Hi, we are very close to pulling the trigger on a new engine
to replace our beloved Perkins
4-154 on our Peterson
44. Lots to consider but one thing I'd like to ask here is: has anyone compared the noise/vibration level of the Beta 60 to the Cummins 4B3.3M? I've fooled around on You tube but it's too hard to compare due to the different installations or even someone running the engine
on an open test rack.
So more realistically have any of you replaced your Perkins
4-154 with either of the above engines? If so how do you compare the noise/vibration level to your old 4-154? All three might be very much the same. However one friend with a larger Cummins said his really had the shakes below a thousand RPM
. While we are at it did your Beta or Cummins have more power than your old 4-154?
