Back pressure in the leg of the motor is much greater when in the water. When on muffs the engine will run on a leaner mixture. Richen up each carb by turning the mixture screw 1/4 turn counterclockwise the first time. If this doesn't solve it , try 1/2 turn counterclockwise. Hopefully this solves the problem. ghostrider
