I just took delivery of a 2005 285ssi with a captains call exhaust. When i hit the switch to quiet it, it did nothing. Then i Found out that NH law requires switchable exhausts to be disabled. Problem is it is disabled in the loud setting. I had a tech manually close it and it did get quieter, but still has exhaust coming through the hull. He pushed it as far as it would go. He thinks the diverters may be worn? No disrespect to those who enjoy the sound, but we really prefer a quiet exhaust through the props. Any input greatly appreciated!
