WHEN I HAVE RUN THE BOAT FOR 30 MINUTES OR SO, AND STOP FOR AN EXTENDED PERIOD, (30MIN. TO 1 HOUR), THE BOAT STALLS OUT RIGHT AFTER I GET IT UP ON PLANE. THE BOAT CAN SET ALL WEEK IN MY GARAGE AND WIIL START RIGHT UP AND RUN ALL DAY WITH NO PROBLEM. IT RUNS FINE EVEN WHEN I STOP AND GO ALL DAY WITH A SKIER. THIS ONLY HAPPENS WHEN I STOP AT THE LOCAL COVE FOR LONG TIMES AFTER RUNNING THE BOAT HARD. I HAVE REPLACE THE FUEL PUMP AND THE RELAY. EVEN THE CONECTORS FOR THE RELAY (THEY WERE CORRODED). ONE OTHER THING. AFTER I GET IT STARTED AGAIN, (THIS CAN TAKE SEVERAL MINUTES OF CRANKING), I GET A SMELL FROM THE EXHAUST LIKE YOU WOULD GET FROM A VERY LEAN RUNNING ENGINE,(OXIDES OF NITROGEN SMELL). AFTER IT STARTS IT WILL RUNN FINE FOR THE REST OF THE DAY. I AM A PROFFESIONAL AUTOMOBILE MECHANIC BU HAVE LITTLE EXPERIENCE ON BOATS . SEAMS LIKE VAPOR LOCK TO ME.  DOES ANYONE OUT THERE HAVE ANY IDEAS ABOUT THIS AND HOW I CAN FIX IT? __________________ 1998 HORIZON 180 W/ 4.3 GL. Back to Top
