I decided to buy the liquid cooled version of the 10 KW 48v motor for use on an outboard. Many outboards just use the lake water to cool the engine on typical internal combustion outboards. I figure I can do the same for this motor since I'll never take in salt water.

If anyone has done this, I have two questions about the approach:

1. Is the motor self priming or do I need to pump water through the motor with a separate water pump?
2. Did you install a filter at the inlet hose? If so, what filter and do you have any trouble mounting it or getting it to pull water into the motor?

Thanks for any advice!

........Does anybody have a used seat post battery rack they would like to sell?  (Listed here for $60.81 SKU RAK-002) The one that mounts to the seat post ONLY....OR know where one can be ordered new?

Hi Mark,

Here are a few suggestions that may help:

Double check that all the connectors are properly plugged together, just in case a wire has been accidentally snagged/pulled whilst putting the bike away etc. or perhaps they were not fully plugged in initially.

Make sure that all the wiring is safely secured away from moving parts i.e. the wheels/tyres, chainwheel, steering and suspension etc. to prevent them from being chaffed or crushed.

Make sure the controller's battery voltage setting is correct for your battery. If it is set to 36V and you are using a 48V battery, it may have worked last time if the battery was partially discharged and its voltage was below 50V.
The voltage of a fully charged 48V battery would be well above the 50V maximum that the 36V controller settings will safely allow, and the motor would therefore not be able to work.

Make sure both brake levers are fully released, as activating the regenerative braking function also disables the throttle.

Was is wet, raining or did you hose down the bike after your last ride? If so, it may be possible that some water has found its way into one of the connectors, or perhaps inside the thumb throttle unit itself.
If water was causing the throttle signal to be higher than expected, when the controller is switched on, the motor would be unable to run due to a safety feature of the controller that prevents the motor from running if the throttle is activated when the power is turned on.

Check out this thread for further information on how water can affect the throttle operation.

Hopefully you will find something obvious.

Here are some steps you can take to troubleshoot and potentially fix the issue:

Check for Loose Connections: Ensure all connections related to the Mosfet are secure and properly seated. Loose connections can cause irregularities in the system's operation.

Inspect for Damage: Examine the Mosfet component for any physical damage such as burns, cracks, or signs of overheating. If there is visible damage, the Mosfet may need to be replaced.

Reset the Control Box: Try resetting the control box by powering it off, waiting for a few minutes, and then powering it back on.
Sometimes, this simple step can resolve minor issues. Restarting the machine is like relieving stress with adult sex films. It is a simple but very effective way.

Consult the Manual: Refer to the user manual or documentation provided with your Vector 200 control box for specific troubleshooting steps and error code interpretations. It may offer additional guidance on resolving the Mosfet protection error.

Contact Customer Support: If the issue persists or if you're unsure about performing any troubleshooting steps, it's best to contact the manufacturer's customer support or technical service team. They can provide expert assistance and further guidance on resolving the problem.

Keep in mind that working with electrical components can be dangerous, especially if you're not familiar with the equipment. If you're unsure about how to proceed or if the issue involves complex repairs, it's advisable to seek assistance from a qualified technician or professional.

Hi Don,

As you have steel forks that are also fitted with a torque arm you don't need to worry, as the load on the headset is significantly greater from heavy braking forces applied to a conventional wheel than the torsional forces generated from a front mounted hubmotor under full power. 

Forks that are able to be used with disc brakes would be the best option for a front mounted hubmotor as they are designed to withstand torsional forces at the lower end, whereas non-disc brake forks only had to withstand directional forces from the wheel's axle:



The biggest safety concern with a front mounted hubmotor is that the fork's dropouts are simply not designed to cope with any torsional loads from the axle in either direction when a conventional front wheel is used as the wheel bearings prevent this from happening.
However, with a hubmotor, the high torsional forces produced by the stator have to be transmitted through the axle, which is why torque arms should always be fitted when using a hubmotor to help withstand the bidirectional torsional forces produced by the axle within the dropouts while under power and during regenerative braking.
