The static thrust measurements aren't necessarily tested in any standard fashion, so I'd caution any direct comparison between brands. Also static thrust by definition doesn't mean much one the boat starts to move. Then we are concerned with rpms and propeller dimensions (diameter, pitch) which will directly relate to propulsive force of the vessel while underway.
Another difference to consider is duty cycle. In my opinion trolling motors are built for intermittent duty, and work well in those applications. A true electric outboard is designed to provide close to full power for continuous duty, or in our case as long as our batteries can last!
