I hav an outboard jet on a jackplate. I have built 3 different spray plates fir the back of the boat to stop the spray.. I can't get it right! The one I have on there now is 12" wide and goes over the intake foot when the motor is trimmed down all the way. Sprays out both sides! If I trim it up at all it sprays 6 ft in the air!! What can I do?
