FAE exhaust

[Hollywood]

Stumbled upon this today.

here is one on a 210 with a python...pretty interesting.. scroll down the pictures on this link.

That's got to affect the wake, but at least teak surfing will be much safer.

According to all the responses on the web site they say the wake is unchanged. Plus you can watch a under water video of the prop/exhaust, does not seem to change anything......

I'm confused. What is the point? Surely it decreases efficiency because of the smaller diameter (or so it appears) and the rapid bends in the exhaust as they come out of the boat?

And I would think the prop would rip it off after not too long.

The point is to not poison people with CO. If you've ever watched water come out of the boat when it's on a fake a lake you would notice that the exhaust does not really "shoot out." Backpressure is not really an issue with the exhaust systems in our boats. As they are already "free flowing exhausts."

Also it wouldn't really effect the wake... I mean, it's not exactly a huge obstruction, and chances are that the water where it sits is already turbulent due to the propeller.

I think it's a neat idea and probably works great. My main beef with it is that it looks HIDEOUS. I realize this is form following function, but ack, gag me. I'd have to cover the back of the boat with something while trailering just to hide that contraption.

One of their biggest selling points is noise reduction, which is something CC has luckily been working on for some time with innovative exhaust system designs.

I noticed the pic of it on the Python on WakeWorld and it definitely looks interesting! Per the top pic though, I wonder if it'd work on the more modern, single exhaust outlet Nautiques?

hum... when my boat is on the fake a lake it shoots out. Not at idle, but when it's got the power in it I can soak down my fence that is usually 10 or so feet away.

But never-the-less, interesting.

Sorry, I stated that wrong. The water pressure would be more relevent to the water pump.

And to comment on what I said earlier about it decreasing efficiency because of bend... Dragon, you are right, it is very free flowing. But any bends in the induction or exhaust also decrease efficiency. And in this case, there are three 90 degree, or at least it appears to be 90 degree bends.

But that's pretty neat that it doesn't mess with the wake. Definately a plus.

try holding your arm in the water a foot down and see how much pressure there is against it. i am not talking about hitting something, just the water pressure at speed. i would think there is a great deal of stress on the transom at the connecting point. i wouldn't be worried about the transome though, if the thing ever got ripped off an took some of the inside part with it you could sink the boat. imagine doing 40 with that thing hanging down! and i know it is tappered, but still!

[smay1981]

Speak I believe you are being a little dramatic....if you look at the picture on Hollywoods post you can see that the only part sticking down in the water is one pipe and the rudder and prop are right in front of it. So I doubt there is much transom pressure going on...I think youre thinking its like the wedge or something.
It looks like a good deal if you wake suft all the time and don't want the fumes in your face...IMO :grin:

I think you make a good point.

wouldnt't catch me using it (and it isn't the looks), no matter what the "testimonials" say.
