went out sat - boat ran rough at idle speed, it would cut off when I would try to take off. But when I could get going, once on plane the boat runs like a top real smooth. we went back to the dock and cleaned all the jets on the carbs.compression was good on all cyl. (125 to 145)we checked all cyl for fire all were good. finaly we started pullin plug wires and 3 cyl. were down whlie idleing #3 ,5and 6 were down while idleing. but the plugs were wet with fuel and the plugs were getting fire . Any help is greatly appreaciated

Thanks
