Seadoo GTI 720 not start

[Vandyck]

hello all.

i got a problem with my seadoo gti 2005, first of all, last night i charged my baterry, because there was dead, i did out of the pwc. Today i was in the lake, it was all normally, but after 10 minutes, my pwc started to die when i keep in slow running and try to go to full acceleration, now he doenst start, doesnt fire, but when i spray directly to air filter, he fires up and die again.

Can be the baterry? i tested it, it was with 11~12v but when i try to start got to 9v.

sorry about my english, some words i dont know exactly in english.

thank you

Yep, sounds like the battery, the voltage is too low for the MPEM to operate.

Yep yep. Bad battery.

Once you get a new one and charge it up NOT hooked up to the ski you should be good to go.

Once you get it running check to see what your charging volts are. Just to make sure the ski is charging the battery.

Hi..

I bought a new battery, charged it...but the ski keeps with the same problem, now he starts, but if i left in slow running, after few seconds, the ski dies...and any moment if i try to accelerate, dies too.

I changed the sparks too.

Now i really doesnt know what can be

thanks

Sounds like your carbs need to be rebuilt. Do you still have the grey "TEMPO" fuel lines? If so, they need replaced.

Hello.

No, i dont think so...Its 2005

i will buy a rebuild carb kit

Make sure it is an OEM MIKUNI carb kit. No aftermarket parts.

And just lift the seat and check the fuel lines. if they are grey, it does not matter what year they are, replace them. best 50$ you will ever spend.
