[Electric Boats] Torque

 

With the recent hp equivalency discussion I was wondering if you
could use torque as a valid measure. For example in my case could you just
look at the torque curve for a Yanmar 2GM20, find out how much torque there
is at about 2800 RPM or so (cruising speed), then take that value and find
an electric motor with the same torque at whatever you're going to use for
cruising RPM? I guess you might be able to bias it a little bit toward a
smaller electric motor since I do plan on using a bigger, slower turning
propeller than on the diesel installation. Any thoughts?

Thanks,

Jerry Barth
