2 beeps moments later.. I checked the...

I just need some clarification of what runs on dess/mpem (and what would need reprogramming) by swapping out. In the front box of my 96 gtx it has mpem, rectifier, and starter relay. So i know the relay and rectifier should not have any impact if i was to swap those. Dess key?, Dess key...

So I have the same problem with my 97 XP as alot of other people have with the lanyard, It just shuts off when I am riding it as if I have disconnected the lanyard. And sometimes when it shuts off it will beep twice as if I have disconnected the lanyard and reconnected it, and sometimes it won't...

Have performed advanced diagnostic, 2 short beeps, will not start. Ski was working, kids shut it off out on the lake, went to restart, got nothing. yesterday couldn't even get any beeps, now getting 2 beeps. Using advanced self diagnostic mode pressing start/stop 5 times I get one short and...

So, I can get a spare DESS for my Speedster at a Sea-Doo boat dealer, but not at a Sea-Doo PWC only dealer? How does that make sense?

I am trying to figure out if I have a DESS problem, MPEM problem or maybe just a bad wiring. 1999 Challenger 1800 twin 787's Boat will start, and runs great. I do not have the speedo, or the fuel gauge when I start and runt he engines. Low oil light works, so I know that its not the...

Just bought a speedster and having issues with it. Only one engine will start and run. We have: Checked every possible fuse known to man-NONE blown Ohmed and checked continuity Swapped starters-Both good New solenoid Solenoid jump with turn engine over fine Getting continuios tone when...

I am suspecting my MPEM is dead but I am still holding out some hope that I don’t have to spend $$$$ to get a new one. I bought the boat used and it ran fine on the lake during trials. Get it home in the drivewayand had trouble starting it with an inability to get the 2 beep code(was...

My 1996 Speedster will start one minute and will not start the next. If one engine starts the other one will start, if one engine wont start, the other engine wont start. Sometimes I get beeps and other times i do not. Both Tachohmeters are stuck on 5000. Once i get it started and underway...

Hello, Last season I went to winterize my skis and the one(1997 GTX) would not start. It worked a few weeks before that and I decided to wait until this spring to fix the problem. This weekend I decided to start looking at the ski again and I am a little confused by the problem. I connected...
