[Electric Boats] Efficiency of mars motor

 

I'm trying to use the spreadsheet to estimate the best gear ratio. Its got a lot of info but a steep learning curve. Finally figured out how to match the required HP to the HP for a given diameter/pitch. So now I think that my best propeller RPM should be 1020. So is there a best RPM to operate the 72 volt mars motor at? Best in this case would be RPM rather than maximum power.
