The engines installed in the NEW Mount at Lakeport in 1940 were a pair of refurbished
Herreshoff 750 HP Triple Expansion (Steam) engines built in 1920. These were NOT Walking Beam engines. They were designed for screw propellers. Their performance was less than hoped for in this hull for various reasons. It took some time to dial in all the parameters.
WWII had just started for the US..and everything came to a screeching halt. The Coast Guard comandeered the engines for the war effort and the Mount settled in for a sleep, until the war was over. In the meantime..the owner..Capt. Leander Lavallee couldn't make the payments because buisness was OFF during the war. He went bankrupt. Lest one get confused: There were also other Lavallee's involved in steamboating on the lake..including The Mount Washington at various times.
In 1946, the
Modern Engines were installed. A pair of Enterprise Diesels..which remained in service until last year when new Catapiller Diesels were installed.
