Hi
I am busy testing an EZ X20 outboard and would like to know the following :

1. Is it possible to get a different pitch propeller ? Currently delivered with a 10 inch and looking for a 12 inch ?

2. Can the EZ outboard app be updated so that the used w/h is included in the spreadsheet download ?
 
Thanks

In case I wasn't clear, the Magic Pie IV is only the hub no spokes/wheel. 

I would simply install the new stator assembly into the old magnet ring as it's a lot easier and quicker than swapping the rim and spokes and then having to true the rim and then re-tension the spokes after the first few rides.

The only damage that can sometimes occur when swapping the stators is if the laminations catch on the magnets while removing the stator.



If this happens, you can simply clamp them back into their correct position and apply some superglue to ensure they stay in the correct place.

The cover's flange is typically stuck to the mating flange on the magnet ring with sealant making it difficult to separate the two parts.

I usually thread a nut on the opposite end of the axle (freewheel or non-controller side) until the outer side of the nut is flush with the end of the axle. I then tap the end of the axle/nut with a large wooden mallet (or use a large hammer with a block of wood placed against the axle/nut to cushion the blow and prevent damage) until the cover on the controller side comes away.

Once the cover is unstuck you will need to remove the nut to allow the cover, controller, axle and stator assembly to be removed as a single unit, as I presume those are the parts you will be replacing in order to convert it from MPIII to MP4.
Check out this post for a description of how I did it.

However, if you just want to remove the cover alone, check out this post for further information.

Hi andto the forum.

If you raise the wheel off the ground and the maximum unloaded wheel rpm is still much slower than it should be, then it is most likely caused by a low throttle signal voltage.

The controller requires a throttle signal voltage of at least 3.25V to produce maximum motor rpm, but this voltage can be much lower if the controller's +5V regulated supply has been overloaded or has simply become weak over time.

If you are able to measure the voltage on the throttle signal circuit (with everything connected) this would help to confirm the suspected cause of the problem.

You should be able to measure the +5V output with a voltmeter connected between battery negative and pin 1 on one of the brake connectors:



If you wrap some insulation tape (or a small section of wire insulation) around the tip of the red meter probe, it should prevent you from accidentally shorting the pins inside the brake switch connector:



Check out this post for further information.

If the +5V supply is below 3.5~4V then the throttle will probably be unable to output the required signal voltage to produce the expected maximum rpm.Pi-80I
