My Westerbeke 8.0 BTD currently exhausts through a lift muffler and out through the hull, above the water line. Previous boats I've owned have had much quieter lift systems. I have been staring at the space in and around the exhaust hoses and muffler and am wondering if installing a separator like Centek's, for example would be worth the time, expense and scuffed knuckles. If I could add a gen-sep to the existing system (of course making sure it would work with the machinery) would I be happy with the result? I just find that the gen exhaust should be quieter since we spend much time in the cockpit which happens to be near the exhaust port. Has anyone had any experience with reconfiguring their generator exhaust or adding a separator? Looking for both pros and cons.
