  • Product Info

    Frequently, after a day on the water, we feel irritable, nauseous, or have a headache. We typically blame the sun, the wind, the beer, a hard fall, or simply exhaustion but we may be experiencing the subtle toxic effects of carbon monoxide.


    How does Fresh Air Exhaust work?


    Fresh Air Exhaust (FAE) works by injecting the boat’s exhaust gasses into the propeller wash to move it away from the boat. This is done by connecting the FAE to the existing exhaust outlets. Consequently, the propeller wash pushes the exhaust gasses away from the back of the boat, where it surfaces anywhere from 30 to 90 meters behind the boat; and greatly diluted.  This is similar to outboard engines that have the exhaust exit through the boat’s propeller.

    The Benefits


    Reduces carbon monoxide by approx. 90%


    Carbon monoxide is a lethal gas that is produced in the engine exhaust and can accumulate, even in areas that appear to be well ventilated. Many people have been on a boat and later in the day felt lethargic or had a headache. They typically blame it on the sun, food, beer, etc. The complaints may be due to carbon monoxide poisoning.

    Because carbon monoxide is colourless, tasteless, odourless and nonirritating, it can overcome the exposed person without warning. Children, people with pre-existing heart and lung conditions, people with asthma, and the unborn child are especially vulnerable. The effects of carbon monoxide are cumulative; the longer your exposure, the greater the health risk.

    Reduces exhaust noise by approx. 50%


    Boat exhaust noise with a Fresh Air Exhaust is typically reduced by 4 to 6 decibels; this is considered a 50% reduction in perceived noise levels.

  • Options

    Fresh Air Exhaust are available in 4 designs, suitable for a many dual and all single exhaust inboard boats. 

    Original 3 Piece Design

    The Original 3 Piece Design is available for many dual exhaust inboard boats. This design has the lowest delivery cost because as it can fit in a smaller box. It is also the most adjustable; though this is seldom an issue.

    One Piece T Design

    Some prefer the 'cleaner look' of the One Piece T Design. It is available for many dual exhaust inboard boats.

    One Piece Y Design

    The appearance of the One Piece Y Design speaks for itself. It is available for many dual exhaust inboard boats.

    Single Style Design

    The Single Style Design is available for all inboard boats with a single exhaust outlet. The secondary mounting for most boats will attach to the trim tab hinge or the drain plug flange.

  • Features


    Finish - Brushed Stainless

    Welds - Standard


    Welds - Blended

    Blended welds are polished to blend the weld for a smooth finish. This only applies to the outer, most visible edges of the elbows and do not hide the weld of the down pipe.

    Platform Quick Release (PQR)

    On most boats that have two exhaust outlets FAE will also attach to the swim platform. If you remove your swim platform for storage or frequently remove it to polish your boat, the Platform Quick Release is a necessary option.  The PQR has 2 quick release pins to quickly disconnect the swim platform from the FAE.  Even if you only remove your swim platform once a year you may wish to include the PQR because the hardware used to mount the FAE to the swim platform can be difficult to remove once installed (stainless steel nuts and bolts has a tendency to seize once tightened).

    Quick Release Lever Clamps

    In combination with the Platform Quick Release (PQR), the Quick Release Lever Clamps allow you to completely remove your FAE from your boat.  This is only necessary if you require complete removal of the FAE for storage purposes.

    Do you want to make installation easier?

    With the side mount option you mount your FAE to the swim platform brackets; this is accomplished by drilling a pair of holes into the brackets. If your swim platform has tube style brackets, the side mount clamps onto the tubes. Without the side mount option, you have to remove the fibreglass swim platform from the brackets to drill the bolt holes; basically a pain in the rear and an hour or two longer. The side mount option is available for most boats, please confirm when ordering.

    Does your boat have a Fixed Trim Tab?

    If your boat has a centre trim tab that is not adjustable from the driver’s seat, then you have a Fixed Trim Tab. The FAE database lists lots of boats that have a fixed trim. In case we don’t have your boat listed correctly, let us know if your boat has a Fixed Trim Tab.

    Boat Exhaust Flappers

    Inboard ski/wake boat exhaust systems are wet exhaust systems. During normal operation there is water in the exhaust pipes and muffler. The water is pumped by the impeller first into your engine. The hot engine water is then injected, at the aft end of the header, into the exhaust system. In other words, the water is injected into the exhaust system where the rubber hose begins. Without this water, the rubber hose begins to smoke in about 30 seconds.
