Hi William, my name is Jason.

The check engine light will flash a pattern indicating a code. Can you check that for me and let me know what code/pattern it is flashing.

Customer: replied 1 year ago.
No flashing pattern code - light simply on accompanied by buzzing!
Expert:  Jason replied 1 year ago.

Is the oil or over-rev light light at all or are those not lit?

It should be flashing a code, that is the way it normally is supposed to work. because it's not doing what it is supposed to do this isn't something I am going to be able to help you with, and you will need to bring it into the dealer.

Good luck!

Hello William, my name is***** will assist you.

I you havent already done so, replace the water pump impeller. This warning buzzer without a flashing light, could be indicating to you that the engine was hot. The pump is a wear and tear item and should be replaced every tow to three years. You listed your engine as an 08, so it should have already had several impeller changes. After you get it replaced, go out and run the boat to see if the problem is solved.
