I have a 2003 seadoo gtx 4 tec and all of a sudden it would miss bad at high rpms. I did a full tune up and still the same problem. Now it will do nothing. Getting 2 beeps and the starter tries to roll over but will not completely roll over. It never over heated but would say oil temp and drop to the low rpm mode. I took it right back to the dock but it never fealt hot. HELP!!
