  • There are propane hose connections and a solenoid inside the hull — they must be inside the sealed propane locker or on deck where fumes can't get below and cause an explosion.
  • The solenoid and hose is poorly "secured" with braided line attached to wood blocks, attached to the hull with putty. If the solenoid or hose gets loose, they could become damaged and leak.
  • The diesel heater exhaust (white braided tube) has a single layer of insulation, which may allows excessive exhaust heat. If the exhaust overheats, it could cause a fire and exhaust can leak into the boat.
  • The propane hose is contacting the diesel heater exhaust. If the hose burns through, propane will leak into the boat and may explode. American Boat and Yacht Council (ABYC) standards require a nine-inch clearance between a dry exhaust and all hoses and wiring.
  • Wiring is contacting the propane hose ­ it's not hard to imagine what happens if the wire shorts and heats up red-hot.
  • Wiring is attached to the diesel heater exhaust with nylon zip ties, which could damage both, causing a propane leak and/or a red-hot shorted wire.
  • The wiring in general is hard to follow and poorly supported. Unsupported wires can break or chafe and short out, causing a fire. ABYC standards require wires be supported every 18 inches.
