Taking the numbers from the link provided -
Quote
Operating Voltage: 6-12 Volts


No Load Speed @ 12Volts: 6000RPM


No Load Current @ 12 Volts: 0.17Amps


@ Max Efficiency @12 Volts: 4930RPM


@ Max Efficiency @12 Volts: 1.6Amps
I would say any that are rated for your chosen voltage.  They start at 10A, which gives plenty of safety margin, but for a very few quid more, the 15 will do exactly the same job.

I have been running a Springer on 540, 6V lead acid
15A mtroniks and a 10A fuse for the last 8 years.
In the lake twice a week and at least one rescue each outing. Never even stuttered.
Should say though motor is water-cooled.
