my old boat had twin cummins "B" series... I used to roll down the window
of my car when I was at a red light next to a Dodge diesel pickup just to
hear the sound!!! now I have 671s and their sound is not as distinctive
as the cummins...


It's amazing that if you hang around diesel powered boats long enough you
get to recognize and identify the engine types by sound. I can recognize a
6-71 when it fires up 10 boats away.

The Volvo engines in my boat also have a distinctive sound ... in part due
to the fact that the engine room is totally sound insulated. You can hear
the exhaust and, as you throttle up, the turbos spooling, but no diesel
knocking sound. In fact, it sounds like a Greyhound bus inside ... sorta a
turbine sound due to the turbos. The engines sound very remote while
underway.

The Egg Harbor had CAT 3126 engines that have got to be the loudest things
I've heard in a boat that size. They had turbos, but you could not hear
them over the engine noise.

I've always thought the Cummins in the Dodge pick-me-ups sounded
"better" than the Powerstrokes in the Fords. But I have nothing on which
to base that, other than how the sounds hit my ears.

Totally different sound. The Cummins is a six, the Ford is an eight.
Ford 6.0L engines have a very distinctive sound when slowing down. Not
really a rattle, but a strange sound that no other diesel I've heard makes.
