Graupner 600-Series Motors

[GregS]

What is the difference between the Graupner 600BB SP 7.2 and the Graupner 600 Race 8.4? The specs look almost the same with the SP 7.2 having a no load rpm of 21,200 and the Race 8.4 21,000.

The 600BB SP 8.4 has a no load rpm of 17,000.

I'm looking for a replacement motor for my Aquacraft EP1 outboard which is powering my Profisherman Bass Boat. I will be running a 7 cell NiMH pack. I'm looking for maximum speed potential.

I assume the 600BB SP 8.4 will not be as fast as the other two for my application so it is between the 7.2 SP and 8.4 Race. What would people recommend?

I am not considering brushless as this will require significant modification work on the boat that I do not want to spend the time/money on.

Thanks,

Greg

Also, does anyone know the diameter of the motor shaft for these motors. I need to be sure it fits the coupler.
