I have reversed one of the two seals in my new motors for Elementary. One seal keeps the oil in and one seal keeps the water out. I am confident this in addition to the compensation system will make for a clean leak proof set up. The ice is off the lake by my house, so my test lake should be open in a week or so.

<div>I just ran one of my motors filled with the WD40. It seemed to be very happy. I mainly just did it to clean the carbon build up out of the motor. I was surprised how sealed the motor was, it is open at one end where it mates to the gear box. I was able to fill it up without it leaking out anywhere. That could be an issue later when I want the mineral oil to fill all the voids. I might need to actually drill some holes to get some circulation . </div>
