SPT15 Marine conversion
Trying to find anyone who has an SPT15 jetcat. Im trying to custom make my own water cooled gearbox to convert this engine for marine use. Jetcat will not give me any photos or information on what the stage 2 turbine shaft looks like or how it enters the standard SPT gearbox. I can make my own water cooled gearbox that can withstand the power of the SPT15 but without knowing what the end of the stage 2 turbine shaft looks like it'll be pretty difficult. The marine gearbox that is made by jetcat (SPM5 model) will not support the power of the SPT15 (I asked if it was directly swappable). So my only option they said was to build my own gearbox that puts the output shaft speed to the appropriate levels for marine use. Why the SPT15? Well its over double the shaft horsepower compared to the SPM5 engine. The 94in catamaran boat they will go into wouldn't have the sufficient speeds im looking for with the power of the SPM5.
