Stus-List Re: Question re heater transom exhaust thru hull

If it is mounted on the hull under the reverse transom then one wouldn't be able to run the unit while sailing / motoring or even anchored in any chop, due to the risk of submerging the outlet and choking the unit.  Espar instructions specifically recommend mounting on the transom.

That is where Persistence Engine exhaust comes out as well.  I believe the concern for a diesel heater exhaust is water ingress from a following sea so it is generally advised to have it a specific distance above water level.  That could work though with a high exhaust loop in the boat but would be a bitch to access from the outside for installation with the boat in the water!

Mike, I don't know if it changes anything but ALL of my discharge and exhaust ports come out under the reverse transom.  You can see it in the video linked below.

    Wondering if anyone on this list has installed a forced air heater
    with the exhaust thru hull on a reverse transom?

    The thru hull I purchased can be seen has an elbow to force the
    exhaust hose into an upward loop but with a reverse transom there
    is potential for water to build up at this elbow joint.

    Has anyone experience with this and how it is typically resolved?

    Thanks
