Just sound like they are ready to fly apart at any time? Mine is running good, pluggs are a nice color, good compression and fire on all cylinders, but it just sounds sketchy. I have a buddy with an 88 special Johnson and it sounds like death too. This is a 200hp Merc Black max by the way. WOT sounds great, and acceleration is great, just idle sounds somewhere between a steam engine and a top fuel dragster. Any other opinions?

While they do all have a staccato often erratic sounding low rpm cadence the Merc two smokers are the worst offenders I have heard. They remind me of my 454 Chevelle when I put in the high lift cam. My 150 Black Max sounded the same and everyone I have heard also.
Sounds cool, when I grabbed the binnacle I used to pretend I was shifting a Hurst shifter

They are real loud when the cowling insulation and the intake cover have been removed.

you would probably have to get a DI 2 stroke (with the opti as an exception) for it not to sound like a top fuel dragster. You should hear a merc race 2.5 outboard engine. That thing sounds wicked. Its hard to describe.
