I would be interested in whether or not this motor would pull an a/b impellar to 6500 rpm's when the pump is fully loaded.
Looking at how fast the torque falls off in relation to the horsepower gains I would doubt that could happen.
Not saying this is not a good motor. Just that the pump absorbs so much horsepower at the higher rpm's.
I hope it reaches your expections. Please let us know.
Thanks,
Kojac.
I'm going to guess that when he runs his boat with this new set up he will about 5800 or so
