Has Fresh Air Exhaust (FAE) changed your wake?

I have to admit that it looked a lot cleaner before when you could only see the stripes of the hose clamps against the black tubing and you didn't really see the aluminum angle "attached" to the tubing. But this way it's even more bombproof than before.

I think I could have easily gotten away with just the Stainless steel extension on the plastic exhaust output flange, but I figured I might as well over-build it since it failed twice before...

Alternatively, I could have used some kind of U-bolt setup instead of the hose clamps, but I'd already bought those and they seemed to be holding quite well. Really you won't even see the hose clamps attaching the tubing to the aluminum angle bar unless you get up under the platform and look...

Oh damn that should do it! If it comes off now, physics were some how broken.

Here is the wake at 30mph for skiing. (on rougher water)

And with the surf wave, you have no idea it has anything other than the quieter and the lack of fumes.http://i1070.photobucket.com/albums/...psh5zganah.jpg
This is with my wife driving and my son on the non-surf side.

Looks great man. I am redoing mine when i pull my boat out. I now know what i need to do. Mine is also acting like a trim tab and messing up my wakeboarding wake. Did you oval the down pipe at all?

It's probably something I'll do in the off season. For now, it's working. I did end up having to cut an inch off the bottom of mine because of the drag actually putting enough leverage to pop the rubber couplers off the exhaust flanges. The real FAE actually ovals down to less than 2" wide!! that's a HUGE difference from my 3.5" ABS. I know if I used PVC I could heat and oval it, but I tried to heat up my ABS and oval it using my bench vice and a heat gun and it didn't seem to do anything. I will likely get some aluminum for the downpipe and make it more oval. But for now it's working. The extension on the exhaust flange was the ticket for me.

Trayson, you are the king of DIY. That is amazing!

I am going to use a 4to 3 inch 90 out of the stock exhaust. The 4 inch slip perfectly into the stock lip and then i just rivet it dirctly to it. It all makes sense in my head. I will post it when i get it on in a couple months.

are you talking about simply having a downturn of the stock exhaust outlets so that you'd have two pipes just sticking down in the water? or are you intending on doing what the FAE does and join them together so that the downpipe is in the prop wash?

Doing the the same as you. But not using any rubber at the boat. This is what i had. It worked great but was draging in the water when up to speed. So i found some adapters that will algle it up much like yours. https://uploads.tapatalk-cdn.com/201...4813bbdb38.jpghttps://uploads.tapatalk-cdn.com/201...bafd5b4bde.jpg

FYI, the TEE that you used was way too wide for what I was trying to make work on mine. But getting the one with the screw fitting on the center of the tee was great. kept it compact and made it so everything fit. I think it's called a cleanout tee. so if you come up constrained on width, keep that in mind.

Look forward to seeing what you come up with,

Right on. I did have to cut a bit off each side for it to fit in on mine. Not having it on now i do miss how quite it is and the fumes are better unless im idling at 5 or under. Well worth making one that wont effect the wake. Thanks for the feedback.

Well here is my contraption. In retrospect i might have been able to go straight out instead of up. Im sure the new plate would have kept the water from hitting it. But really wanted to go through the plate to keep the spray from the down pipe to a minimum. Not the best looking but should work well. https://uploads.tapatalk-cdn.com/201...36e47e74c5.jpghttps://uploads.tapatalk-cdn.com/201...ae94cd2438.jpg

Wow, that's crazy! Keep us updated. Looks like your wallet plate is fixed?

You may want to read do that, probably fill up with water when idling.

Yes mine is a fixed plate.

Do you think it will be a problem? I saw a few on the fae site that angle up quite a bit. And is that much different than the one that swoops up in the post above that trayson biult. Now im worried...

Not trying to knock your design, did you think of routing each exhaust to turn outside and then down? Two outlets that went around the plate?

Ya. I quess i could have had the two pipes turn down and go through the plate. But i figured one thing stiking in the water is better than two. And really like the idea of going through the plate. Hope it works. I was trying for somthing simalar to the centurion silent stinger. I appreciate the comments.

Angle up a little bit yes, but 90 bend vertical is a different story. I would think it would trap water between the riser and the bend, not horrible but kinda like sticking a potato in your exhaust.. �� Drill some holes so the water can drain or redo it and have the pipes come straight out then down.

Got ya. So your thinking it wont have flow to push the water out? I was concerned about traped water when i pull it ou of the lake but didnt think too much about in the water. It sits at our dock all summer. Lake is still frozen so i can't find out right now but i will follow up.

Don't think it'll stall it or anything bad per se, just might restrict the exhaust giving a little less performance. Also when you pull the baot out that water would be trapped. Add some holes so it can drain.

Good info. Thanks

I dont think it would restrict the exhaust any more than normal since the water in there will be applying the same amount of pressure as would normally be applied by the water pushing the exhaust flaps closed. Your exhaust manifolds already have water flowing through them anyways. I do agree that normally it all drains when the boat is removed from the water and having it turn up like that will cause it to retain water. Might get moldy and stinky.

My thought is that the exhaust will actually flow better due to the venturi effect. The stock exhaust has no restriction when on plane, other than the flaps themselves and the restriction inherent in the exhaust. However, with the flow of water over the FAE, it could actually create a venturi effect, much like aircraft jet pumps.

For anyone wondering my fae worked great. No troubles at all. Still have a little wash on the wakeboard wake but not bad. Sound and fumes def better.

Absolutely nothing that I can see.

Mine has a weep hole drilled in by FAE, right next to the flange where it bolts through the hull.

Mine too. Found that out when I was trying to catch the antifreeze coming out the exhaust. [emoji23] Ended up draining out onto the wake plate and ground. Oops.

Question for "Trayson"

how did u make that metal/pvc adapter to your exhaust ?

Trayson ;

Question ... Did you drill a "drain" hole so trapped water could escape ? I just finished same setup as yours and read different post about a drain hole ? Thanks in advance.

Did you keep your "Flappers" or just remove them ?

Didn't keep flappers.
No weep hole.
Found aluminum pipe that has the same outside diameter as the inside diameter of the screw in clean out tee fitting. Sealed it with gasket maker.https://uploads.tapatalk-cdn.com/201...e30e3ec580.jpg
