    NEU Motors were and are silicone wires equipped but now they are black.
    Gary, if you had vibrations in the boat you could listen that something was wrong.

      Neu was having problems with wire strands breaking inside the can on each lead and they were seeing premature motor failures. In an effort to repair the issue Neu Motors decided to use more flexible wires. Prior built motors had the 3 leads as extensions right off the windings. No splices or joints like most other manfacturers. Now they terminate the winding leads inside the can and add the silicone wire extensions.

      But in doing so, they added a butt splice. Always an issue on any motor as it can have connectivity problems and since its usually a dissimilar metal, it changes (relative) either electrically or physicaly as heat (amps) increases.

        I wonder if that is my problem or i am just overloading {ovecourse} the motor.

          I cant see Neu just not reasearching the wire mod. Since I have not spoke to a Neu Engineer to confirm, I would err on the side of them doing their home work and having done it right. Like with a spot welder during the crimp process. Or maybe they dont even use a crimp/butt splice. I hope I didnt alude to Neu motors having a poor manufacturing process. I was just stating what I have seen on other motors I have inspected internally when changing out bearings.

            Well its off through snail mail back to NEU. I will just wait and see what they have to say this time. I will ask about the wires when they call aswell. Hope they can warranty it.

              They will for a small cost of arround $50.00 if i remember right.
              I had the same problem with 1521 1.5D and also lost couple of high amp esc'c....
              They told me the same: vibration....
              IMO wires coming out via the back plate holes should be isolated in high temp silicone holders....

                The wires on my 1515 2.5D have silicone grommets around them. Worst case if it doesnt have them take the motor apart and drill the holes bigger so you can add some

                  Well the motor is at NEU's and should be back in Jan. I had an in depth conversation with Steve on my issue and he is going to cover it cost wise. An attempt will be made to secure the wires coming out of the bell and he will change around the winding and rotor assenbly for a little more rpm/speed...I hope. I will update the post when motor returns and hopefully there will be no ice on the lakes.
