    Default Twin cat motor rotation?

    I just finished an Aeromarine 36" Avenger twin Q. What are the benefits of outward rotation verses inward rotation? I've heard that you will be more more stable in the corners with the outward rotation and faster on the straights with inward rotation. Any opinions or advice??

    I have the same boat and I race it oval and Offshore races with only a prop size change.
    My GPS comes back at 78MPH for peek speed.
    I run mine outbound for better control when cornering.

    Nice! I've got mine set up with outward rotation as well. Where do you have your CG set?

    Once you get comfortable with the boat, its a fun experiment to swap the rotation (motors and flex cables) and compare the results to actually see and feel the difference.

    I've got a cheetah twin P that I run inward rotation and it runs great. Thought I would switch it up on this boat. I will swap rotation at some point and see what I like better. Gotta keep trying new things for the sake of progress.
