    YES! And some epoxy for strength!

    Epoxy is marine duct tape.

    I would caution that statement. I have seen plenty of steam from my boat and others in the PNW when water and air are over 65 when surfing.

    Yes is not as hot as normal exhaust because of water being added but I wouldn't stick my hand behind my exhaust under load.

    That's two different things. That is condensation, like seeing your breath in cold air - that won't burn you. Have you never touched your exhaust manifold? It's toasty warm but not burn-you-hot. If it or the FAE pipes are hotter than that, you have a problem such as failing impeller or pump or some obstruction in the water flow.

    No I have not touched my exhaust manifolds, maybe I'll try your theory.

    I am wondering why would FAE make the system out of Metal if they could have used a Plastic which would have been MUCH cheaper in overhead?

    PVC begins to warp at 104c or 219F. Exhaust temps over 140 are more then hot enough to Burn you.

    Those of you thinking you will try ABS might find it interesting that at 98c or 208F ABS begins to distort as well.

    In FL my manifolds get hot enough to burn you. I can guarantee you that.

    I added a bar across the platform supports that then helps hold this in place. I also added screws into the exhaust pipes coming out of the boat with washers to help give the straps something to grab onto.

    Looks pretty good and exactly what I had pictured in my head. Glad to see such a great response to this.

    As I thought about this, it occurred to me that the manifold temperature would be directly related to the lake temperature; i.e. if your lake is 10 degrees warmer than mine, then your manifold is likely 10 degrees warmer than mine. Our lake never got above 70 this year, yours could have easily been 20 degrees warmer.

    I would also think that on a boat equipped with a heater, that the manifolds would end up cooler too. Because the heater is essentially a "heat exchanger" or a radiator. so if the heater core from the heater is bleeding off heat from the engine, then by the time it gets to the manifolds it would be cooler than a boat not equipped with a heater... Seems logical anyway.

    No, probably not. The heater taps off of the thermostat controlled water jacket. If the heater is on and taking some heat away from the motor, then the thermostat will just close off a bit of the incoming cold water. Basically that water temp is always 160 - or whatever your thermostat is. The exhaust side simply mixes the exhaust gas with a lot of cold raw water.
