Anyone out there with forced air heat on a Crealock 34?
My older Espar 3DL has been acting up and since it is now obsolete and parts becoming unavailable, I have considered replacing it rather than rebuilding. As would be on a boat, nothing is that simple. The equivalent model is a D4, but it's not a direct replacement. The dealer, Boat Electric in Seattle, tells me that the D4 requires a 4" air duct off the heater at least until the first Y. Unfortunately, I have 3" duct and it goes the engine compartment and aft of the rudder post, the absolutely most inaccessible part of the boat. I can't imagine getting down there to replace it, let alone re-cutting the holes through the bulkheads to 4".
Has anyone dealt with anything similar? If you have an Espar heater, which one? How is your air duct routed?
