The steam water pulsejet (SNPJ) - a modern derivative of the McHugh 'putt-putt' toy boat - was discussed at the 9th and 10 th IECEC. Further studies since then have revealed that, like its air breathing relatives, the SWPJ is a type of wave engine. Our paper first reviews the background literature (which has not been adequately done before) and then summarizes recent improvements in our understanding of the engine's operation. At low temperatures, the ideal cycle efficiency is almost identical with the Carnot limit, diverging above Delta T = 150 F. Maximum ideal cycle efficiency occurs in the 500-600 F range, and is 30 %-40 %.
