not sur eof the BTU, i can check when I am down there next time.
Our unit is located directly across from the head, in the small locker. th eonly vent comes out on the wooden wall, err, bulkhead, whatever, on the port side.
at this time, it only runs on shore power, but keeps things frosty when at dock on hot summer days.
i am thinking of rigging up some type of ginny so that we can also use it at anchor.
