2500 bucks is nuts for a set back.
MPD charges about 1,000 i think.
i dont see why any jet boat out there wouldn't benefit from a set back intake.
things to consider about setting yours back. with most intakes, you can machine the back of them to allow for a larger set back without breaking through the wood in the transom all the way. but, that still puts the hand hole cover right under the transom in a lot of boats depending on the angle of the transom. This means you'll need to fab a transom adapter that curves around the hand hole cover if you still want to be able to remove it.
