In 2018, the Marine Corps Systems Command required a 55HP non-gasoline burning outboard engine (NBOE) to run on JP5, JP8 and diesel fuel to comply with the DoD “single battlefield fuel” directive. (link to file NBOE_PIS_2018.pdf)
XRDi developed a prototype which was designed and tested to be submerged in 60ft of water, left for 60 days, surfaced and immediately started on JP5, JP8, and diesel.
Rodler commissioned a high efficiency water jet outboard prototype, which XRDi developed using a 690cc Cayuna engine. This unit used XRDi’s patented fuel delivery system giving it multi fuel capability.
