The boat is powered by a Semple 3 X 4 double acting single cylinder condensing engine producing about 5 h.p. Best estimated speed, with 120 pounds on the gage is 6.5 kits. Down comers are attached to the steam dome and the mud drums. The mud drums are connected in the rear of the boiler. Pressure relief valve is set at 150 psi.
Heat is provided by a converted domestic type oil burner.
The 115 volt 1725 rpm motor was replaced by a 12 volt d.c. motor, while the 115 volt, primary, with secondary of 10,000 volts each leg transformer was replaced by a 12 volt d.c. spark coil. This combination provides power to turn a Sundstrand mini pump at 100 psig, combustion air and spark to ignite the fuel spray. The boiler was manufactured by Beckmann and the oil burner was also converted by them. From a cold start, I can have 80 psi pressure in 15 minutes. Lloyd Beckmann runs the small boat shop and actually builds the boats.
