Try it and see, but I don't see it making much difference on a V-20. Maybe a 2 MPH increase on the top end. A hydraulic jack plate would be nice though. Problem with jacking the engines on an offshore boat is you need the lower unit down in the water so the prop can get a solid bite and hold the bow of the boat, but maximum performance requires the engine to be mounted high up to get the prop right at the surface. You can find a happy medium, but to me it would be wasted money for an offshore boat unless you have a 20" transom and a 25" engine. Also make sure your steering cable doesn't bind up with the engine that far back, hydraulic steering would be a MUCH added expense that you don't really need with a 140.

Me personally I would go with a 10" set-back though if your going to run one. At least the 10" set-back would put the engine in cleaner water, and the 140's weight 10"s back shouldn't cause it to dunk to much.
