seadoo gtx 2003 sc, getting beeps without codes - PWC Forum: The best hang-out for Personal WaterCraft enthusiasts

Hello seadoo owners...

I have the following problem...

When starting my seadoo 2003 GTC sc 185 bhp the pwc works out fine, no problems occur....After 5 minutes or more and hitting 60 mph with perfect accelleration I can hear a loud long beep (2sec's). when slowing down a bit I don't receive a beep, then hitting top speed again -->one long beep.
Then after 15 minutes I can hear the long (2sec's) beep more frequently about every minute or sometimes every 30 sec's. Again acceleration is perfect end top speed not a problem. It's getting anoying the beeping.

Then after 40 minutes or so my display goes out for only one second and is then back on....

Then next problem when accelerating to topspeed it seems that the fuel to the engine is cut of for 0,5 sec or so...after this very short period full power again...This only happens 3 times in one hour...

Again I receive no codes for what so ever, no led in the corner of the displays lit up, no notting (e.g. check engine, maint, sensor)...There is no alarm mentioned on the display.

Summary: I only hear long 2 sec beeps every no and then, no codes or faults mentioned on the display...

Any ideas? I am getting a bit crazy over here....Any suggestions are more then welcome as for the OEM Seadoo dealer doesn't knows SHIT...

Please Help ..

Typically the long beep is for either high heat due to low coolant or low oil level. I am sure you have checked both. There could be a problem that doesn't show itself until a period of time at WOT, then if you back off the condition goes away. False alarm may be a bad sensor. My Seadoos are newer than yours and have intercoolers. So I am not familiar with your year and model. You could try calling my dealer J&J Watercraft @ (302)655-4957, bear in mind this is a very time of year for dealers so you may have to leave a message for a call back. It is strange that there is no code or indicator warning.
