Boat Noise Level Rating

[Spencer_Shultz]

Fellow waterski enthusiasts,

I’m trying to find the noise level of a 2016 SN 200 5.7L. Would anyone happen to have that info?

You’ll see why I need it in a few months hopefully!

Thanks,

Spencer

I assume they want the decibels some distance from the boat?

[Spencer_Shultz]

@BraceMaker yes.

Contact Nautique, I'm would think they have that data.

[Broussard]

That is (or was) part of the towboat test. You might be able to find it in old towboat test reports.

My suggestion is find a boat and measure it. Went through this with snowmobiles a few seasons ago. Published data loses to a neighbor with time in their hands. Add a FAE and document what your boat is like at hole shot 10 feet away and then you have proof. In my case it wasn't us making the racket and we proved it.

@Spencer_Shultz are you worried about the boat being too loud on a private lake? Does your lake have sound restrictions? Just curious. I live on a ski lake, my house is very close to the water. On my lake there are nautiques and malibus. You can hear them but it isn't intrusive.

I live on a ski lake and I think the loudest part of the boat from shore is when the driver pulls back the throttle to stop the skier and shorten the rope. I know this sounds crazy but pay attention next time a boat is running the slalom course.

@skierjp - Not crazy, when you cut the throttle the water flow drops significantly so for a short bit the engine exhaust:water ratio goes up. Water is a significant 'muffler' of exhaust noise.

@skierjp try some downturn exhaust tips. As you come off the throttle, they drop below the waterline.

I don’t have a problem on my lake. I was just offering a suggestion. If you ease off the throttle when slowing down the boat is quieter. I have the new Ski Nautique so mostly all you hear is the water spray when it goes by.
