There is no set patterns for install, however the intake does have perameters that need to be met. The setting needs to be square in the hull, centered on the center line of the keel, and level side to side. The intake depth is also critical, measure the intake depth with a straight edge down the keel through the pump area, it should not be above or below the keel plane. On the four corners of the intake the bolt holes are threaded, these are for adjusting the intake, when installing, and holding the intake in place while the epxoy cures. Other will chime in for more details, but this info will help determine if you are correct, about the intake not set right. Stay tuned for more info..
