Astro Cobalt-25

Which motor is more powerful?

Astro Flight p/n 325 marine cobalt-25 racing motor or the 1800 kV 6-pole brushless motor used in the Pro Boat Stiletto?

Yes, the Astro is decades out of the running. Almost ten years ago I substituted an Astro 25 for a top-end 700 brushed motor and the boat lost 5 mph with the Astro - even with lots of prop changes. The Astros are pretty paperweights today.
