No issues with SSM3's and 750hp. I think were rated to 800hp.

There are still new internal parts available for the #3 drive. I have new 1.31:1 straight cut, net forged upper gear sets ( the same "gear" as used in the #3A and the #5 drives, but manufactured with the "shank" as I call it, to be used in a #3 drive ) and new 1.75" dia.propshafts available for these drives. These pieces were manufactured in the USA. I can also supply the same upper gear that has a "polygon" internal for the #4 drive.
