We called them speed props or power props... anything with a prop can have blade pitch, blade depth (chord), and length changed to bias toward power or speed. We used to play with props on our RC planes. A power prop could let us climb vertically at low speed with a “40” sized plane and a “40” engine, but the engine would never get near full RPM. A speed prop would require a much longer runway to take off, and the vertical, low speed climb would be nil, but the plane would hit a higher speed, and the engine would hit max RPM. Get too biased in either direction, and you suffer too much degradation.
The same will go for your outboard. Depending on the prop, your motor will not hit max RPM while pushing your boat, but it will have the power you need.
