Hey all ,
I have a ongoing argument with a buddy that says if I turn say a 1/4" off the flywheel on a mercruiser I/O (or any other I/O) that it will make the motor spin up faster resulting in a better holeshot and more speed.
I say that it will result in less torque and mess with the balance of the engine(unless internally balanced).
Anyone got an apinion?

in my mind it seems like you would both be correct.... It SHOULD rev faster, but you would have less torque.... Absolutely nothing to back it up though.... I would say that Chevy/Mercruiser have designed it to the current thickness for a reason!
