    It depends a lot on the boat it is on. If it has to lug along at WOT to stay up to speed on plane, it won’t help much because it will start to sink down off plane when you back off on the throttle. On the other hand, on a nice boat that planes easily and maintains it’s speed when you back off to the fuel saver position, it does make a difference.
