One of my customers was very sensitive to diesel exhaust. He converted two Bertram’s to dry stack exhaust by running it all the way up the tuna tower.
The first one, Shooting Star, is still in service as a charter boat in Fort Lauderdale. The second larger Bertram caught fire in Biscayne Bay as it was returning from the Bahamas.
I don’t know if the fire was related to the exhaust or not.
