After construction, the Sub Marine Explorer was partially disassembled and transported to Panama in December 1866, where she was reassembled to harvest oysters and pearls in the Pearl Islands. Experimental dives with the Sub Marine Explorer in the Bay of Panama ended in September 1867 when Kroehl died of "fever". The craft languished on the beach until 1869, when a new engineer and crew took it to the Pearl Islands to harvest oyster shells and pearls.
