Question about mounting Neu

[Nautilus]

So I go to mount my Neu 1515 motor to my new Emaxx and it turns out the mounting holes on the motor are not spaced far enough apart to get the 2 screws in at the same time. The motor holes on the stock motor plate are too far apart for the Neu.

I imagine people are not using just 1 screw to mount the motor, so what's up? Did I buy the wrong motor? (I did buy it from a boat place).
