The boat-trolling motor need to have the propeller changed to be able to
The ideal one is those that are DC Brushless types,( they are more
expensive ), look for one that requires 24 or greater battery voltage for
The propeller needs to be calculated for the "river" velocity and the needed
RPM ( TSR), check AMPAIR submerged generator website to observe the
propeller size and the energy that is reported at different velocities.
