Customer Question
I have a 1986 Kawasaki...
I have a 1986 Kawasaki 750 jet ski. She runs great for long runs(up and down the Wabash River near Vincennes IN). Any time I run her donuts, starts and stops, it will run for about 45 mins then goes into a trolling mode, any gas and then she dies. Starts right back up again. After sitting for a day, it up and running again. Carb has been cleaned. Water does flow from the engine out the front, not a lot and very hot. Any help is greatly appreciated.

Hello, welcome to JustAnswer.

 

From your description, it sounds to me like you are over heating your engine. You need to check your coolant water hoses for kinks, pinches, or blockage. Very little hot water being expelled from the engine means very little water volume cooling the engine.
