OK it goes like this. The steps create several layers of disturbed water. If the hull is light, comes in under weight, you can run a higher X because of less disturbance.Many boats from factories are run with no interior and very little gas. Once the owner has a normal set up of fuel, people and all his personal junk, the boat weighs more, there is now a larger deep High and low PSI disturbance that is covered in more layers requiring the prop to grab more dirty layers of water creating more slip. The amount to lower is up to testing but I have too many boats that I just throw a spacer in and WHALA! the speed increases and the handling improves.Go figure. OLD NEWS rise the drive to go faster, good for conventional bottoms but lower your drive on Step hulls to get clean water that is useable. Putting money into props after heights are factored is key.
Tres, what kind of X Dimension data do you have on the 36' Apaches?
