Sierra-Tube-Exhaust from SIERRA
Some larger V-8 engines that create a large amount of back pressure use exhaust tubes rather than bellows. This helps to relieve the excessive pressure and eliminate problems with premature bellows failure. In the past, the exhaust bellows would blow up like a balloon and cause the drive shaft bellows to rub against the yoke and U-joints causing holes in the bellows.

Gen-Sep Water Separator, 2" Diameter, Gas In/Out 2.0", Water Outlet 1.5" from CENTEK INDUSTRIES
Position the water drain from the Gen-Sep just below the water line to eliminate water splash, especially important for nighttime operation.

That water can then be drained to a hull fitting just below the waterline, thus eliminating excess noise often created by splashing and pulsating water flow at the exhaust outlet. A slight downward angle is required for both the exhaust outlet and the exhaust gas tube. Dimensions: 10.
