    Fresh Air Exhaust Review

    We're in the second year of ownership of our 2003 SANTE 210 (love it) and I'm getting down to adding some custom touches for what we do (mostly surf, some wakeskate, occasional wakeboard). Earlier I ditched the centre tank for a bag and plumbed it with an integrated bow sac and a new Johnson pump, I'm working on a custom tower light bar with 4 16W square LED "off road" style lights, and Friday I received and installed our new FAE!
    I've always dug the idea and have literally read 40+ glowing reviews of them and maybe 1 ambivalent one. I like fabricating things myself, and I have a TIG welder, but after examining the cost, time and materials to build my own FAE, I pulled the trigger on a pre-made one. I have two kids, so free time to dink around and fab up parts is at a minimum, plus materials were looking around $150 and at least a full day of labour (time that could be spent surfing!).

    FAE's measurement sheet was easy to follow: I guess each Nautique is lovingly hand crafted and thus slightly different, so Nautique FAE's have to be built to order. I was quoted between 10 to 14 days for fabrication, and they shipped it after 14 days; not bad considering its probably the peak of their sales season. Shipping to the Great White North took a little longer than expected, and both USPS and Canada Post's tracking details left a lot to be desired. It seemed like the package would sit somewhere like Chicago for days at a time. If I were to re-order, I'd definitely opt for FedEx or UPS.

    I tore into the project on Friday morning and it took about 2 hours total, with no major hiccoughs. The instructions were crystal clear, and I totally understand the challenge FAE faces: build a custom product for a boat you can't see or test fit on, and make it easily installable by the consumer. I might have built the support for the pipe differently, but again, I have the luxury and test fitting and having fabricating skills. A nice touch was including a new centre support for my swim grid: much beefier than the old one. Set aside at least two hours for the install, as some drilling and cutting is necessary, but again, the instructions couldn't have been clearer. It may look in the photos like the bracket is off centre and not right, but my centre support is very far left of centre, making the distance between it and the exhaust hole pretty tight.

    My one complaint (minor) is the flimsy plates used on the bottom of the u-bolts under the swim grid. As you can see, when torqued down, the plates deflected and with the reduced purchase, the square tubing brace was allowed to rotate slightly under load and the exhaust flex pipe popped off the boat side of things. I solved this by making two new pieces out of the scrap square tubing from the installation. I made two "U" channels by cutting the tubing lengthwise, then drilling it to accept the U-bolts. MUCH stiffer, pipe is way more sturdy and virtually no deflection when the U-bolts were tightened.

    As for performance, it's everything I expected. Huge noise reduction, especially for the surfer, and although I don't have data to back it up, I'm sure reduced CO exposure. It's worth the $420 to not have a 6 litre V8 roaring 8 feet from your face

    Great upgrade, totally recommend.

    I have to concur about the noise reduction. The duals on the Python were so loud that I nearly sold after buying without trying. The FAE made a real "sleeper" out of the beast and the CO2 reduction was a bonus. Dropped 23 dbs. I had to fabricate a fiberglass lip onto the existing Nautique exhaust ports to keep the FAE tubes on the boat as the supplied hardware just wasn't up to the job. They kept blowing off the back. Also, I have just started noticing that the enamel on the lowest part of the stainless down tube is beginning to "chip" away due to water pressure.

      Ian, I have the Python dual port exhaust FAE too on my 2002 SAN and had a massive amount of spray when I installed it a few years ago. I had to trim 3 inches off the bottom to make it usable. It's still a really messy surf wake compared to what it used to be but much quieter and almost no exhaust.

      Did you have the same experience?

        simplysanj.....Yes. The wake was a little "dirtier" but not too much. I am curious about your trimming off 3" though. How did you handle the oval slash cut on the original? Did you just straight-cut it or did you try to follow the original shape of the down tube? How did you touch up the paint finish on the stainless? Lastly, with the exhaust down tube now 3" shorter I would think you may have lost some of the benefit of exhausting straight into the prop wash. What was your experience?

          Interesting to hear about the surf wave being messed up on two Python boats. Does the wakeboard wake remain the same? I (and I'm sure the lake residents) wouldn't mind quieting the beast down a little bit but I wouldn't do it at the expense of the wakeboard wake.

            Quiet but still spraying, 3" cut off the bottom sprays onto swim deck

            I cut it at the same angle as the original using an air cutter. I then ground down and repainted the exposed edge with spray paint from a can (originally powder coated?). Over the years some of the paint on bottom of the exhaust has worn off. The exhaust effect was the same, the boat is quiet and the exhaust blows into the rooster tail and re-emerges somewhere behind the boat behind the surfer. Much better than the swirling accumulation that I had below and massively more quiet than it was even with baffles.

            The big difference was that the spray was now shooting up much steeper and most of it was caught by the swim deck. Still really messy but livable. I will be building a mudflap/tab of some kind to smooth out the mess directly behind the exhaust. I've seen a few of these done on this site.

            Have a look at the pic below.

              I'd be very interested in how the flap idea works out. Your cut looks to be a lot straighter than the curved cut I have on my FAE though.

                S_Kelly....I didn't observe any changes to the wake past about 20 feet. All the "mess" occurred in the surf section area for me.

                  Here's a picture of the bit that was cut off, the original port was curved and the new cut is just angled. I think that the curve is pure aesthetic.

                    This is Larry from Fresh Air Exhaust. I don't know the specifics of the FAE that simplysanj discusses above; how long ago his FAE was fabricated, but since it had the black finish is wasn't recent. We have shortened the length of our downpipe in general. We have also modified our compression die to make the downpipe a bit narrower. We have also modified the installation to prevent the rubber hose from slipping off the Nautique exhaust outlet as mentioned by SuperAirIan above. For the most part we get only a few complaints of the surf wake being disturbed and almost no FAE returned, even though we have a very liberal return policy. We also get very little feedback from customers about modifications. I like the improvement that dscoff used for the u-bolt backing plate and will probably make that improvement to future FAE. We really want customer feedback as we learn and continue to improve based upon your experience.

                      Hey Larry I'm really loving my FAE but your comment on making shorter now just wondering what your looking at now for length suggestions? Basically wondering if mine might be alittle longer than need be now? I believe in the past u suggested the pipe extend to about the middle of the prop?Click image for larger version

                        larry,

                        what is the shortest length possible and not have to pipe come out of water while turning. i would like to disturb the least amount of water with the pipe
