Diesel/Kerosene Heater Installation on Fishing Boat 

The exhaust pipe is not double wall (I believe) the double wall that I was referring to is the silicon boot which has a layer of insulation sandwiched between the two silicon layers. The exhaust pipe is the actual webasto pipe that they sold by the foot. Its a thicker gauge compared to the exhaust pipe material shipped with the Chinese heater. The RV/Marine heater distributor was Rixens Enterprises in Sandy Oregon.

Its not too bad. In this install (in this specific video) its a hard top; so for the most part you don't hear it other than when you are at the dock and right in front of the exhaust port. At the helm, I do not hear it. They do make exhaust muffler/silencers, but you need to be careful with some of these as they have a small drain on many of them and they could potentially leak exhaust through these into the cabin. Personally, the exhaust noise has not been an issue with where I placed the exhaust port outside the hull and pointed away from passengers (on this boat and on another cabin cruiser). I think the fuel pump clicking noise and getting that pump noise muffled is more advantageous as that rhythmic clicking drives me nuts.🙂

@@AFaO Great to hear. I am installing mine today. I was torn about going out the starbord side or taking it out clear to the back of the boat. Thank you for your information!!

@@jhspraker Ideally whatever is a shorter path and ideally if you can make sure the exhaust is going downhill/slight downward slope. That way any condensation can naturally run out. Some folks have had to use a condensation trap if the exhaust pipe is going uphill and is long. Short lengths going uphill (less than 3'), I have not had any issues with as long as you run the heater hot. But long runs going uphill can be troublesome with condensation.

@@salmonkiller2545 mostly kerosene because its cleaner. But if its not available where I am at…I will use diesel.
