Have not seen you
No I have not been spending much time in the yachting end of the business my main focus has been at other market primarily the military market were our exhaust design can be better utilize we feel after our last few large yacht sea trials with the MTU 4000 series we feel the best marked would be in this direction due to our ability to reduce exhaust heat signature and still maintain engine performance. And reduce weight and provide more space we will continue to support all of our previous clients with exhaust design needs.
I will soon be publishing a sea trail on a 140' vessel an R&D project were we did some additional cooling to reduce exhaust exit temperatures we achieved a 70 degree drop in exhaust exit temperature with and rise in main engine back pressure.
Based on this test and on the sea trails of the Trinity TO-61 and all five P J yachts from the 150' 170' & 215' all using the MTU 16V & 20V 4000 series I feel very confident we can back up our claims of reducing vessel heat signature to undetectable levels .
By not only not having to remove engine cooling water but now we know we can increase cooling water and still remain with engine companies requirements for back pressure.
I also feel there is an environmental benefit cooler exiting exhaust temperatures both air as well as exiting water temperatures the average wet exhaust system using conventional mufflers has an exhaust exit temp of around 200 plus degrees on our testing we show an exit temperature of under 90 degrees running in water of 80 degrees temp.
