if it is direct drive , you could fit a higher rpms motor--depending on the number of poles in the motor will change the rpms
if not direct drive , change the pulley/cogs ratios
On the rascal, if your driving along and it suddenly stops, the throttle lever could be bad or the speed control could be bad or both. A battery lead maybe loose. The tiller cable may have slid back causing line interruption.
The flashing 4 indicates current timeout, the scooter may have been going up a steep hill, over heating the motor, turn off and allow motor to cool. then try again. if this happens on flat ground then check the parking brake, it maybe hanging up causing the motor to over work.

your problem is related to the overload breaker on the chair you need to figure out why the breaker is tripping either due to batteries going bad or the brushes in the motor need adjusting or replaced , also you need to check the automatic brake is releasing completly a dragging brake will cause the auto reset breaker to trip
It is the same as a Rascal 600 only the 300 has smaller wheels.
The manual is not much help on the brake, it does not go into repairing the bake, except for checking voltages and replacing the microswitch, some tips are a little oil on the detent balls help to keep it free and movable, but don't get oil on the brake pad. Scooter Doctor App
Check the electric brake its most likely not disengaging from the motor case causing the motor to strain and overheat. You can unscrew the brake assembly from the rear of the motor and check to see if the brake pad is free and moveable If you can support the rear wheels off the ground and engage the throttle you should be able to hear and see the brake pad release. You can drive the scooter with the brake off the motor but do not disconnect the brake wiring. The scooter looks for that connection to work if it can't find the brake then it will flash and won't operate. now if you do hang the brake off the motor remember you do not have brakes and the scooter can roll backwards when going up ramps or on hills. You will have to replace the brake assembly and reattach it to the motor to have brakes
me tool time you checked or changed about everything but did you check the electric brake. Sounds like the brake is not working or is working intermittentaly. The controller needs to get the right reading from the brake or the scooter will not go and when you release the throttle the brake should engage immediately. I can't give you a well thats the answer but you should at least ohm out the brake. If you can call rascal Company on Monday and ask for tech support they can give you what the reading should be Hope this helps
On some scooters it is possible to change the polarity of the motor. If its a two brush motor (most are) you can just swap the red and black wires around in the connector plug for the motor. Make sure you get the right wires if you do this but I have to point out that there is obviously a problem with the scooter and I would strongly advise you to get it looked at by your local dealer as the problem is potentially serious and may cause other problems aswell. I cant really understand why it would only go backwards. May be a throttle pot problem or main controller fault. Either way, as I said, best get it looked at as even if you do swap the wires, it is most likely that the scooter will only travel forward at the usual speed for reverse, normally 2mph! Hope this helps...
Is there any change speed when you change from 4mph to 8mph ?
if not first check the controller under the seat, normally a black box, make sure that all connection onto the controller are clean and tight,
Check the motor brushes, undo the screw caps carefully,these can be brittle , remove the brushes clean , make sure the brushes move freely within the motor,
Check the brake on the side the motor, this normally has a freewheel attached to it,
Remove the brake unit but do not disconnect the two wires, and test again is the brake clicking when you power away, if not it's not releasing hence the slow speed, check the brake for open or shorted connection.
the batteries could be the problem, is it possible to try some other batteries, silly question , how steep is this hill ? remember scooters cannot climb steep hills as the motor will shut down due to the increased load.
1 Year old batteries ok ? but if they get used on a non daily basis and are not fully charged after use, I would question the batteries but again the motor could be overloading,
How much do you weight ? sorry for the personal question but it all loads the motor and that increases the current and that will cause the motor controller to shut it down.
