Dumb Question
 

I know this is a dumb question, but since it's 50 degrees here, raining, an looks like November outside I figured I'd be the first "winter dumb azz question thread".

I was trying to avoid the NFL crybabies and surfing the interweb yesterday; I got sidetracked like 47 dozen times and ended up watching a YouTube video of a Skater (I think - don't really remember) with Merc 1100's which was idling at the dock.

The boat at idle was QUIET.

Do the turbos really muffle the sound that much ? Or was something wrong with the sound ?

Post the video. Turbo motors are much quieter than a 1075sci, but I still wouldn't call them quiet.

Was it a square transom, or was the exhaust under a bustle? The bustle really quiets things down, especially if it's mostly under water.

Turbo motors around the docks are much more quote than the past 1000HP motors, especially if there is a Bustle on the boat. Once open up though the sound is all there.

A turbo has a side benefit of acting as a muffler. I have a few friends that run an open exhaust on a street car. It's not quiet like stock, but not that loud either.

At the 44 second mark you hear the merc turbo motors in the 42X with big block stuff before and after it.

They also have Catylitic converters making them quieter, my buddy has 1350's in his 52 Outerlimits, I think its quiet ...

at 1:43, that was us with 1100 Turbo's in the Sonic. My 525's were twice as loud.

The 1350's have catalytic convertors? I thought anything over 500HP didn't require them why the heck would you do that on a 1350?

I didn't think these motors had those either.

Pretty sure only the black motors have cats. Anything Merc Racing does is exempt. Even the 520's have the 496-style manifolds/risers on them with no cats.

I think that's a misleading video, and the angle is bad to get good sound from the transom. The audio quality is terrible period, almost like someone had their finger over the mic. That may be a Go-Pro video as well, which they don't have the best sound recording. That, and the transom is pointed away with twin bustles, aiming all sound waves in the opposite direction, as well as there is nothing behind the boat to bounce the sound off of.

My Go Pro captures sound just fine. The turbos kill the sound.

Sometimes I wish mine was that quiet. (eh not really)
