I did however got the following reply from GM, which feels like a real bummer. ![Sad :(](https://goldenmotor.com/SMF/Smileys/default/sad.gif)
Please swap to our new controller with new throttle .
You old set doesnt fit boat at all .
That's definitely not what you wanted to hear.

Perhaps you could rig up some form of mechanical brake on the propshaft that could be temporarily engaged in the Neutral position during manoeuvres.
Whilst I appreciate this is not an ideal solution, it should be a lot cheaper than replacing the controller and throttle, and perhaps it could be activated by an electrical solenoid controlled by a microswitch on the throttle mechanism to automatically engage the brake in the Neutral position.
You could then add a simple change over switch
(Regen switch) to automatically disable the propshaft brake and enable the Regenerative braking simultaneously, as you wouldn't want both activated at the same time.
Unfortunately, I am not aware of any programmable setting for the VEC controllers that would have any real effect upon this particular problem.
VEC controller? not tobe confused with the Vesc-project (opensource controllers)?
I was referring to the programmable settings in the PI800 software relating to the Golden Motor Vector controllers
(VEC200, VEC300 and VEC500 etc.) :

I have similar issues with MP2 (ebike hubmotor), I can run it in reverse. But if I touch that button while running forwards, I haveto come to complete stop, before going in ether direction. (had to change the parameter for regen-break to 80%, because my 36v battery became overloaded, -so thats not the solution)
The original version of the PD-280 programming software for the non-vector Magic Pie controllers had an option to select "
Immed" or "
Unimm" for the reverse mode:

However, I am unable to try this function out as I don't have the Reverse wires connected on any of my Magic/Smart Pies and this software does not work with the MP4 and MP5 vector controllers.
I presume that the "
Unimm" option will only allow Reverse to be activated after the wheel has stopped turning in the forwards direction, whereas the "
Immed" option would presumably select Reverse Immediately without waiting for the wheel to stop.
I did however post
a very poor quality video on YouTube over eleven years ago demonstrating the basic operation of the reverse function on my MPIII motor, but at that time I didn't have a programming cable suitable for the MPIII to try out the different Reverse modes. Unfortunately, the USB programming cable I had for the Original Magic Pie and later MPII did not fit the connector on the MPIII's newer style harness.
The Miromax version of the PD-280 software also allowed the motor direction to be changed, the Reverse Sound to be turned On or Off, and the Regenerative braking could be set right up to 116% instead of 100%:

The reverse sound only worked on later MPI & MPII internal controllers equipped with a beeper and some BAC-281P external controllers.
