Only when using an exhaust /water separator the exhaust may
have a length up to 7,5m after the water/gas-separator.
However water traps should be avoided as the fumes still
contains water and this should not accumulate in bends (refer
to Figures 12 and 13). An additional outlet exhaust muffler
close to the hull outlet will help further to reduce noise
emission.
If the M-GV4 Piccolo and the exhaust system have been
installed correctly, neighbouring boats will not be disturbed by

outlet noise. With the "super silent" exhaust system, GV-4
noises are almost inaudible. For optimal noise reduction, the
sea water outlet from the exhaust/water separator (centre
outlet on the unit) should be installed below the water level to
eliminate noisy splashing of the effluent sea water.
The through-hull outlet for the exhaust fumes should not direct
the fumes directly toward the water surface as this will cause
excessive noise (refer to Figure 14).
