I have just managed to dig the motors out from the depth of the garage: one is 12v, 22A, the other 12v, 25A. I assume that these will be too feeble to be of any real use?

Are these likely to be powerful enough to drive the boat if linked to an small outboard leg? The other alternatives I have considered are the scooter motors that are readiliy available on e-bay
