There are moments in the firing order that cause two exhaust pulses to be produced from the same side of the engine, thus creating an irregularity in the sequence and spacing of exhaust pulses. Different configurations of engines differ in sound due to the values of the dominant frequency emitted from each motor.

Do mufflers get louder with age?

Long story short, aftermarket exhausts that equip mufflers with fiberglass packing will get louder over time – this is known as “muffler break-in”. With time, these glasspacks can wear out and get broken – reducing the muffling and making the exhaust sound louder.

Each pulse makes a tone, which combined with the other pulses forms a harmonic series. The same thing happens in all engines, but it’s the irregular firing sequence that gives a big V8 its distinctive throbbing sound.

In addition to applying the throttle quickly, make sure the outdrive or outboard is trimmed all the way in and the trim tabs (if present) are engaged.

What causes an engine to decelerate in a boat?

Picture the torque on the drive shaft and gears as the engine tries to accelerate the prop while the water suddenly decelerates it. In addition, the jostling and slamming of the weight of the engine cause stress on the motor mounts, transom and bracket.
