The defense of the VRO system is notable, but it is still a not-so-great design. The pump is great, but it's the delivery system that is the weak spot.
A kink in a hose, a crack in a fitting, or many other small things can cause the oil to not make it from the remote tank to the VRO, and that ends the engine permanently. Yamaha's idea of the main oil tank feeding into a small onboard tank that gravity feeds oil to the engine would solve this problem, but OMC never went that way. Feeding directly from the remote oil tank means that ANY kind of delivery problem, VRO being the cause or not, equals a destroyed engine.
There is a reason OMC commercial engines did not have mixers. Commercial consumers need long term reliability. It's probably true that the VRO system is unfairly vilified, but disabling that system removes one more thing that can destroy the motor.
