- Does anyone have any thoughts on the exhaust note of GE's
- engines? They seem to have a distinct "chugging" sound, particularly
- at low speed. The problem I have is that the chugs seem to be too
- infrequent, coming on the order of once (maybe several times) per
- second, whereas the exhaust pulses from a four cycle V-16 at
- a few hundred RPM (idle) should come 30-50 times per second. I have
- also noticed that both the U18's and C424's in our area have
- a more rapid exhaust note than the big boats.
