Hi, i own a sea doo speedster 1800 1998 with the twin rotax 787cc. It ran perfect last year but this spring i took it out for a ride and it ran fine for about 30 min or so. After 30 min i took it back to the marina.... or tried to for both my engines totaly died out just like that no beep no nothing like i pulled the dess. When the engines died i waited about 30 sec pull the key put it back put in neutral and it started back like nothing happened it did the same thing over and over again until i dock the boat. I'm checking for the ground wires but i'm new to boat électrical system so if any of you has an idea about my problem thanks for dropping me a line.
