I am buying a 48 Navigator with under hull exhaust when the boat gets to cruising speeds it jerks every 2 to 4 seconds even in calmer seas. I was told it is because the air expelling from the exhaust system gets trapped momentarily
beneath the hull and it creates the change in sound and a little jerk or leap through the water. Anybody care to respond on this issue. My last boat was a 62 Mckinna with under hull exhausts and never noticed this movement The engines are running smoothly and shafts and wheels are in alignment and perfect pitch.
