I am going to do the gearbox oil change as my powerbox is arriving soon. When I remove the metal cover I am going to see if there is room to fit a naca duct in to the metal cover. I have found a duct with a scoop and it has a hose connection so I can route the air to the motor. My concern is only if rain will splash up on to the electrics…I am sure it would not hurt the motor as it would be hot enough to just steam off but I do not want to cause any damage. Any thoughts?
I may need to check there is enough air gap for the hot air to escape. I wonder if we could pipe hot air off the motor in to the cabin to create a mini heater?
