10 Amps is 5 amps more than the motor will generate on a regular basis. Since there is no 'correct' fuse for that modification, I would go with 10. You can see normal amperage readings here:

in the Heater section, but the most I have seen with a PM354 12v replacement motor is a little less than 4 amps.
